Comparative evaluation of the protective effect of immune spleen cells and immune RNA against Plasmodium berghei.
Earlier studies from this laboratory indicated that passive transfer of viable or frozen-thawed cells from spleens and lymph nodes of immune mice resulted in a significant protective immunity against Plasmodium berghei in syngeneic recipients. To assess whether immune RNA played a role in conferring such protection, experiments were designed wherein immune RNA was isolated from immune monkeys, rats and mice and transferred to normal mice. The effect of transfer was assessed by challenging RNA-primed animals with Plasmodium berghei. Results indicated that immune RNA failed to confer resistance against P. berghei both in syngeneic and in heterologous systems.
