    These studies found that >95% of CD4 T cells die because of abortive HIV infection. [9] These dying cells are resting and thus are nonpermissive for productive HIV infection. Full viral replication was limited to the ~5% of activated CD4 T cells present in these tissues; these cells die by apoptosis. [10]

HIV-1 entry to macrophages and CD4 + T cells is mediated through interaction of the virion envelope glycoproteins (gp120) with the CD4 molecule on the target cells' membrane and also with chemokine co-receptors.
