TL;DR: The finding that one chemokine receptor can function as a primary viral receptor strongly suggests that the HIV envelope glycoprotein contains a binding site for these proteins and that differences in the affinity and/or the availability of this site can extend the host range of these viruses to include a number of CD4-negative cell types.

TL;DR: This study reveals that by using appropriate screening methods, a large proportion of memory B cells can be isolated that produce mAbs with HIV-1 neutralizing activity, and three of these mAbs show unusual breadth of neutralization and therefore add to the current panel of HIV- 1 neutralizing antibodies with potential for passive protection and template-based vaccine design.

TL;DR: This review describes cell surface receptors, their roles in HIV entry and their influence on cell tropism.
