Research Interests

Neuropathology; Retrovirology


Dr. Joseph L. Mankowski is a professor of molecular and comparative pathobiology, pathology and neurology at the Johns Hopkins University School of Medicine. His research focuses on the impact of HIV on the peripheral nervous system. His lab identified biomarkers that predict the onset of central nervous system disease arising from the simian immunodeficiency virus (SIV) and human immunodeficiency virus (HIV).

His team is studying the immunopathogenesis of HIV infection using the SIV/macaque model. They are using the SIV animal model to test the FDA-approved HIV drug maraviroc for its ability to reduce damage to the nerves and heart.

Dr. Mankowski received his undergraduate degree in neurobiology and behavior from Cornell University. He earned his D.V.M. from Cornell University and his Ph.D. in human genetics from the Johns Hopkins University. He completed a residency in pathology at Johns Hopkins and joined the Johns Hopkins faculty in 1996.

Dr. Mankowski provides diagnostic pathology support for the diverse animal species used in biomedical research at Johns Hopkins and is a diplomate of the American College of Veterinary Pathologists. more

Research Summary

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.
