Multiparameter kinetic analysis of killer cell initiation by using immune RNAPJ Kmieck, CB Bagwell, JL Hudson and GL Irvin
By treating nonsensitized C57BL/6J spleen derived lymphocytes with EL-4 tumor cell directed xenogeneic extracted RNA we were able to monitor early changes in cellular DNA content by flow cytometric (FCM) analysis and 3H-thymidine uptake. These kinetic parameters were correlated with cell mediated cytotoxicity which appeared as early as 8 hr after activation as measured by release of chromium-51 from labeled EL-4 target cells. Flow cytometric analysis and 3H-thymidine uptake data shown peak S phase activity at 72 hr. Maximum cytotoxicity was observed at 48 hr. Cell cycle kinetic parameters were correlated with the appearance of cell mediated cytotoxicity.
