Once the malaria parasite takes up residence in the hepatocyte, it transforms from its elongated sporozoite form to a rounded trophozite during a process called de-differentiation. After this process, the parasite undergoes rapid schizogony, replicating its DNA and producing tens of thousands of exo-erythrocytic merozoites within the confines of the PVM. Throughout this process, the parasite must regulate a variety of cellular processes, including the direct interaction with host structures and proteins. Host membranes and proteins are depicted in green, parasite structures and proteins in red and orange.
