IL10 and malaria: Considering the fact that IL-10 may promote antiparasitic antibody production by B cells and may be detrimental for malaria pathogenesis and progression, our results of RNA expression of IL-10 in secondary lymphoid organs (lymph nodes and spleen) suggest the better expression of IL-10 in spleen with intramuscularly injected EL-PfMSP-Fu24 compared to the TD immunization of antigen.
