Monoclonal antibodies which block infectivity of malarial parasites to mosquitoes

摘要

Monoclonal antibodies have been developed that bind with one or more proteins located on the surface of gametes or zygotes of malaria parasites. These antibodies are specific for antigens on mosquito midgut stages of malaria parasite and sterilize the parasites in mosquitoes otherwise capable of transmitting the disease. The monoclonal antibodies are specific for the 255, 59 and 53 kilodalton surface proteins on Plasmodium falciparum and for the 25 kilodalton surface protein on zygotes and ookinetes of Plasmodium gallinaceum.
