Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.HIV infects vital cells in the human immune system such as helper T cells (specifically CD4 + T cells), macrophages, and dendritic cells.nfection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk.

CD4 is a protein on the surface of the T cell. HIV's gp120 antigen is a mirror image of the CD4 protein. If HIV bumps into the right place on the T cell's surface, the gp120 of the virus will lock onto the CD4 site of the T cell (Figure 4). Because of this, CD4 is called the receptor site or docking port for HIV.
