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.
HIV attaches to a cell. HIV empties its contents into the cell. The HIV genetic material (RNA) is used by the reverse transcriptase enzyme to build HIV DNA. The HIV DNA is inserted into the cell's chromosome by the HIV integrase enzyme. This establishes the HIV infection in the cell. When the infected cell reproduces, it activates the HIV DNA, which makes the raw material for new HIV viruses. Packets of material for a new virus come together.
