We show here that a third family member, IMC1h, has a distinct differential expression pattern and localizes to the pellicle of both ookinetes and sporozoites. Knock-out of IMC1h mimics the loss-of-function phenotypes of IMC1a and IMC1b in their respective life stages, indicating that IMC1 proteins could be operating co-dependently.

We focus on three aspects of parasite cell biology: (i) plastid metabolism, (ii) sporozoite biology, and (iii) protein transport to and from the host erythrocyte. In each case recent work has led to a deeper understanding of parasite biology, often at the expense of previously accepted paradigms.

Rapid cell-mediated immune responses, characterized by production of proinflammatory cytokines, such as IFN-{gamma}, can inhibit intraerythrocytic replication of malaria parasites and thereby prevent onset of clinical malaria.
