The detection of aberrant cells by natural killer (NK) cells is controlled by the integration of signals from activating and inhibitory ligands and from cytokines such as IL-15. We identified cytokine-inducible SH2-containing protein (CIS, encoded by Cish) as a critical negative regulator of IL-15 signaling in NK cells. Cish was rapidly induced in response to IL-15, and deletion of Cish rendered NK cells hypersensitive to IL-15, as evidenced by enhanced proliferation, survival, IFN-γ production and cytotoxicity toward tumors. This was associated with increased JAK-STAT signaling in NK cells in which Cish was deleted. Correspondingly, CIS interacted with the tyrosine kinase JAK1, inhibiting its enzymatic activity and targeting JAK for proteasomal degradation. Cish−/− mice were resistant to melanoma, prostate and breast cancer metastasis in vivo, and this was intrinsic to NK cell activity. Our data uncover a potent intracellular checkpoint in NK cell–mediated tumor immunity and suggest possibilities for new cancer immunotherapies directed at blocking CIS function.

The inhibitor of DNA binding 2 (Id2) is essential for natural killer (NK) cell development with its canonical role being to antagonize E-protein function and alternate lineage fate. Here we have identified a key role for Id2 in regulating interleukin-15 (IL-15) receptor signaling and homeostasis of NK cells by repressing multiple E-protein target genes including Socs3. Id2 deletion in mature NK cells was incompatible with their homeostasis due to impaired IL-15 receptor signaling and metabolic function and this could be rescued by strong IL-15 receptor stimulation or genetic ablation of Socs3. During NK cell maturation, we observed an inverse correlation between E-protein target genes and Id2. These results shift the current paradigm on the role of ID2, indicating that it is required not only to antagonize E-proteins during NK cell commitment, but constantly required to titrate E-protein activity to regulate NK cell fitness and responsiveness to IL-15.

The four mammalian SPRY (a sequence repeat in dual-specificity kinase splA and ryanodine receptors) domain-containing suppressor of cytokine signalling (SOCS) box proteins (SSB-1 to -4) are characterised by a C-terminal SOCS box and a central SPRY domain. The latter is a protein interaction module found in over 1600 proteins, with more than 70 encoded in the human genome. Here we report the crystal structure of the SPRY domain of murine SSB-2 and compare it with the SSB-2 solution structure and crystal structures of other B30.2/SPRY domain-containing family proteins. The structure is a bent beta-sandwich, consisting of two seven-stranded beta-sheets wrapped around a long loop that extends from the centre strands of the inner or concave beta-sheet; it closely matches those of GUSTAVUS and SSB-4. The structure is also similar to those of two recently determined Neuralized homology repeat (NHR) domains (also known as NEUZ domains), with detailed comparisons, suggesting that the NEUZ/NHR domains form a subclass of SPRY domains. The binding site on SSB-2 for the prostate apoptosis response-4 (Par-4) protein has been mapped in finer detail using mutational analyses. Moreover, SSB-1 was shown to have a Par-4 binding surface similar to that identified for SSB-2. Structural perturbations of SSB-2 induced by mutations affecting its interaction with Par-4 and/or c-Met have been characterised by NMR. These comparisons, in conjunction with previously published dynamics data from NMR relaxation studies and coarse-grained dynamics simulation using normal mode analysis, further refine our understanding of the structural basis for protein recognition of SPRY domain-containing proteins.

Background The molecular determinants of the severity and persistence of allergic asthma remain poorly understood. Suppressor of cytokine signalling 1 (SOCS1) is a negative regulator of IL‐4‐dependent pathways in vitro and might therefore control T‐helper type 2 (Th2) immunity associated traits, such as IgE levels, mucin production, IL‐5 and IL‐13 induction, and eosinophilic mucosal inflammation, which are implicated in allergic asthma.

The mammalian innate immune system has evolved to recognize foreign molecules derived from pathogens via the TLRs. TLR3 and TLR4 can signal via the TIR domain-containing adapter inducing IFN-β (TRIF), which results in the transcription of a small array of genes, including IFN-β. Inducible NO synthase (iNOS), which catalyzes the production of NO, is induced by a range of stimuli, including cytokines and microbes. NO is a potent source of reactive nitrogen species that play an important role in killing intracellular pathogens and forms a crucial component of host defense. We have recently identified iNOS as a target of the mammalian SPSB2 protein. The SOCS box is a peptide motif, which, in conjunction with elongins B and C, recruits cullin-5 and Rbx-2 to form an active E3 ubiquitin ligase complex. In this study, we show that SPSB1 is the only SPSB family member to be regulated by the same TLR pathways that induce iNOS expression and characterize the interaction between SPSB1 and iNOS. Through the use of SPSB1 transgenic mouse macrophages and short hairpin RNA knockdown of SPSB1, we show that SPSB1 controls both the induction of iNOS and the subsequent production of NO downstream of TLR3 and TLR4. Further, we demonstrate that regulation of iNOS by SPSB1 is dependent on the proteasome. These results suggest that SPSB1 acts through a negative-feedback loop that, together with SPSB2, controls the extent of iNOS induction and NO production.

Suppressor of Cytokine Signaling (SOCS)5 is thought to act as a tumour suppressor through negative regulation of JAK/STAT and epidermal growth factor (EGF) signaling. However, the mechanism/s by which SOCS5 acts on these two distinct pathways is unclear. We show for the first time that SOCS5 can interact directly with JAK via a unique, conserved region in its N-terminus, which we have termed the JAK interaction region (JIR). Co-expression of SOCS5 was able to specifically reduce JAK1 and JAK2 (but not JAK3 or TYK2) autophosphorylation and this function required both the conserved JIR and additional sequences within the long SOCS5 N-terminal region. We further demonstrate that SOCS5 can directly inhibit JAK1 kinase activity, although its mechanism of action appears distinct from that of SOCS1 and SOCS3. In addition, we identify phosphoTyr317 in Shc-1 as a high-affinity substrate for the SOCS5-SH2 domain and suggest that SOCS5 may negatively regulate EGF and growth factor-driven Shc-1 signaling by binding to this site. These findings suggest that different domains in SOCS5 contribute to two distinct mechanisms for regulation of cytokine and growth factor signaling.

Suppressor of cytokine signaling (SOCS) proteins are key regulators of innate and adaptive immunity. There is no described biological role for SOCS4, despite broad expression in the hematopoietic system. We demonstrate that mice lacking functional SOCS4 protein rapidly succumb to infection with a pathogenic H1N1 influenza virus (PR8) and are hypersusceptible to infection with the less virulent H3N2 (X31) strain. In SOCS4-deficient animals, this led to substantially greater weight loss, dysregulated pro-inflammatory cytokine and chemokine production in the lungs and delayed viral clearance. This was associated with impaired trafficking of influenza-specific CD8 T cells to the site of infection and linked to defects in T cell receptor activation. These results demonstrate that SOCS4 is a critical regulator of anti-viral immunity.

While it is known that the anti‐inflammatory effects of interleukin (IL)‐4 require new protein synthesis, the exact mechanisms by which IL‐4 suppresses the production of pro‐inflammatory cytokines by human monocytes and macrophages is unclear. IL‐4 rapidly induced suppressor of cytokine signalling‐1 (SOCS1) mRNA and protein, which peaked at 60 min, much earlier than lipopolysaccharide (LPS)‐induced SOCS1 mRNA and protein which were consistently maximal 4 hr post‐exposure. SOCS1 is a molecule generally considered to be induced for negative feedback of inflammatory processes. We investigated whether the early induction of SOCS1 by IL‐4 was responsible for the suppression of LPS‐induced tumour necrosis factor (TNF)‐α production by IL‐4. IL‐4 suppressed LPS‐induced TNF‐α in freshly isolated monocytes at the level of transcription but acted by a different, possibly translational, mechanism in monocytes cultured overnight in macrophage colony‐stimulating factor (M‐CSF). Despite different modes of regulation by IL‐4, the kinetics and magnitude of induction of SOCS1 mRNA and protein by IL‐4 in the two cell types were identical. There was no significant difference in the suppression by IL‐4 of LPS‐induced TNF‐α production by bone‐marrow derived macrophages from wild‐type mice, Ifnγ−/− mice and mice lacking SOCS1 (Socs1−/−Ifnγ−/−). These data suggest that SOCS1 is not involved in the suppression of LPS‐induced TNF‐α production by IL‐4.

Nicholson

Influenza virus infections have a significant impact on global human health. Individuals with suppressed immunity, or suffering from chronic inflammatory conditions such as COPD, are particularly susceptible to influenza. Here we show that suppressor of cytokine signaling (SOCS) five has a pivotal role in restricting influenza A virus in the airway epithelium, through the regulation of epidermal growth factor receptor (EGFR). Socs5-deficient mice exhibit heightened disease severity, with increased viral titres and weight loss. Socs5 levels were differentially regulated in response to distinct influenza viruses (H1N1, H3N2, H5N1 and H11N9) and were reduced in primary epithelial cells from COPD patients, again correlating with increased susceptibility to influenza. Importantly, restoration of SOCS5 levels restricted influenza virus infection, suggesting that manipulating SOCS5 expression and/or SOCS5 targets might be a novel therapeutic approach to influenza.

The anti-inflammatory actions of IL-4 in human monocytes are not mediated by IL-10, RP105 or the kinase activity of RIPK2

Eleanor A. Woodward; Tatiana B. Kolesnik; Sandra E. Nicholson; Cecilia M. Prêle; Prue H. Hart

The anti-inflammatory actions of IL-4 in activated human monocytes may reflect transcriptional regulation of genes involved in TLR signaling pathways. Tailored gene arrays were conducted to profile the expression of 84 genes central to TLR-mediated signal transduction in human monocytes treated with the TLR4 ligand, LPS, with or without IL-4. In the first 3h, IL-4 down-regulated mRNA levels of LPS-induced inflammatory cytokines and chemokines, without altering mRNA levels of TLRs, TLR-related signaling molecules or multiple transcription factors. The down-regulation of inflammatory genes by IL-4 was preceded by an early up-regulation of IL-10 mRNA and protein and mRNA for receptor-interacting serine-threonine kinase 2 (RIPK2), the TLR homolog, RP105, and c-Maf, a transcription factor required for IL-10 gene expression. However, IL-4 still suppressed LPS-induced TNFα production in bone-marrow derived macrophages from IL10(-/-) mice, and in the presence of a neutralizing antibody to IL-10 in human monocytes. The up-regulation of RIPK2 and RP105 mRNA by IL-4 occurred independently of IL-10. IL-4 maintained the ability to suppress LPS-induced TNFα and enhance IL-10 production in the presence of RIPK2 kinase inhibitors. Further, IL-4 failed to up-regulate expression of RP105 at the cell surface. In conclusion, the anti-inflammatory actions of IL-4 occur independently of IL-10, RP105, and the kinase activity of RIPK2.
