TIGIT signalling pathway negatively regulates CD4+ T-cell responses in systemic lupus erythematosus.

Abstract excerpt

B-lymphocyte hyperactivity in systemic lupus erythematosus (SLE) is T-cell-dependent, and CD4+ T-cell activation is essential to SLE pathogenesis. However, the mechanism of the deregulation of CD4+ T cells in SLE is largely unknown. T-cell immunoglobulin and ITIM domain (TIGIT) is a new inhibitory receptor preferentially expressed on activated CD4+ T cells. Here, we address the role of TIGIT in the pathogenesis...
