Position TitleAssociate Professor
Inflammation is an outcome of the host response to injury or infection. When occurs for a short duration (acute inflammation), it is beneficial to the host. However, inflammation that persists over a long period of time (chronic inflammation) is detrimental to the body. The research in Professor Suvas lab is focused to determine the relative contribution of peripheral nervous system (PNS) in regulating the corneal chronic inflammation induced in response to ocular herpes simplex virus-1 (HSV-1) infection. If left untreated, HSV-1 induced chronic inflammation can cause the development of herpetic stromal keratitis (HSK), a leading cause of infection induced blindness in the United States. The lab is also ascertaining the age-related alterations in PNS and its effect on the development of inflamaging (a low-grade systemic inflammation that develops with increasing age). Studies are also being carried out to determine the immunobiology of Foxp3 Tregs in aged host and their relative contribution in controlling inflamaging in the mouse model. The lab is currently funded with a R01 grant from National Eye Institute (NEI).

The Suvas laboratory studies the immunity and pathogenesis to herpes simplex virus-1 (HSV-1) infection. Recurrent corneal infection with HSV-1 causes herpes stromal keratitis (HSK), a major cause of infection-induced blindness in the United States and worldwide. HSK is an immunopathological condition, which causes scarring and angiogenesis of the infected cornea. Our lab employs a combination of flow cytometric, immunohistochemical, cellular and molecular biology based approaches to address the pathogenesis of corneal HSV-1 infection. We are currently using a mouse model of HSV-1 infection to understand the role of neuropeptides in regulating inflammation at the ocular surface system and in trigeminal ganglia during lytic and latent phase of infection. In addition, we are also studying the role of hypoxia inducible factors (HIFs) and its downstream target genes in the pathogenesis of HSK. By understanding factors involved in regulating chronic inflammation, we expect to contribute novel information to the better management of HSK.
