Two receptors, CD4 and a co-receptor act sequentially to trigger fusion of viral and cellular membranes and confer virus entry into cells. For HIV-1, the chemokine receptor CCR5 is the predominant co-receptor exploited for transmission and replication in vivo.
CD8 cells can recognize HIV antigen on CD4 cells as foreign, and will kill infected CD4 cells, adding to loss of these cells. HIV glycoprotein in the envelope is homologous to IL-2. Thus, HIV induces production of IL-2-neutralizing autoantibodies. These antibodies plus complement can kill IL-2-bearing cells.
