Association of apoptosis-related variants to malaria infection and parasite density in individuals from the Brazilian Amazon
Abstract Background In malaria infection, apoptosis acts as an important immunomodulatory mechanism that leads to the elimination of parasitized cells, thus reducing the parasite density and controlling immune cell populations. Here, it was investigated the association of INDEL variants in apoptotic...
