Cellular basis of the proliferative response of human T cells to mouse xenoantigens
Purified human T cells respond proliferatively to allogenic peripheral blood mononuclear (PBMC) stimulating cells but show no response to murine splenic stimulating cells. Two possible explanations for the lack of xenogeneic response are that human T cells, educated in a human thymus, cannot directl...

description | Purified human T cells respond proliferatively to allogenic peripheral blood mononuclear (PBMC) stimulating cells but show no response to murine splenic stimulating cells. Two possible explanations for the lack of xenogeneic response are that human T cells, educated in a human thymus, cannot directly recognize a molecule as disparate as mouse antigen encoded by H-2 and/or that a cytokine(s) produced by the APCs is needed to allow a proliferative response and that the cytokine(s) produced by murine APC do not provide an adequate stimulus to the human T cells under these conditions. We show here that highly purified human T cells can respond directly in an antigen-specific manner to murine stimulating cells if human rIL-1 or rIL-2 or a T cell growth factor (TCGF) preparation are present in the culture. These findings demonstrate that human T cells can recognize murine antigens and that a highly significant response can be obtained if a human cytokine is present to permit that response. |
