  • From the editors
    - Nat Rev Immunol 10(6):377 (2010)
    When Élie Metchnikoff shared the Nobel Prize in 1908 with Paul Ehrlich, it marked the recognition of synergism in the immune system between cellular (phagocytic) and humoral (antibody) components. However, not until 1989, when Charles Janeway Jr postulated the hypothesis of pattern recognition receptors for pathogens, did phagocytes and innate immunity once again come to the fore.
  • HIV: Calculating control
    - Nat Rev Immunol 10(6):379 (2010)
    A new study based on computer modelling brings us a step closer to understanding why certain individuals can control HIV infection for long periods of time without therapy. The authors predict that expression of the HLA-B57 allele by these individuals generates a naive CD8+ T cell repertoire that has a larger fraction of cells that recognize the virus and that these cells are more cross-reactive to mutants of targeted viral epitopes, features that may contribute to improved control of HIV.
  • Innate immunity: Experience helps
    - Nat Rev Immunol 10(6):380 (2010)
    The mechanisms involved in the recognition of pathogens by innate immune cells and the subsequent induction of adaptive immunity are well known. But can cells of the adaptive immune system regulate innate inflammatory responses?
  • T cell responses: PU.1 in time saves nine
    - Nat Rev Immunol 10(6):380 (2010)
    The differentiation of T helper (TH) cell subsets is controlled by unique sets of transcription factors; these regulate the expression of cytokines and other genes that are important for the effector functions of each subset. Recent reports have described an interleukin-9 (IL-9)-producing population of T cells, which is induced in vitro following culture with IL-4 and transforming growth factor-β (TGFβ).
  • Therapeutic cancer vaccine approved
    - Nat Rev Immunol 10(6):380 (2010)
    The world's first therapeutic cancer vaccine has been approved by the US Food and Drug Administration (FDA), heralding a major breakthrough in the struggle to harness the immune system to fight tumours.The new vaccine, Provenge (sipuleucel-T), will be used to treat men with advanced prostate cancer and is tailored to the individual: each patient's immune cells are isolated and primed against tumour-specific antigens in vitro before being infused back into the patient (New York Times, 30 Apr 2010).
  • In brief: Innate immunity, Cytokines, Antibody responses
    - Nat Rev Immunol 10(6):381 (2010)
    NLRC5 negatively regulates the NF-κB and type I interferon signaling pathways Cui, J.et al. Cell 141, 483–496 (2010)NLRC5 (NLR family, CARD containing 5) is a member of the NOD-like receptor family of intracellular pathogen recognition receptors, but its physiological function is not known.
  • Cytokines: Cytokines reach out
    - Nat Rev Immunol 10(6):382 (2010)
    It is generally thought that interferon-γ (IFNγ) and interleukin-4 (IL-4) (the canonical T helper 1 (TH1)-type and TH2-type cytokines, respectively) function locally and only activate those cells that are in close proximity to the cytokine source. Perona-Wright et al.
  • Innate immunity: The stress connection
    - Nat Rev Immunol 10(6):382 (2010)
    Smoking and prolonged stress have been linked to increased susceptibility to bacterial infection. New research in Cell Host & Microbe now shows that this may be caused by a decrease in antimicrobial peptide (AMP) activity as a result of increased stimulation of a neuroendocrine signalling pathway.
  • V(D)J recombination: RAG recombination centres
    - Nat Rev Immunol 10(6):383 (2010)
    The recombination of variable (V), diversity (D) and joining (J) gene segments that form immunoglobulins and T cell receptors is essential for the generation of a highly diverse repertoire of antigen receptors. V(D)J recombination is initiated by binding of recombination-activating gene 1 (RAG1) and RAG2 to recombination signal sequences (RSSs) that flank these gene segments.
  • Natural killer T cells: Limiting B cell autoimmunity
    - Nat Rev Immunol 10(6):384 (2010)
    The production and deposition of autoantibodies by B cells is a cardinal feature of systemic lupus erythematosus (SLE). Defective apoptotic cell clearance, as well as decreased numbers of invariant natural killer T (iNKT) cells, has been described in patients with SLE; however, whether these two observations are linked — and if so, how — is not known.
  • T cells: TLRs deliver a direct hit to TH17 cells
    - Nat Rev Immunol 10(6):384 (2010)
    Toll-like receptors (TLRs) generally promote adaptive immune responses indirectly by activating innate immune cells. Now, new research shows an unexpected direct role for TLR2 signalling in T cells themselves, promoting the differentiation and proliferation of T helper 17 (TH17) cells.
  • Innate immunity: A chain reaction
    - Nat Rev Immunol 10(6):385 (2010)
    New research published in Cell adds to the evidence indicating a crucial role for protein ubiquitylation in regulating immune responses. But in this example, free polyubiquitin chains in the cytoplasm — rather than the direct ubiquitylation of immune factors — are important for activating innate antiviral immunity.
  • In brief: Innate immunity, Immune regulation, T cell development
    - Nat Rev Immunol 10(6):385 (2010)
    Innate lymphoid cells drive interleukin-23-dependent innate intestinal pathology Buonocore, S.et al. Nature 464, 1371–1375 (2010)The production of interleukin-17 (IL-17) and interferon-γ (IFNγ) during colitis is often attributed to CD4+ T cells.
  • The SYK tyrosine kinase: a crucial player in diverse biological functions
    Mócsai A Ruland J Tybulewicz VL - Nat Rev Immunol 10(6):387 (2010)
    Spleen tyrosine kinase (SYK) is known to have a crucial role in adaptive immune receptor signalling. However, recent reports indicate that SYK also mediates other, unexpectedly diverse biological functions, including cellular adhesion, innate immune recognition, osteoclast maturation, platelet activation and vascular development. SYK is activated by C-type lectins and integrins, and activates new targets, including the CARD9–BCL-10–MALT1 pathway and the NLRP3 inflammasome. Studies using Drosophila melanogaster suggest that there is an evolutionarily ancient origin of SYK-mediated signalling. Moreover, SYK has a crucial role in autoimmune diseases and haematological malignancies. This Review summarizes our current understanding of the diverse functions of SYK and how this is being translated for therapeutic purposes.
  • Cross-priming in health and disease
    Kurts C Robinson BW Knolle PA - Nat Rev Immunol 10(6):403 (2010)
    Cross-priming is an important mechanism to activate cytotoxic T lymphocytes (CTLs) for immune defence against viruses and tumours. Although it was discovered more than 25 years ago, we have only recently gained insight into the underlying cellular and molecular mechanisms, and we are just beginning to understand its physiological importance in health and disease. Here we summarize current concepts on the cross-talk between the immune cells involved in CTL cross-priming and on its role in antimicrobial and antitumour defence, as well as in immune-mediated diseases.
  • Securing the immune tightrope: mononuclear phagocytes in the intestinal lamina propria
    Varol C Zigmond E Jung S - Nat Rev Immunol 10(6):415 (2010)
    The intestinal landscape comprises the host's own tissue and immune cells, as well as a diverse intestinal microbiota. Intricate regulatory mechanisms have evolved to maintain peaceful coexistence at this site, the breakdown of which can result in devastating inflammatory bowel diseases (IBDs). Mononuclear phagocytes promote both innate and adaptive immune responses in the gut and, as such, are essential for the maintenance of intestinal homeostasis. Here, we review the origins and functions of the mononuclear phagocytes found in the intestinal lamina propria, highlighting the problems that have arisen from their classification. Understanding these cells in their physiological context will be important for developing new therapies for IBDs.
  • Phagocyte partnership during the onset and resolution of inflammation
    Soehnlein O Lindbom L - Nat Rev Immunol 10(6):427 (2010)
    Neutrophils, monocytes and macrophages are closely related phagocytic cells that cooperate during the onset, progression and resolution of inflammation. This Review highlights the mechanisms involved in the intimate partnership of phagocytes during each progressive phase of the inflammatory response. We describe how tissue-resident macrophages recognize tissue damage to promote the recruitment of neutrophils and the mechanisms by which infiltrating neutrophils can then promote monocyte recruitment. Furthermore, we discuss the phagocyte-derived signals that abrogate neutrophil recruitment and how the uptake of apoptotic neutrophils by macrophages leads to termination of the inflammatory response. Finally, we highlight the potential therapeutic relevance of these interactions.
  • Mast cell-orchestrated immunity to pathogens
    Abraham SN St John AL - Nat Rev Immunol 10(6):440 (2010)
    Although mast cells were discovered more than a century ago, their functions beyond their role in allergic responses remained elusive until recently. However, there is a growing appreciation that an important physiological function of these cells is the recognition of pathogens and modulation of appropriate immune responses. Because of their ability to instantly release several pro-inflammatory mediators from intracellular stores and their location at the host–environment interface, mast cells have been shown to be crucial for optimal immune responses during infection. Mast cells seem to exert these effects by altering the inflammatory environment after detection of a pathogen and by mobilizing various immune cells to the site of infection and to draining lymph nodes. Interestingly, the character and timing of these responses can vary depending on the type of pathogen stimulus, location of pathogen recognition and sensitization state of the responding mast cells. Rec! ent studies using mast cell activators as effective vaccine adjuvants show the potential of harnessing these cells to confer protective immunity against microbial pathogens.
  • Unravelling mononuclear phagocyte heterogeneity
    Geissmann F Gordon S Hume DA Mowat AM Randolph GJ - Nat Rev Immunol 10(6):453 (2010)
    When Ralph Steinman and Zanvil Cohn first described dendritic cells (DCs) in 1973 it took many years to convince the immunology community that these cells were truly distinct from macrophages. Almost four decades later, the DC is regarded as the key initiator of adaptive immune responses; however, distinguishing DCs from macrophages still leads to confusion and debate in the field. Here, Nature Reviews Immunology asks five experts to discuss the issue of heterogeneity in the mononuclear phagocyte system and to give their opinion on the importance of defining these cells for future research.
  • Corrigendum: Exploring the full spectrum of macrophage activation
    - Nat Rev Immunol 10(6):460 (2010)
    The authors would like to include as an addendum the contribution of R. Stout and J. Suttles to the conceptual framework of macrophage plasticity that was mentioned in our Review. Their ideas on the ability of macrophages to change their functional phenotype in response to their tissue environment were previously published in two review articles (J. Leuk. Biol. 76, 509–513 (2004) and Immunol. Rev. 206, 60–71 (2005)).

In an attempt to replicate this observation, we genotyped this variant in eight case-control and three trio-family collections (in total 22,854 individuals were considered, comprising 8,391 cases, 8,052 unrelated controls and 2,137 trio families). None of these studies showed evidence for a statistically significant association; more than half of the studies showed a trend in the opposite direction (Fig. 1). Based on the odds ratio (OR) reported by Aulchenko et al.1 (OR = 1.35), each of the collections we studied had >80% power to demonstrate association at the 5% significance level, except for the two smaller Australian studies; a population where association with this KIF1B variant has already essentially been excluded2. We also found no evidence for association with rs10492972[C] in analyses that considered all of our data toge! ther or those that pooled our new data with the allele counts reported by Aulchenko et al.1 (final P = 0.1). Given the P value originally reported by Aulchenko et al.1 (P = 2.5 × 10−10), it is important to consider why this association has not been replicated.

  • Reassessing evidence for a postnatal mitochondrial genetic bottleneck
    Samuels DC Wonnapinij P Cree LM Chinnery PF - Nat Genet 42(6):471-472 (2010)
    Mitochondrial DNA (mtDNA) mutations are a major cause of maternally inherited human disease. Mothers often harbor a mixture of mutated and wild-type mtDNA (heteroplasmy) and transmit varying proportions of mutated and wild-type mtDNA to different offspring.

Our recent study5 concluded that most of the intergenerational variance in heteroplasmy occurs as a result of the replication of a subpopulation of mitochondrial genomes in postnatal life. Samuels et al.1 object to our analysis on the grounds that we failed to normalize the values of heteroplasmy variance in germline cells for the initial heteroplasmy levels in the mothers, and they suggest that our conclusions were premature. They correctly state that the variance in heteroplasmy is expected to be maximal when the initial level of heteroplasmy is 0.5 and is expected to decrease as initial heteroplasmy levels approach the boundary conditions of 0 and 1. Normalization for initial heteroplasmy levels has the effect of flattening all variance measurements (compare Fig. 1a,b in Samuel et al.1)! but in fact has very little impact on our data except for those data collected in postnatal day (P) 8 animals, where we concede the differences we reported could have been due to the very low initial values of heteroplasmy of the mothers. They focus their discussion on two data points (P8 and P11) and state that there does not appear to be any discernable difference between the two.

We sequenced the exomes of four affected individuals (cases) and found heterozygous de novo variants in SETBP1 in all four. We also identified SETBP1 mutations in eight additional cases using Sanger sequencing. All mutations clustered to a highly conserved 11-bp exonic region, suggesting a dominant-negative or gain-of-function effect.

Here we show that a mutation of IQSEC2, encoding a guanine nucleotide exchange factor for the ADP-ribosylation factor family of small GTPases, caused this disorder. In addition to MRX1, IQSEC2 mutations were identified in three other families with X-linked intellectual disability. This discovery was made possible by systematic and unbiased X chromosome exome resequencing. View full text Figures at a glance * Figure 1: Identification of IQSEC2 mutations. cDNA (NM_001111125) and protein (NP_001104595) annotation of individual mutations is shown for each family. Pedigrees of MRX1 and MRX18 families have been updated since their last publication. Open symbols represent normal individuals, filled squares represent affected males, open circles with middle dots represent carrier females and cross-hatched squares represent males with learning problems but without an IQSEC2 mutation. Two carrier females with some learning problems from the MRX18 and AU128 families are shown with half the circle black. Individual generations are numbered with Roman numerals on the left of each pedigree. Individuals tested for the nucleotide substitution in each family are indicated either M (mutant allele) or M/N (mutant and normal allele). The genotypes of some females tested have not been shown due to privacy issues. * Figure 2: IQSEC2 structure and mutations. () Scheme of the human IQSEC2 protein (NP_001104595); shown are the IQ-like domain, Sec7 domain, pleckstrin homology domain (PH) and PDZ binding motif (UniprotKB/Swiss-Prot for Q5J85;1,488-amino-acid protein). Mutations in each family are shown above. () Missense mutations introduced into the Sec7 domain (light gray) diminish the GTP binding activity compared to the Sec7 wild-type (black) activity to levels seen with the E849A dominant negative mutant (dark gray) predicted to reduce GEF activity of the Sec7 domain. An all-groups comparison of the mean pMol of GTP bound to ARF6 was achieved by linear mixed model analysis. *P < 0.0001 compared to Sec7Wt. () Wild-type (Wt) ARF6-HA and Flag-tagged wild-type or mutant IQSEC2 were transfected into HEK293 cells and lysates were subjected to a pull-down assay with GST:GGA3 to isolate ARF6-GTP. The precipitates (above, top row) and lysates (above, bottom row) were probed with anti-HA to detect ARF6 and anti-Flag to detect expression ! of IQSEC2 (above, middle row). ARF6-GTP levels were normalized to total ARF6 levels and shown as the fold-increase over ARF6 transfected with empty vector. The E849K dominant negative mutation abolishes GEF activity of the Sec 7 domain8. Data are mean ± s.e.m. from three independent experiments (bottom panel). () The IQ-like motif sequence lacks the G and second basic residue of the IQ motif. Characters within parentheses can substitute for each other. The R359C mutation disrupts the basic (R) residue (in bold and boxed).

We sequenced the genomes of 21 strains representative of the global diversity and six major lineages of the M. tuberculosis complex (MTBC) at 40- to 90-fold coverage using Illumina next-generation DNA sequencing. We constructed a genome-wide phylogeny based on these genome sequences. Comparative analyses of the sequences showed, as expected, that essential genes in MTBC were more evolutionarily conserved than nonessential genes. Notably, however, most of the 491 experimentally confirmed human T cell epitopes showed little sequence variation and had a lower ratio of nonsynonymous to synonymous changes than seen in essential and nonessential genes. We confirmed these findings in an additional data set consisting of 16 antigens in 99 MTBC strains. These findings are consistent with strong purifying selection acting on these epitopes, implying that MTBC might benefit f! rom recognition by human T cells.

The tree is rooted with M. canettii, the closest known outgroup. Node support after 1,000 bootstrap replications is indicated. Branches are colored according to the six main phylogeographic lineages of MTBC defined previously3, 7, 8. Highly congruent topologies were obtained by maximum likelihood and Bayesian inference (Supplementary Fig. 1). * Figure 2: Average gene-by-gene nucleotide diversity across three gene classes. Box plot indicates median (horizontal line), interquartile range (box) and minimum and maximum values (whiskers). * Figure 3: dN/dS in various gene classes of MTBC. We calculated overall dN/dS on the basis of the number of nonredundant synonymous and nonsynonymous changes after comparing each of the 21 MTBC genomes to the inferred most likely recent common ancestor of MTBC. This shows that essential genes are more conserved than nonessential genes and that antigens are as conserved as essential genes. Figures for the epitope and non-epitope regions refer to the calculations after we excluded the three outlier antigens esxH, pstS1 and Rv1986. * Figure 4: Number of variable amino acid positions in 491 human T cell epitopes of MTBC. This demonstrates the remarkable lack of genetic variability among the regions of the genome that interact with the human immune system.

To identify common breast cancer susceptibility alleles, we conducted a genome-wide association study in which 582,886 SNPs were genotyped in 3,659 cases with a family history of the disease and 4,897 controls. Promising associations were evaluated in a second stage, comprising 12,576 cases and 12,223 controls. We identified five new susceptibility loci, on chromosomes 9, 10 and 11 (P = 4.6 × 10−7 to P = 3.2 × 10−15). We also identified SNPs in the 6q25.1 (rs3757318, P = 2.9 × 10−6), 8q24 (rs1562430, P = 5.8 × 10−7) and LSP1 (rs909116, P = 7.3 × 10−7) regions that showed more significant association with risk than those reported previously. Previously identified breast cancer susceptibility loci were also found to show larger effect sizes in this study of familial breast cancer cases than in previous population-based studies, consistent with polygenic susceptibility to the disease.

autoantibody-positive individuals with rheumatoid arthritis (cases) and 20,169 controls of European descent, followed by replication in an independent set of 6,768 rheumatoid arthritis cases and 8,806 controls. Of 34 SNPs selected for replication, 7 new rheumatoid arthritis risk alleles were identified at genome-wide significance (P < 5 × 10−8) in an analysis of all 41,282 samples. The associated SNPs are near genes of known immune function, including IL6ST, SPRED2, RBPJ, CCR6, IRF5 and PXK. We also refined associations at two established rheumatoid arthritis risk loci (IL2RA and CCL21) and confirmed the association at AFF3. These new associations bring the total number of confirmed rheumatoid arthritis risk loci to 31 among individuals of European ancestry. An additional 11 SNPs replicated at P < 0.05, many of which are validated autoimmune r! isk alleles, suggesting that most represent genuine rheumatoid arthritis risk alleles. View full text Figures at a glance * Figure 1: Associations with rheumatoid arthritis risk across four loci. Regional association plots show strength of association (−log10(P)) versus chromosomal position (kb) for all SNPs across 1 Mb regions centered on the newly validated SNPs (labeled). PGWAS values are plotted with diamonds for all SNPs, shaded white to red by the degree of LD (r2; see inset) with the validated SNP (larger red diamond). Poverall in combined analysis of GWAS and replication collections is plotted with a blue diamond. Local recombination rates estimated from HapMap CEU (cM/Mb, blue line) are plotted against the secondary y axis, showing recombination hotspots across the region.

() 10p15, IL2RA locus. * Figure 2: Previously validated autoimmune SNPs tested in our replication study. Eighteen SNPs tested in our replication samples were in LD (defined as r2 > 0.3) with a validated autoimmune risk allele. Of these, five were validated as rheumatoid arthritis risk alleles in our study (Poverall < 5 × 10−8, inner most circle), six were suggestive associations (Preplication < 0.05 but Poverall > 5 × 10−8) and six demonstrated no evidence of association in our replication samples (Preplication ≥ 0.05). For the 12 SNPs with suggestive or no evidence of association, each SNP is plotted by the strength of association with rheumatoid arthritis risk in the replication samples; those closer to the inner circle have more significant Preplication. All of the rheumatoid arthritis risk alleles confer risk in the same direction as the validated autoimmune risk alleles (when the same allele or a near perfect proxy was tested). We include the following as 'autoimmune' diseases in our study, listed on the outside of the circle, although these reflect diseases along ! the autoimmune-inflammatory spectrum: systemic lupus erythematosus (SLE), celiac disease, Crohn's disease, multiple sclerosis (MS), psoriasis, and type 1 diabetes (T1D) but other autoimmune diseases are not included (for example, autoimmune thyroiditis). Note that there are SNPs associated with rheumatoid arthritis and other autoimmune diseases not shown; we only include those SNPs tested as part of the current study. See Online Methods for details about the SNPs validated in other autoimmune diseases.

Here, through a genome-wide association study of rheumatoid arthritis, we identified a polymorphism in CCR6, the gene encoding chemokine (C-C motif) receptor 6 (a surface marker for Th17 cells) at 6q27, that was associated with rheumatoid arthritis susceptibility and was validated in two independent replication cohorts from Japan (rs3093024, a total of 7,069 individuals with rheumatoid arthritis (cases) and 20,727 controls, overall odds ratio = 1.19, P = 7.7 × 10−19). We identified a triallelic dinucleotide polymorphism of CCR6 (CCR6DNP) in strong linkage disequilibrium with rs3093024 that showed effects on gene transcription. The CCR6DNP genotype was correlated with the expression level of CCR6 and was associated with the presence of interleukin-17 (IL-17) in the sera of subjects with rheumatoid arthritis. Moreover, CCR6DNP was associated with susceptibility to Graves' and Crohn's diseas! es. These results suggest that CCR6 is critically involved in IL-17–driven autoimmunity in human diseases.

To identify additional susceptibility genes, we performed a genome-wide association study in 750 individuals with PDB (cases) without SQSTM1 mutations and 1,002 controls and identified three candidate disease loci, which were then replicated in an independent set of 500 cases and 535 controls. The strongest signal was with rs484959 on 1p13 near the CSF1 gene (P = 5.38 × 10−24). Significant associations were also observed with rs1561570 on 10p13 within the OPTN gene (P = 6.09 × 10−13) and with rs3018362 on 18q21 near the TNFRSF11A gene (P = 5.27 × 10−13). These studies provide new insights into the pathogenesis of PDB and identify OPTN, CSF1 and TNFRSF11A as candidate genes for disease susceptibility.

SNPs near two genes not previously associated with cleft lip with and without cleft palate (MAFB, most significant SNP rs13041247, with odds ratio (OR) per minor allele = 0.704, 95% CI 0.635–0.778, P = 1.44 × 10−11; and ABCA4, most significant SNP rs560426, with OR = 1.432, 95% CI 1.292–1.587, P = 5.01 × 10−12) and two previously identified regions (at chromosome 8q24 and IRF6) attained genome-wide significance. Stratifying trios into European and Asian ancestry groups revealed differences in statistical significance, although estimated effect sizes remained similar. Replication studies from several populations showed confirming evidence, with families of European ancestry giving stronger evidence for markers in 8q24, whereas Asian families showed stronger evidence for association with MAFB and ABCA4. Expression studies support a role for MAFB in palatal devel! opment.

In agreement with its role in the regulation of the immune system, PTPN2 was identified as a susceptibility locus for autoimmune diseases4, 5. In this work, we describe the identification of focal deletions of PTPN2 in human T-cell acute lymphoblastic leukemia (T-ALL). Deletion of PTPN2 was specifically found in T-ALLs with aberrant expression of the TLX1 transcription factor oncogene6, including four cases also expressing the NUP214-ABL1 tyrosine kinase7. Knockdown of PTPN2 increased the proliferation and cytokine sensitivity of T-ALL cells. In addition, PTPN2 was identified as a negative regulator of NUP214-ABL1 kinase activity. Our study provides genetic and functional evidence for a tumor suppressor role of PTPN2 and suggests that expression of PTPN2 ! may modulate response to treatment.

() Agilent array CGH and Affymetrix SNP array data for 13 T-ALL individuals indicating biallelic deletion of PTPN2 in individuals 1 to 7, and monoallelic deletion of PTPN2 in individuals 18, 20 and 22. *Blast cell content for individual 5 was only 50%. () Interphase FISH confirmed the presence of PTPN2 deletion in >90% of the cells for individuals 1 (biallelic deletion) and 20 (monoallelic deletion). () Quantitative PCR analysis on genomic DNA isolated from diagnosis, remission and relapse samples of individual 1 confirmed that the deletion was acquired at diagnosis, and again present at relapse. A primer set for CDH2 (18q12) was used for normalization. () PTPN2 expression was analyzed in a set from individuals with T-ALL (n = 90) using Affymetrix gene expression arrays (probe set 213136_at) and categorized according to oncogenic T-ALL subtypes (x axis). y axis displays PTPN2 expression as a logarithmic scale. n indicates number of affected individuals analyzed. () Quantitat! ive real-time PCR analysis of individuals with T-ALL detects lower expression for T-ALL cases with loss of PTPN2 as compared with affected individuals with no deletion. Expression values were normalized for HPRT gene expression and blotted at the y axis in logarithmic scale. Samples derived from bone marrow or peripheral blood were analyzed separately. Closed rectangles, no deletion (n = 8); open triangles, monoallelic deletion (n = 5); open circle, biallelic deletion (individual 1). The individual with an additional mutation in PTPN2 is shown in red. * Figure 2: Knockdown of PTPN2 causes higher sensitivity of T-cell lines to cytokine stimulation. () Protein blot analysis of whole-cell lysates showing higher sensitivity of JURKAT cells to cytokine stimulation (IFN-γ) due to decreased PTPN2 expression. Stimulated cells expressing reduced amounts of PTPN2 displayed an increased and prolonged phosphorylation of STAT1 as well as JAK1. Results of two independent experiments are shown. ERK1/2 was used as loading control. Open bars, siRNA PTPN2; closed bars, siRNA control. Bars show average ± s.e.m., n = 3; error bars represent s.e.m. *P < 0.005. () HPB-ALL cells expressing reduced (siRNA PTPN2) or normal amounts (siRNA control) of PTPN2 were stimulated with different concentrations of IL-7 for indicated time points and whole-cell lysates were analyzed for activation of STAT5 and JAK1 by protein blot. Quantification of protein blot experiments showed that knockdown of PTPN2 resulted in stronger activation of JAK1 and STAT5. Normalized quantification values calculated as relative change compared to unstimulated cells are sh! own below respective immunoblots. ERK1/2 was used as loading control. * Figure 3: Mouse T-ALL cells display altered cytokine receptor signaling in correlation with Ptpn2 expression. () Knockdown of Ptpn2 enhanced responsiveness of the IL-7 receptor pathway to ligand stimulation as displayed by increased strength and duration of the phosphorylation status of JAK1 and downstream protein STAT5 when compared with control cells. Open arrow points at the protein band corresponding to JAK1. Black arrow indicates time point of cytokine removal. STAT5 was used as loading control. () Protein blot analysis of whole-cell lysates showed increased sensitivity of primary mouse T-ALL cells to IL-2 stimulation due to decreased Ptpn2 expression as analyzed by phosphorylation level of STAT5. STAT5 is shown as loading control. () Cytokine-depleted cells were exposed to IFN-γ for indicated time periods and subsequently analyzed for activation of STAT1 by protein blot. Quantification of protein blot experiments showed that reduction of Ptpn2 protein resulted in stronger activation of STAT1. STAT1 was assayed to ensure equal protein loading. () Primary T-ALL cells were depri! ved of cytokines for 24 h before restimulation with either IL-7 alone or a combination of IL-2 and IL-7. Under both conditions, knockdown of Ptpn2 provided cells with a significant proliferative advantage in response to cytokine readdition. Open bars, shRNA Ptpn2; closed bars, shRNA Alk (control). Bars show average ± s.e.m. Error bars represent s.e.m. *P < 0.05. Efficient knockdown of Ptpn2 was confirmed using antibody to Ptpn2 (3E2). Differences in phosphorylation signal intensity were quantified for JAK1 and STAT proteins, and corresponding values are shown below blots. * Figure 4: Identification of NUP214-ABL1 oncogene as a new substrate of PTPN2. () Desphosphorylation of NUP214-ABL1 was observed upon overexpression of wild-type PTPN2 (PTPN2-WT). Immune precipitation (IP) of the catalytic mutant PTPN2-D182A resulted in coprecipitation of NUP214-ABL1. DD, destabilization domain; GFP, green fluorescent protein; WCL, whole-cell lysates. () Viable cell numbers determined 3 d after electroporation with small interfering RNAs (siRNAs). Decrease in PTPN2 resulted in proliferative advantage of ALL-SIL cells. () Cells were exposed to imatinib at time of maximal PTPN2 knockdown. Protein blot showed differential activation status of STAT family members downstream of NUP214-ABL1. ERK1/2 and an SRC-family kinase were constitutively active in ALL-SIL cells, and knockdown of PTPN2 caused an augmented phosphorylation, which stayed unchanged upon imatinib treatment. Loading control was ERK1/2. () IP experiments of ALL-SIL cells after electroporation with siRNAs showed an enhancing effect on JAK3 kinase activation (upper) and identifie! d the differentially activated SRC-family kinase as LCK. Phosphorylation of JAK3 and LCK were detected with a phosphotyrosine (pTyr) or phospho-SRC family antibody, respectively. JAK3 or LCK were used as loading controls. () Ba/F3 cells carrying indicated constructs were grown in the absence of IL-3, and mean growth ± s.e.m. was recorded in triplicate for 8 d. No s.e.m. is shown in case of values below 0.03. () Protein blot of NUP214-ABL1-dependent Ba/F3 cells demonstrated stronger constitutive activation of NUP214-ABL1 and STAT5 in case of concomitant shRNA-mediated knockdown of Ptpn2. Loading controls were c-ABL, STAT5. () Induced overexpression of PTPN2-WT in Ba/F3 cells carrying the NUP214-ABL fusion results in dephosphorylation of the oncogenic kinase and its downstream mediator STAT5. c-ABL is shown as loading control.

Hemoglobin binds and carries O2; however, its ability to offload O2 to respiring cells is hampered at low temperatures, as heme deoxygenation is inherently endothermic (that is, hemoglobin-O2 affinity increases as temperature decreases). We identify amino acid substitutions with large phenotypic effect on the chimeric β/δ-globin subunit of mammoth hemoglobin that provide a unique solution to this problem and thereby minimize energetically costly heat loss. This biochemical specialization may have been involved in the exploitation of high-latitude environments by this African-derived elephantid lineage during the Pleistocene period. This powerful new approach to directly analyze the genetic a! nd structural basis of physiological adaptations in an extinct species adds an important new dimension to the study of natural selection. View full text Figures at a glance * Figure 1: Evolution of the genes encoding the single adult-expressed hemoglobin component of three members of the Elephantidae family. The position of nucleotide and amino acid changes are shown within the three coding regions (exons) of the HBA-T2 and HBB/HBD globin genes (shown as open horizontal boxes along each branch) superimposed on the Elephantidae phylogeny4. Branch lengths are not proportional to geologic time. Ancestral nucleotide and amino acid residues are shown above, and derived nucleotide and amino acid residues are shown below the exons. The numbers above and the letters to the right of the vertical lines denote the amino acid residue, whereas the numbers below and the letters to the left of each vertical line indicate nucleotide position relative to the ATG initiation codon. Thick vertical lines with bold characters indicate nonsynonymous substitutions, and thin vertical lines represent synonymous substitutions, with red, green and blue characters and bars representing replacements at codon positions 1, 2 and 3, respectively. We employed the α-globin and β-globin chain sequences of other ! afrotherian mammals (Echinops telfairi (GenBank P24291, P24292), Procavia habessinica (P01957, P02086) and Trichechus inunguis (P07414, P07415)) to deduce the direction of amino acid substitutions. * Figure 2: Surface model of a chimeric Asian elephant (left) and mammoth (right) deoxyhemoglobin molecule bound to 2,3-bisphosphoglycerate (BPG). The locations of the three mammoth-specific amino acid substitutions are highlighted in blue, and the positions of each heme group are denoted by ball-and-stick diagrams. Regions highlighted in yellow denote positively charged residues (Lys82 of the β/δ-chain (hereafter denoted β/δ82 Lys), β/δ143 His and the amino group of β/δ1 Val) implicated in the binding of BPG to elephant deoxyhemoglobin11, 12, 14. Note that because the polar hydroxyl side chain of β/δ12 Thr of Asian elephant deoxyhemoglobin (and human hemoglobin25) forms a hydrogen bond with the carbonyl group of β/δ8 Lys (green), the negatively charged side chain of β/δ79 Asp (red) is free to project into the BPG binding pocket, where it would tend to repel this anion. Conversely, the methyl side chain of β/δ12 Ala in mammoth hemoglobin cannot bond with β/δ8 Lys, allowing the lysyl side chain to form an ionic interaction with β/δ79 Asp of the E helix and neutralizing its charge (light red). The mam! moth-specific β/δ101 Gln residue is spatially distant from this charged cluster and cannot contribute to BPG binding15, 16, 17. However, this central cavity residue alters electrostatic interactions at the sliding interface of the molecule that both destabilizes the low-affinity deoxy-state protein and creates additional proton-linked chloride binding sites in mammoth hemoglobin (see main text for details). * Figure 3: Oxygen equilibrium curves of woolly mammoth (blue) and Asian elephant hemoglobin (red) at 37 °C and pH 7.0. In the absence of allosteric effectors (solid lines), the mammoth β/δ-chain E101Q substitution destabilizes the tense-state (deoxy) conformation, leading to a protein phenotype with an intrinsic affinity nearly two times higher (curve is shifted to the left). This radical increase in O2 affinity (which would drastically impair tissue O2 offloading) is almost precisely compensated by enhanced H+, Cl− and 2,3-BPG binding to mammoth hemoglobin that right-shifts the curve more strongly than in Asian elephant hemoglobin. As a result, the overall O2 affinity of mammoth hemoglobin in the presence of red cell effectors is nearly identical to that of Asian elephants at 37 °C (red dashed line). However, the increased effector binding to mammoth hemoglobin lowers the effect of temperature on O2 affinity, facilitating the release of O2 at cold temperatures in relation to Asian elephant hemoglobin. * Figure 4: Mean enthalpy of oxygenation (ΔH; kJ mol−1 O2) values of woolly mammoth (blue columns) and Asian elephant (red columns) hemoglobin in the absence and presence of effector molecules. Error bars for each treatment ('stripped', 0.1 M Cl−, and 0.1 M Cl− plus saturating levels of 2,3-bisphosphoglycerate (Cl− + BPG)) are ± s.e.m. of four calculated ΔH values: one from O2 equilibria measured at 10 °C and 25 °C at pH 7.0; one from measurements at 25 °C and 37 °C at pH 7.0; one from measurements at 10 °C and 25 °C at pH 7.4; and one from measurements at 25 °C and 37 °C at pH 7.4. The temperature dependence of the oxygenation process is governed by the associated overall ΔH of this reaction19, where numerically low ΔH values correspond to small effects of temperature on hemoglobin-O2 affinity. Student's unpaired t-tests (α = 0.05, n = 4) illustrate that the intrinsic thermal sensitivity of mammoth hemoglobin is not different from that of Asian elephant hemoglobin (P = 0.9174). Conversely, as denoted by asterisks, the endothermic dissociation of Cl− (P = 0.0198) and BPG (P = 0.0168) each independently lower the oxygenation enthalpy of mammoth ! hemoglobin to significantly greater degrees than for Asian elephant hemoglobin, as predicted by the E101Q and T12A substitutions on the mammoth β/δ-globin chain, respectively (see text for details). The ΔH of mammoth hemoglobin was independent of pH under all conditions employed here, illustrating that the binding of Bohr protons does not directly contribute to lowering the ΔH value.

The development of new plant types, which is known as ideal plant architecture (IPA), has been proposed as a means to enhance rice yield potential over that of existing high-yield varieties1, 2. Here, we report the cloning and characterization of a semidominant quantitative trait locus, IPA1 (Ideal Plant Architecture 1), which profoundly changes rice plant architecture and substantially enhances rice grain yield. The IPA1 quantitative trait locus encodes OsSPL14 (SOUAMOSA PROMOTER BINDING PROTEIN-LIKE 14) and is regulated by microRNA (miRNA) OsmiR156 in vivo. We demonstrate that a point mutation in OsSPL14 perturbs OsmiR156-directed regulation of OsSPL14, generating an 'ideal' rice plant with a reduced tiller number, increased lodging resistance and enhanced grain yield. Our study suggests that OsSPL14 may help improve rice grain yield by facilitating the breeding of new elite rice varieties.

Here we show that the quantitative trait locus WFP (WEALTHY FARMER'S PANICLE) encodes OsSPL14 (SQUAMOSA PROMOTER BINDING PROTEIN-LIKE 14, also known as IPA1). Higher expression of OsSPL14 in the reproductive stage promotes panicle branching and higher grain yield in rice. OsSPL14 controls shoot branching in the vegetative stage and is affected by microRNA excision. We also demonstrate the feasibility of using the OsSLP14WFP allele to increase rice crop yield. Introduction of the high-yielding OsSPL14WFP allele into the standard rice variety Nipponbare resulted in increased rice production.
