To address this need, a high-throughput liver-stage malaria parasite assay was used to evaluate liver-stage activities of compounds comprising the TCAMS library, a malaria blood-stage parasite inhibitor collection of ∼14,000 compounds. The concentric double-membraned structures in plasmodium are derived from the plasma membrane. Introduction. Among the species that cause malaria in humans, Plasmodium falciparum (Pf) and P.vivax (Pv) are the most virulent and responsible for the majority of the mortality and morbidity attributed to malaria. Here we present the structure of a PIR protein, revealing the archi-tecture of its ectodomain and showing how it has diversified. An international research team led by scientists at the University of California, Riverside, and the La Jolla Institute for Immunology has found that malaria parasite genomes are shaped by parasite-specific gene families, and that this genome organization strongly correlates with the parasite’s virulence. Malaria Adhesins: Structure and Function Abstract. In the present study, we have investigated the malaria parasite enzyme diadenosine tetraphosphate (Ap4A) hydrolase that regulates levels of signalling molecules like Ap4A by hydrolyzing them to ATP and AMP.
