Ensuring transmission through dynamic host environments: host-pathogen interactions in Plasmodium sexual development.

Ensuring transmission through dynamic host environments: host-pathogen interactions in Plasmodium sexual development. Curr Opin Microbiol. 2015 Apr 7;26:17-23 Authors: Dantzler KW, Ravel DB, Brancucci NM, Marti M Abstract A renewed global commitment to malaria elimination lends urgency to understanding the biology of Plasmodium transmission stages. Recent progress toward uncovering the mechanisms underlying Plasmodium falciparum sexual differentiation and maturation reveals potential targets for transmission-blocking drugs and vaccines. The identification of parasite factors that alter sexual differentiation, including extracellular vesicles and a master transcriptional regulator, suggest that parasites make epigenetically controlled developmental decisions based on environmental cues. New insights into sexual development, especially host cell remodeling and sequestration in the bone marrow, highlight open questions regarding parasite homing to the tissue, transmigration across the vascular endothelium, and maturation in the parenchyma. Novel molecular and translational tools will provide further opportunities to define host-parasite interactions and design effective transmission-blocking therapeutics.
