Abstract:
Abstract Nod2 is a pattern recognition receptor known for its role in antimicrobial immunity. Intriguingly, NOD2 appears to have a role outside of infection, as a single point mutation in this molecule leads to 100% incidence of an inflammatory arthritis called Blau Syndrome. Here we investigate the role of Nod2 in regulation of arthritogenic CD4+ T cells in SKG mice. SKG mice have a mutation in ZAP-70 that results in altered thymic selection and spontaneous production of arthritogenic T cells. Nod2−/− SKG mice have exacerbated arthritis and increased numbers of CD4+IL-17+ (Th17) cells that co

ObjectivesAxial spondyloarthritis (axSpA) is a chronic inflammatory condition mainly impacting the musculoskeletal system. The majority of axSpA patients experience gut inflammation, with 60% having microscopic changes and 10% having overt inflammatory bowel disease (IBD). Over the years, researchers have linked many pathways and cell populations to the pathogenesis of gut inflammation in axSpA. One notable player may be the macrophage migration inhibitory factor (MIF), a crucial factor in axSpA development. In a SpA mouse model (SKG mice), MIF overexpression mirrors key clinical features of a

Abstract Rheumatoid arthritis remains a major public health concern, estimated to affect 1.5 million adults in the U.S. However, the etiology and underlying immunological mechanisms of this disease remain largely speculative.

Arthritis in SKG mice replicates a current theoretical paradigm that environmental factors, including microbes, activate preexisting autoreactive T cells in genetically predisposed individuals to cause disease.

BackgroundSpondyloarthritis (SpA) is characterised by chronic debilitating axial and peripheral joint inflammation, often concomitant with inflammatory bowel disease (IBD)-like gut phenotypes. However, the contribution of extra-articular gut pathologies to SpA is not well understood. The ZAP-70W163CBALB/c (SKG) mouse model of SpA develop chronic arthritis, spondylitis and IBD-like ileitis commencing from 1 week after intraperitoneal curdlan injection with characteristic interleukin-23-dependent gut dysbiosis, endoplasmic reticulum (ER) stress and goblet cell depletion.

ObjectivesAnkylosing spondylitis (AS) is a highly heritable immune-mediated arthropathy. Inflammation in AS is poorly understood. TBX21 encodes T-bet, a transcription factor, lying within a locus with genome-wide significant association with AS. T-bet is implicated in innate and adaptive immunity. However, the role of T-bet in AS pathogenesis is unclear.MethodsWe assessed the importance of T-bet in disease development and progression in peripheral blood mononuclear cells from 172 AS cases and 83 healthy controls carrying either risk or protective alleles of the peak AS-associated TBX21 single

Abstract We recently discovered a role for Nod2 within T cells in controlling Th17-immunity, such that deletion of Nod2 exacerbated experimental autoimmune arthritis and uveitis. Protection against opportunistic Candida albicans infection relies on intact Th17-responses. Thus, we considered whether the T cell intrinsic Nod2 might control antifungal Th17 responses at the cost of increasing host susceptibility to autoimmunity. Nod2−/− mice infected with 105 (LD50) Candida albicans had increased survival and reduced fungal burden in the kidney within 24–72 h post-infection, suggesting a critical

Abstract:
Abstract Rheumatoid arthritis (RA) is a chronic autoimmune disease that often leads to joint damage. The etiology of RA remains unclear, but new insights and therapeutic strategies have been facilitated by murine models. In the K/BxN serum transfer (STA) model, arthritis is triggered by autoantibodies against glucose-6-phosphate isomerase. The SKG model has a ZAP70 point mutation that reduces TCR signaling. After zymosan exposure, SKG mice develop arthritis, mediated by autoreactive Th17 cells. Joint inflammation in these models shares many features with RA, including leukocyte invasion, synov

To counter differences in hardware and noise conditions at the legitimate nodes, which can lead to key mismatch, the SKG algorithms typically include the intermediate steps of sampling, quantization, information reconciliation, and privacy amplification.

Abstract ZAP-70, a Syk family protein tyrosine kinase, is critical for efficient signaling downstream of the TCR. Our lab and others have previously shown that tyrosine 315 and 319 in the interdomain B positively regulate ZAP-70 function by recruiting Vav1 and Lck, respectively. Surprisingly, in addition to their scaffolding function, we recently discovered that Y315 and Y319 play an important role in the autoinhibition ZAP-70 kinase activity. To address the relative importance of the scaffolding function of these residues versus their autoinhibition function, we generated a knock-in ZAP-70 mu
