Although the mechanism of action of thymosin has yet to be definitively established, it is clear that thymosin can activate immature lymphoid cells and induce their differentiation into immunologically competent T-lymphocytes in vitro and in vivo (1–5). It appears that one subpopulation of T-cells, the so-called “suppressor” or “regulator” T-cells, may be dependent upon thymosin for their differentiation and perhaps maintenance as a cell population (2,3). In this paper we review the results of animal and clinical experimentation which support the hypothesis that an imbalance in thymosin production and/or secretion may be part of the pathological mechanisms in certain autoimmune diseases.This deficiency is thought to lead to inadequate production of subpopulations of T-cells, such as the suppressor or regulator cells which appear to exert, in as yet an undefined manner, fine control over the immune system.
