The Altfeld laboratory studies innate and adaptive immune responses in viral infections.

The laboratory has four major areas of interest: a) The analysis of HIV-1-specific CD8+ T cell responses in Acute Infection, with particular focus on the mechanisms that determine the functionality and immunodominance of HIV-1-specific CD8+ T cell responses during the initial phase of HIV-1 infection. b) The analysis of Innate Immune Responses in HIV-1 infection, specifically focusing on the role of NK cells in HIV-1 infection and the impact of Toll-like Receptor (TLR) ligands on the function of NK and T cells. c) Thirdly, we are involved in monitoring changes in the HIV-1-specific T cell response in HIV-1-infected individuals undergoing therapeutic immunizations to understand the immune correlates of viral control. d) Finally, we are interested in characterizing the HIV-1 specific immune responses in populations of different ethnicities affected by the HIV-1 epidemic, and have close collaboration with the HIV-1 Pathogenesis Program at the Nelson Mandela School of Medicine at the University of KwaZulu-Natal in Durban, South Africa, the National Center for AIDS/STD Control and Prevention (NCAIDS) at the Chinese CDC in Beijing, and the Department of Infectious Diseases at the Tangdu Hospital in Xi’an, China.
