Lay Summary (English)

Lay summary
In the present proposal we aim to unravel mechanistic aspects of the humoral immune response in HIV infection to define if and which responses should be elicited by a successful vaccine regimen. We seek to define if neutralization of free virus is the sole effective antiviral activity of the humoral immune response in vivo or if antibodies against HIV also act through effector mechanisms of the immune system by inducing action of the complement system, killer cells or phagocytes. We will study how neutralizing antibodies mediate their antiviral activity in vivo, how they interfere with different modes of viral dissemination in tissue and which epitopes the neutralizing antibody response elicited in vivo recognizes. Lastly, we will investigate how virus escapes neutralizing antibodies and, in turn, the immune system adapts to the emerged viral variants to derive a more complete understanding of the interplay between virus and host immune system.
