[Effect of "immune" RNA on various types of cells interacting in the immune response]
Simultaneous injection of marrow cells previously incubated with "immune" RNA, thymus cells and sheep red cells to X-ray treated mice resulted in a greater accumulation of antibody-forming cells in the spleen, as compared to mice inoculated with intact cells or with those incubated with normal RNA. Preliminary incubation of thymus cells with "immune" RNA did not affect the accumulation of antibody-forming cells. Incubation of peritoneal exudate cells with "immune" or normal RNA failed to influence the mode of accumulation of the antibody-forming cells either.
