title: IL-13 restores an in vitro specific cytolytic response of spleen cells from tumor-bearing rats.
abstract: In a model of colon cancer, spleen cells from tumor-bearing rats are neither cytotoxic nor proliferative in vitro in the presence of tumor cells. Interleukin-13 (IL-13) induced an in vitro cytolytic activity of spleen cells from tumor-bearing rats in response to the tumor they bore, but had no effect on spleen cells from normal rats. This cytotoxic response was dependent on both adherent and non- adherent cells, involving both an antigen-presenting activity that was enhanced by IL-13 and a cytolytic activity of lymphocytes. So, IL-13 reversed the tumor-induced immunosuppression.
