Often cell death is brought on by cessation of its normal activities because of suppression by virus-specific proteins, not all of which are parts of the virus particle. Some viruses, similar to Epstein–Barr virus, may cause cells to proliferate without inflicting malignancy, while others, similar to papillomaviruses, are established causes of cancer. Attachment is a specific binding between viral capsid proteins and particular receptors on the host mobile surface. This specificity determines the host vary and sort of host cell of a virus.
This is because its surface protein, gp120, particularly interacts with the CD4 molecule—a chemokine receptor—which is mostly found on the floor of CD4+ T-Cells. This mechanism has evolved to favour these viruses that infect solely cells by which they are capable of replication.
