An experimental approach involves preventing the parasite from binding with red blood cells by blocking calcium signalling between the parasite and the host cell. Erythrocyte-binding-like proteins (EBLs) and reticulocyte-binding protein homologues (RHs) are both used by specialized P. falciparum organelles known as rhoptries and micronemes to bind with the host cell. Disrupting the binding process can stop the parasite.[3][4]
