HIV infection cycle and break points, illustration
HIV infection cycle and break points. Illustration showing the retroviral process by which the human immunodeficiency virus (HIV) replicates, with 'banned' signposts indicating the points where the process can be disrupted. Incoming virus particles (upper left) attach to cell receptors and release their protein core through the cell membrane. The core (red) releases the RNA (ribonucleic acid, yellow) which is converted to DNA (deoxyribonucleic acid, red) by an enzyme (orange, lower left). The viral DNA enters the nucleus (bottom centre) and is added to the cell's DNA (blue) and used to make new RNA (red) that leaves the nucleus (lower right) and directs ribosomes to make new viral proteins (centre right). These make new virus particles (upper right) that bud out from the cell membrane. The three break points are: (1) preventing entry across the cell membrane; (2) preventing entry into the cell nucleus; and (3) preventing replication of the virus by the ribosomes.
