Abstract

The effect of thymopentin (TP-5) treatment on lymphocyte immune functions has been investigated in immunocompromized aged subjects. TP-5 was able to improve the cutaneous delayed hypersensitivity (CDH) to recall antigens and the proliferative response to phytohemagglutinin (PHA), concanavalin A, and Pokeweed (PWM) as well as the PHA-induced interleukin-2 (Il-2) production. On the other hand, no detectable changes were induced by TP-5 treatment either on PWM-induced immunoglobulin synthesis or on lymphocyte subsets identified by monoclonal antibodies. Our results suggest that the enhancement of Il-2 synthesis might be a crucial mechanism of the immunopharmacological action of TP-5 in aging humans.
