Phytohemagglutinin-Induced Proliferation of Guinea Pig Thymus-Derived Lymphocytes

[摘要] Accessory cell participation in PHA-induced thymus-derived lymphocyte DNA synthesis encompasses two distinct functions. The first consists of maintenance of the functional integrity of resting lymphocytes, and the second involves the direct induction and/or support of T cell proliferation in response to this mitogen. Whereas the reducing agent 2-mercaptoethanol can support an Mø-depleted population of resting lymphocytes so that the latent biologic activity is maintained, it is not itself sufficient to allow the induction of lymphocyte proliferation in response to PHA. This latter function requires intact accessory cells.
