Question

Quizplus · Accepted Answer

HIV must bind both CD4 and a cytokine receptor to infect a cell. CD4 is a protein found on the surface of certain immune cells that helps in the recognition of foreign particles, while the cytokine receptor plays a crucial role in the communication between cells of the immune system. Binding both of these proteins allows HIV to enter the host cell and replicate. Factors such as the type of cytokine receptor can affect the efficiency of HIV infection.
