Analysis Of Gene Expression In Mouse Brains During Toxoplasma Gondii Infection, Yi Zhou

Mahurin Honors College Capstone Experience/Thesis Projects

Previous studies in our laboratory have shown that dietary supplementation with antioxidants is harmful during murine infection with the protozoan parasite, Toxoplasma gondii, which causes toxoplasmosis in humans. Dietary supplementation with vitamin E and selenium was shown to increase tissue cyst number, tissue pathology, and weight loss during T. gondii infection. The goal of the present study was to determine the impact of diet on global gene expression in the brains of infected and non-infected mice and to identify the major genes that are differentially expressed, determine their function, and discover the molecular pathways in which these genes participate.
