Abstract excerpt
The blood-stage merozoite surface protein 1 (PvMSP19) of Plasmodium vivax is a key target of naturally acquired antibodies. Effective humoral responses depend on T-cell co-stimulation, notably via the inducible co-stimulator (ICOS) molecule. Polymorphisms in the ICOS gene may influence antibody production, yet this relationship remains unexplored in naturally infected populations. We analysed 91 individuals with...
