Dr. Giavedoni’s principal research interests include the study of viral infections and the development of vaccines against such infections. His laboratory specifically works in understanding the innate and adaptive immune responses to retroviral infections in animal models of natural and experimental infections, and in identifying correlates of vaccine-induced protection against infection with filoviruses. They study the role of cytokines and co-stimulatory proteins, molecules that mediate communication between the immune system and the whole organism. His laboratory has been developing reagents for the identification of cytokines in nonhuman primates (NHP) and also studying the potential use of these molecules to modify the outcome of immune responses. They have also studies aiming at controlling or eliminating the virus in NHP infected with retroviruses.

Dr. Giavedoni’s laboratory also serves as the Immunology Core Laboratory for the Southwest National Primate Research Center (SNPRC); The lab supports the work of other scientists by:

1) providing assays based in flow cytometry for the characterization and isolation of blood cell subsets and the determination of cell mediated activity (T-cell proliferation, cytotoxic and natural killer cell activity) in nonhuman primate species;

2) providing methodologies for the simultaneous determination of multiple cytokines and chemokines in biological fluids derived from nonhuman primate species; and

3) identifying certain herpes and retroviral infections in macaques from the SNPRC specific pathogen-free (SPF) Indian rhesus macaque breeding colony.
