In this article we will discuss about the working of immune system in the presence of HIV. Infection is carried out through the spicules present on envelope of HIV which attach to the target cell. The gpl20 has affinity for a specific molecule, the T4 or CD4 molecule exposed on the surface of certain cells i.e. lymphocytes. The lymphocytes secrete [...]
