Molecular function of the CD4 D1 domain in coreceptor-mediated entry by HIV type 1.

abstract：:Lentivirus infections are characterized by a dramatic loss of mucosal CD4(+) T cells, breakdown of the gut mucosa, and subsequent chronic immune activation. Residual immune activation persists even in patients controlling virus replication and remains a significant source of ongoing disease morbidities, but the causes...
