The cellular basis of immunity to sporozoites was investigated by examining the effect of immunization of T and B cell-deficient C57BL/6N x BALB/c AnN F/sub 1/ (BLCF/sub 1/) mice compared to immunocompetent controls. Immunization of T cell-deficient (ATX-BM-ATS) BLCF/sub 1/ mice with x-irradiated sporozoites did not result in the generation of protective immunity. The same immunization protocols protected all immunocompetent controls. In contrast, B cell-deficient (..mu..-suppressed) BLCF/sub 1/ mice were protected by immunization in the majority of cases. The absence of detectable serum circumsporozoite precipitins or sporozoite neutralizing activity in the ..mu..-suppressed mice that resisted a sporozoite challenge suggests a minor role for these humoral factors in protection. These data demonstrate a preeminent role for T cells in the induction of protective immunity in BLCF/sub 1/ mice against a P. berghei sporozoite infection.
