ABSTRACT
A prominent role for the thymus gland in modulating the course of T-cell maturation has been well documented. Thymosin peptides have been reported to be responsible for part of this maturation process since they are able to restore partially symptoms of immunodeficiency resulting from congenital absence of the thymus gland (1). The immunoregulatory effects of both heterogeneous and purified thymosin preparations have also been described using a variety of animal models (2).
