Human immunodeficiency virus type 1 (HIV-1) infection causes a progressive depletion of CD4 + T cells. Despite its importance for HIV-1 pathogenesis, the precise mechanisms underlying CD4 + T-cell depletion remain incompletely understood. Here we make the surprising observation that antibody-dependent cell-mediated cytotoxicity (ADCC) mediates the death of(More)
It has been known for more than 30 years that Human Immunodeficiency Virus 1 (HIV-1) infection drives a very potent B cell response resulting in the production of anti-HIV-1 antibodies targeting several viral proteins, particularly its envelope glycoproteins (Env) which are exposed at the surface of viral particles and infected cells [1]. Enthusiasm by the(More)
Binding to the primary receptor, CD4, triggers conformational changes in the metastable HIV-1 envelope glycoprotein (Env) trimer ((gp120-gp41)3) that are important for virus entry into host cells. These changes include an 'opening' of the trimer, creation of a binding site for the CCR5 co-receptor and formation and/or exposure of a gp41 coiled coil. Here we(More)
