Animation showing HIV entering a human T cell. HIV (human immunodeficiency virus) is the virus that causes AIDS. Proteins on the surface of the virus (green) bind to CD4 receptors (blue) on the cell surface. After this, the viral envelope merges with the cell membrane, permitting the viral capsid (purple) to enter the cell. Once inside, the capsid releases the two strands of viral RNA (yellow). These are then transcribed to DNA for replication by the cell, which produces more viruses, and ultimately kills the cell. | |
