Entry Reverse transcription HIV dsDNA HIV ssRNA genome Integration Host genomic DNA Figure 1. HIV-1 Integrase: A New Drug Target For entry HIV binds to receptors (CD4; blue and CCR5 or CXCR4; green) and releases viral single-stranded RNA genome that is subsequently reverse transcribed to double-stranded DNA. Elvitegravir inhibits integrase that mediates an essential step, integration of HIV dsDNA into host genomic DNA.
