Cell Mediated Lysis of Lymphocytes Expressing Bacterial Antigens

Two T cell subpopulations are involved in the primary in vitro response to allogeneic cells. The cytotoxic T lymphocyte (Tc) recognizes HLA-A, B, and C antigens. However, the Tc is activated to kill only after collaboration with a second sub-population, the helper T cell (Th), which responds proliferatively to HLA-D antigens (1). We have asked whether purified protein derivative (PPD) and soluble Candida antigens (CAN) can substitute for foreign HLA-D in providing a helper interaction to alloreactive Tc.
