Research Interest Summary
Research Interests
The Ambrose laboratory studies antiretroviral therapeutics used for HIV-1 prevention and suppression, including the characterization of new drug targets against early steps of the virus life cycle, and the impact of drug resistance on HIV-1 transmission, prevention, persistence, and treatment. To identify potential new therapeutic targets for HIV, we use genetics and microscopy assays to investigate host-virus interactions in early infection, including HIV capsid uncoating, reverse transcription and nuclear entry. The Ambrose lab has also studies SARS-CoV-2 replication and interaction with host cell pathways.
In addition, our lab studies novel drug candidates and sustained release therapies in vitro and in vivo for pre-exposure prophylaxis (PrEP) to prevent HIV-1 transmission as well as for antiretroviral treatment (ART) of HIV-infected individuals. We also investigate viral diversity that may impact co-infection with Mycobacterium tuberculosis or hepatitis B virus (HBV) and may lead to the development of HIV-1 drug resistance during PrEP or ART, which can impact subsequent or new therapy and the composition and persistence of tissue HIV-1 reservoirs.
