Research Focus

The Mankowski lab group studies the immunopathogenesis of HIV infection using the SIV/macaque model.

Pathogenesis of HIV-induced nervous system and cardiac disease processes

HIV is well known for its ability to induce loss of CD4+ T cells leading to immune suppression manifest as AIDS. HIV infection also causes debilitating disease in the brain, the peripheral nervous system, and in the heart secondary to infection of macrophages. Although virus-induced damage to these organs is common, the pathogenesis remains poorly defined.  Using the SIV/macaque model of HIV, we use a multidisciplinary approach to dissect the mechanisms underlying these diseases, including the central role of macrophage activation. 

Host genetics and lentiviral-induced CNS disease

The role that host genetics play in HIV-associated cognitive disorders is poorly understood.  We have identified a novel association between expression of a MHC class I allele in pigtailed macaques and SIV-induced CNS disease that sets the stage for studies defining how MHC class I-mediated control of SIV replication in the brain influences SIV CNS disease outcomes.
