Question

What are the receptors of HIV?

A) CCR5 and CXCR4 B) CD4, CCR5, and CXCL4 C) CD4, CCR5, and CXCR4 D) CD4 and CCR4

Answer 1

Ans: Human immunodeficiency virus or HIV is the causative agent of AIDS (Acquired immunodeficiency syndrome). HIV infects and destroys a specific type of immune cells in the body called the helper T cells (TH cells). Helper T cells activates several other immune cells. HIV initiates infection by binding to receptors on the surface of the helper T cell: the CD4 receptor and the co-receptor CCR5 and fusin which is also known as CXCR4.

So, the correct alternative is option-C CD4, CCR5, and CXCR4.
