摘要: The merozoite stage of the malaria parasite that infects erythrocytes and causes symptoms disease is initially formed inside host hepatocytes. However, mechanism by which hepatic merozoites reach blood vessels (sinusoids) in liver escape immune system before invading remains unknown. Here, we show parasites induce death detachment their hepatocytes, followed budding parasite-filled vesicles (merosomes) into sinusoid lumen. Parasites simultaneously inhibit exposure phosphatidylserine on outer leaflet plasma membranes, act as "eat me" signals to phagocytes. Thus, hepatocyte-derived merosomes appear ensure both migration bloodstream protection from immunity.
