Attenuation of experimental autoimmune myositis by blocking ICOS-ICOS ligand interaction.
Polymyositis (PM) is an acquired, systemic, connective tissue disease characterized by the proximal muscle weakness and infiltration of mononuclear cells into the affected muscles. To understand its etiology and immunopathogenesis, appropriate animal model is required. It has been demonstrated that immunization with native human skeletal C protein induces severe and reproducible experimental au...
متن کاملUpregulated inducible co-stimulator (ICOS) and ICOS-ligand in inclusion body myositis muscle: significance for CD8+ T cell cytotoxicity.
Interactions between inducible co-stimulatory molecule (ICOS) and ICOS-ligand (ICOS-L) are crucial for T-cell co-stimulation, effector cell differentiation and memory CD8+ T-cell activation. Because in the muscle of patients with sporadic inclusion body myositis (sIBM) clonally expanded CD8+ T cells invade major histocompatibility complex (MHC) class I-expressing muscle fibres, we investigated ...
متن کاملDown-regulation of ICOS ligand by interaction with ICOS functions as a regulatory mechanism for immune responses.
Although it is well-known that the ICOS-ICOS ligand (ICOSL) costimulatory pathway is important for many immune responses, recent accumulated evidence suggests that dysregulation of this pathway may lead to and/or exaggerate autoimmune responses. ICOS is induced on the cell surface after T cell activation. Similarly, ICOSL is up-regulated on APCs by several mitogenic stimuli. However, the mechan...
متن کاملAbrogation of ICOS/ICOS ligand costimulation in NOD mice results in autoimmune deviation toward the neuromuscular system.
NOD mice spontaneously develop insulin-dependent diabetes around 10-40 wk of age. Numerous immune gene variants contribute to the autoimmune process. However, genes that direct the autoimmune response toward β cells remain ill defined. In this study, we provide evidence that the Icos and Icosl genes contribute to the diabetes process. Protection from diabetes in ICOS(-/-) and ICOSL(-/-) NOD mic...
