Professional Interests
GENETIC ANALYSIS OF HOST-PARASITE INTERACTIONS
Our major research interests involve the molecular mechanisms of parasite pathogenesis. We focus on the protozoan parasites Toxoplasma gondii and Plasmodium falciparum. These apicomplexan parasites represent a paradigm of obligate intracellular infectious disease agents. Plasmodium falciparum causes a devastating form of human malaria which infects vast numbers of people and causes significant morbidity (adults and children) and mortality (mainly children). Toxoplasma gondii infection causes severe congenital defects in infants and death in HIV/AIDS patients. Current research projects include the following: developmental regulation of parasite virulence factors; identification of new parasite virulence determinants; development of new tools to facilitate genetic analysis of parasite pathogens; mechanisms, regulation and drug discovery in pyrimidine and purine acquisition pathways; design of vaccine components based on secreted antigens; novel parasite enzymes: mechanisms, regulation and drug discovery; creation and evaluation of live attenuated parasite vaccines; taming and targeting parasites for cancer gene therapy.

Protective efficacy of recombinant Toxoplasma gondii dense granule protein 15 against toxoplasmosis in C57BL/6 mice. From TgO/GABA-AT, GABA, and T-263 Mutant to Conception of Toxoplasma. Dense granule protein 3 of Toxoplasma gondii plays a crucial role in the capability of the tissue cysts of the parasite to persist in the presence of anti-cyst CD8(+) T cells during the chronic stage of infection. Cutting Edge: CD36 Mediates Phagocyte Tropism and Avirulence of Toxoplasma gondii. A Family of Toxoplasma gondii Genes Related to GRA12 Regulate Cyst Burdens and Cyst Reactivation. Toxoplasma gondii dense granule protein GRA24 drives MyD88-independent p38 MAPK activation, IL-12 production and induction of protective immunity. Succinylated Wheat Germ Agglutinin Colocalizes with the Toxoplasma gondii Cyst Wall Glycoprotein CST1. A simple and reliable method for determination of optimum pH in coupled enzyme assays. Toxoplasma gondii Parasitophorous Vacuole Membrane-Associated Dense Granule Proteins Regulate Maturation of the Cyst Wall. Toxoplasma gondii Intravacuolar-Network-Associated Dense Granule Proteins Regulate Maturation of the Cyst Matrix and Cyst Wall. |
