Study reveals a small molecule inhibits SARS-CoV-2 infection in cells
Researchers Identify potent small molecule inhibitors against SARS-CoV-2
Research Interests
My research focuses on (a) understanding the molecular mechanism of host-pathogen interaction to develop therapeutic strategies against emerging and re-emerging viral diseases; (b) developing novel assays and tools to identify the location of the anatomical sanctuaries where HIV reservoirs persist and from where the virus rebounds to periphery upon cessation of combined antiretroviral therapy (cART); (c) using nonhuman primate models that mimic the biology of HIV infection to understand the role of the substance of abuse in seeding and maintenance of HIV reservoirs.
1) Understanding the role of substance use in HIV/SIV reservoirs
Substance use disorder (SUD) has been recognized as a prominent comorbidity in HIV-infected populations. The overall goal of this project is to understand the impact of SUD on HIV reservoir dynamics. We use non-human primate model of HIV infection to explore the molecular mechanism of HIV reservoir seeding and maintenance in presence of different substance of abuse.
2) Impact of HIV/SARS-CoV-2 co-infection.
The overall goal of the project is to understand the implications of COVID-19 on neuro-AIDS. We are interested to understand the pathophysiology of HIV/SARS-CoV-2 co-infection in the central nervous system. We will utilize a system biology approach that includes proteomic and transcriptomic analysis of HIV/SARS-CoV-2 co-infected cells from CNS.
