Activation of invasion in Toxoplasma. Host cell invasion is critical for the establishment and maintenance of infection by the single-celled parasite Toxoplasma gondii, the causative agent of Toxoplasmosis. This project will use the latest molecular techniques to understand how invasion is activated and will define a new set of drug targets to treat Toxoplasmosis and related diseases.
Evolution of immunoregulatory networks: preventing autoimmunity at the expense of perpetuating chronicity in persistent infections. Chronic pathogens like HIV take advantage of human genes that regulate immune responses, which evolved to prevent autoimmunity, enabling them to evade eradication. This project defines the nature and interplays between these genes and will provide valuable clues as to how immunity can be manipulated to promote clearance of persistent infections.
