Mice given injections of high antileukemic doses of cyclophosphamide lost the capacity to generate cytotoxic T-cells in vivo to allogeneic tumor cells. These low responses were not due to the elimination of cytotoxic T-lymphocyte precursors because normal cytotoxic responses were obtained in vivo after cyclophosphamide treatment by injection of helper factor derived from mixed-lymphocyte-cultur...
Cytotoxic T lymphocytes (CTLs) kill virus-infected cells and tumor cells, and play a critical role in immune protection. Our knowledge of how the CTL killing efficiency varies with CTL and target cell numbers is limited. Here, we simulate a region of lymphoid tissue using a cellular Potts model to characterize the functional response of CTL killing of target cells, and find that the total killi...
The studies reported herein were designed to determine the effects of allogeneic effect factor (AEF), a soluble mediator generated in the course of allogeneic cell interactions, on the differentiation of cytotoxic T lymphocytes in vitro. Normal, unprimed spleen cells from various strains of mice cultured with AEF for 5 days, in the absence of any stimulator cells, developed into cytotoxic lymph...
