About David S. Peterson

he primary research focus of my laboratory is to understand the role of parasite adhesion proteins in the interaction of Plasmodium falciparum with receptors on host cells. The particular parasite proteins I am interested in are all members of the duffy binding-like (dbl) superfamily of adhesion proteins. Different members of this large family of related proteins have been demonstrated to play a central role in two critical events in the parasites life cycle: invasion of red blood cells and adherence of parasitized red blood cells to the vascular endothelium and to placental syncytiotrophoblasts. We are currently characterizing one putative erythrocyte binding protein, to determine its role in red cell invasion. Related work seeks to determine the degree of gene polymorphism and differences in gene expression in the erythrocyte binding protein family. ​

Recently we have also begun to test the expression of various Plasmodium proteins in a novel expression host, the free-living protozoan Tetrahymena thermophila. We have shown that proteins such as TRAP and the CSP can be expressed in Tetrahymena, and appear to be functional. We are now investigating the use of the Tetrahymena expression system for characterization of the erythrocyte binding protein family of Plasmodium falciparum.

Our lab is also part of a collaborative effort with the laboratory of Dr. Julie Moore in this department to study how the binding of parasitized erythrocytes to host cells effects host cell function, particularly as it relates to immune function.
