Multiple sclerosis: heterology among early T cells and Tg cells

Abstract

Circulating early T cells and TG cells were estimated simultaneously in 100 patients with multiple sclerosis and 21 controls. The results were analyzed from individual patients, from patients grouped according to disease activity, and from some patients studied longitudinally. Previously documented fluctuations in these two T cell populations were confirmed. By comparing the fluctuations and by examining the distribution of TG cells in suspensions of isolated early and isolated late T cells, it was found that TG cells are a T cell subpopulation distinct from early T cells.
