(16) It is suggested that the capacity of large doses of L3T4+ cells to protect mice against lethal GVHD is a reflection of T helper function: the cellular immunity provided by the donor L3T4+ cells enables the host to repel pathogens entering through damaged mucosal surfaces, with the result that GVHD becomes sublethal.
(17) Therefore, Leu 7+ (Leu 3+) germinal-center cells are distinct from "classic" T-helper cells of blood and lymphoid tissues.
