In addition to being an important receptor in leukocyte activation and mobilization, CCR5 is the essential coreceptor for human immunodeficiency virus (HIV). A large number of small-molecule CCR5 antagonists have been reported that show potent activities in blocking chemokine function and HIV entry. To facilitate the design and development of next generation CCR5 antagonists, docking models for...

PURPOSE Epstein-Barr virus (EBV) infects B cells, as well as T cells and natural killer (NK) cells, and is associated with T or NK cell lymphoid malignancies. In various tumor cells, mTOR performs an essential function together with Akt with regard to cell growth. We investigated the effects of mTOR inhibitors on EBV-associated T- and NK-cell lymphomas. EXPERIMENTAL DESIGN We investigated the...

BACKGROUND Changes in virulence during an epidemic are common among pathogens, but still unexplored in the case of HIV-1. Here we used primary human cells to study the replicative fitness of primary HIV-1 isolates from untreated patients, comparing historical (1986-1989) and recent samples (2002-2003). METHODS Head-to-head dual virus infection/competition assays were performed in both periphe...
