title: Increased Fas antigen on T cells in multiple sclerosis.
abstract: Programmed cell death of antigen specific T cells (apoptosis) may be an important process in the pathogenesis of autoimmune diseases such as multiple sclerosis (MS). Fas antigen was recognized as an apoptosis-related antigen. To investigate Fas antigen in multiple sclerosis (MS), we measured the expression rate of Fas antigen and activation markers on T cells in peripheral blood (PB) of 19 MS patients, 18 controls and in cerebrospinal fluid (CSF) of nine MS patients by flow cytometry. The positive rate of Fas antigen in MS patients was higher than that of healthy controls in PB. In patients with MS, the expression rates of Fas antigen and activation markers were higher in CSF than in PB. The above findings suggest that there is acceleration or impairment of apoptosis on activated T cells in MS.
