Cells participating in immunologic memory induced with RNA from the spleens of immunized mice.
Ribonucleic acid (immune RNA, iRNA) extracted from the spleens of mice immunized with heterologous red blood cells induced antigen-specific immunologic memory. The type of cells (T cells, B cells) which participate in immunologic memory induced with iRNA was investigated. Immune RNA-primed T cells cooperated with normal, iRNA-primed or antigen-primed B cells and induced a high IgM response. Immune RNA-primed B cells did not cooperate with normal T cells, but did with iRNA- or antigen-primed T cells. The activities of iRNA-primed T and B cells were antigen-specific.
