Immunity to the liver stage of malaria.
The search for subunit vaccines against malaria has concentrated on asexual and sexual blood stage and sporozoite antigens. In recent years the search for the basis of the protection against sporozoite challenge obtained in mice immunized with irradiated sporozoites has focused attention on the liver or exoerythrocytic (EE) stage of the malaria life cycle. Here, Andreas Suhrbier looks at the various immune responses that appear to be active against this stage, which was once thought to be immunologically insignificant. The liver stage of malaria has thus emerged as a legitimate target for vaccine development.
