The Byrareddy lab research activities include understanding of host-virus dynamics, pathogenesis and prevention strategies of Human/Simian Immunodeficiency viruses (HIV/SIV) and other infectious diseases in general using Non-Human Primate models. We recently showed that by blocking of α4β7 integrin, using an antibody against α4β7 (a gut homing molecule) provided sustain virological control in SIV macaque models, emphasizing an importance of gut hemostasis in controlling infection. Current research includes evaluating connection of microbiome-gut-brain axis to understand host immune homeostasis and developing therapeutics for gut-brain disorders.
