Research
Molecular biology of the herpesviruses is under study to elucidate their mechanism of pathogenesis. Kaposi's sarcoma associated human herpesvirus (KSHV) or HHV-8 is a new herpesvirus implicated in the etiology of AIDS-related Kaposi's sarcoma, primary effusion lymphoma and multicentric Castleman's disease. KSHV produces several unique proteins that regulate cell cycle, signaling, angiogenesis and immune system. The molecular events in KSHV infection of target cells are under study to understand how KSHV manipulates the host cell for a successful infection. Studies in progress include: a) Defining the cell surface molecules recognized by KSHV and the role of viral envelope glycoproteins in the cell surface receptor interactions; B) Signaling pathways induced by KSHV during infection and their role in infection; C) Viral gene expression during infection; and D) Modulation of host cell genes by KSHV. These studies provide unique opportunity of utilizing cutting edge molecular and cell biological techniques to examine viral oncogenesis by integrating cell surface receptors, signaling molecules, cellular processes, cell cycle regulatory molecules, transcription factors, innate immune responses and angiogenic factors. A thorough understanding of KSHV pathogenesis from these studies will lead to novel methods to control KSHV infection. Dr. Chandran's research has been continuously funded by NIH and NCI. He is a member of the Editorial boards of the Journal of Virology and Human Virology. He has served as a member in NIH, MRC (UK) and other grant review panels. Currently, he is a regular member of the NIH-AIDS associated opportunistic infections and neoplasm study section.
