Title: Understanding the role of macrophages in the pathogenesis of cardiovascular disease in HIV/AIDS using the nonhuman primate model


Cardiovascular disease is a major cause of morbidity in HIV-infected individuals despite undergoing effective cART and appears to be associated with macrophage activation and inflammation. Using nonhuman primate models that simulate human disease, we previously reported that distinct lung macrophage populations play different roles in the pathogenesis of pulmonary disease during SIV infection in rhesus macaques.  Specifically, short-lived macrophages were more readily destroyed by SIV and contributed to AIDS pathogenesis.  Long-lived macrophages on the other hand were not easily destroyed by virus and thus may contribute to establishing a long-term virus reservoir and promoting chronic inflammation. Recent studies are extending this work to characterize the roles of macrophages in heart and skeletal muscles affecting the cardiomyopathy observed in SIV/HIV infection.
