Researching host-pathogen and drug-pathogen interactions to inform HIV treatment and curative strategies.

The Gupta lab has teams in both London and at the Africa Health Research Institute in Durban South Africa. Our work focuses on two areas:

  • Studying  HIV drug resistance to protease / integrase inhibitors and implications for global scale up of antiretroviral therapy.
  • Dissecting the biology of macrophage-virus interactions given myeloid cells are parasitised by HIV and are a difficult-to-treat reservoir.
