Granzyme B expression by CD8+ T cells is required for the development of experimental cerebral malaria
Parasite burden predicts disease severity in malaria and risk of death in cerebral malaria patients. In murine experimental cerebral malaria (ECM), parasite burden and CD8+ T cells promote disease by mechanisms that are not fully understood. We found that the majority of brain-recruited CD8+ T cells expressed granzyme B (GzmB). Furthermore, gzmB-/- mice harbored reduced parasite numbers in the brain as a consequence of enhanced antiparasitic CD4+ T cell responses and were protected from ECM. We...[Show more]
