Research Interests

Dr. Johnson’s laboratory investigates the pathogenesis of feline immunodeficiency virus (FIV) infection of domestic cats.   FIV is a lentivirus that resembles HIV in virion structure and virus-host interaction. Members of the laboratory investigate issues relevant to pediatric HIV infection, including the influence of fetal infection on the ontogeny of the immune system, the role of the thymus in pediatric AIDS pathogenesis, and the development of novel therapeutic strategies to enhance thymus function.  Clinical research interests include immunopathology, infectious diseases, and lymphoma.
