T cells following RAS immunization under CQ cover. Prior to RAS intradermal immunization with (RAS-CQ) or without chloroquine (RAS), mice received injection of SIINFEKL-specific CD8+ T cells. Ten days after a single immunization, expansion of CD45.1+CD8+ SIINFEKL-specific cells was determined in the liver and spleen of both immunized groups. NS= not significant.
