On the left, the HIV capsid is "naked," a state in which it would be easily detected by and removed from cells. However, as shown on the right, when the viral capsid binds to and is covered with a host protein, called cyclophilin A (shown in red), it evades detection and enters and invades the human cell to use it to establish an infection.
