Original Article


A direct role for IgA either for elimination of malaria parasite or for improvement in tissue pathology has not been investigated in case of Malaria infection while IgG, IgE and IgM were all implicated in the adverse pathology. In this communication, we delineate further that Malaria specific IgA appears to be significant among individuals who had multiple episodes of infection. Interestingly, the IgA elicited by immunization of the homologous peptides derived from Plasmodium berghei ANKA have also resulted in protection of host from adverse lung pathology, while the parasite load is unaffected. The PfrVI immunized mice and mice infected with repeated cycles of ‘infection and recovery’, simulating an endemic like situation, have resulted in development of B cell population that secretes the IgA specific to this region VI. Summarily, our results suggest that the IgA specific to the malarial antigen can confer significant advantage to hosts in protecting the overall tissue pathology.
