CD4 and multiple sclerosis: Gene expression analysis of circulating naïve CD4+ T cells from 37 patients with the clinically isolated syndrome (CIS), an early form of multiple sclerosis [79] and overlapping with data set obtained from CD4+ T cells of chromosome Y-substituted mouse strains led to identifying 440 genes common between mouse and human which were involved in central dogma, providing further evidence of a profound effect Y chromosome on susceptibility to autoimmune disease [77].
