AB Large amounts of human immunodeficiency virus (HIV) localize on
follicular dendritic cells (FDC) in the follicles of secondary lymphoid
tissues following viral infection. During clinical latency, active viral
infection occurs primarily at these sites. As HIV on FDC is in the form
of immune complexes, some of which may be formed with neutralizing
antibody, we investigated whether HIV on FDC is infectious. We report
here that HIV on FDC is highly infectious. Furthermore, FDC can convert
neutralized HIV into an infectious form even in the presence of a vast
excess of neutralizing antibody. Thus FDC may provide a mechanism
whereby HIV infection can continue in the presence of neutralizing
antibody.
