Glucagon-like Peptide-1 Receptor Agonist Suppresses Muscle Inflammation and Muscle Fiber Death, and Ameliorates Muscle Weakness in Experimental Polymyositis
Background/Purpose: Glucocorticoids (GC) are the cornerstone of the treatment for polymyositis (PM). However, the treatment with GC causes GC-induced myopathy, which further deteriorates the muscle…Abstract Number: 1401 • ACR Convergence 2020
Disease Mutation That Weakens ZAP70 Autoinhibition Enhances Responses to Weak and Self Ligands
Background/Purpose: ZAP70, a cytoplasmic protein tyrosine kinase, is critical for TCR signaling and T cell development. Complete loss of function of ZAP70 in humans causes…Abstract Number: 1575 • ACR Convergence 2020
CD6 Is a Target for Cancer Immunotherapy
Background/Purpose: Limitations of checkpoint inhibitor immunotherapy include induction of autoimmune syndromes and resistance of many cancers. Definition of additional molecular targets is required. CD6, expressed…Abstract Number: 1905 • ACR Convergence 2020
Soluble Guanylate Cyclase Reduced the Gastrointestinal Fibrosis in Bleomycin-induced Mouse Model of Systemic Sclerosis
Background/Purpose: Systemic sclerosis (SSc) is a chronic autoimmune-mediated connective tissue disorder. Although the etiology of the disease remains undermined, SSc is characterized by fibrosis and…Abstract Number: 1912 • ACR Convergence 2020
Novel Role of Thy-1 (CD90) in the Pathogenesis of Skin Fibrosis
Background/Purpose: Thy-1 (CD90) is a GPI-anchored cell surface protein that is highly expressed in subsets of fibroblasts. Previous work has shown that Thy-1 deficiency exacerbates…Abstract Number: 1916 • ACR Convergence 2020
