Dual therapies, including protease inhibitor + maraviroc (MVC), may represent an alternative to traditional regimens for management of HIV infection. The aim of this in vitro study was to assess the effects of darunavir (DRV) alone or in combination with MVC on cell apoptosis and chemotaxis. A significant decrease of cell apoptosis was found after DRV treatment. The addition of MVC to DRV also had an in vitro down-regulating effect on cell migration. The combination of an NRTI-sparing regimen including DRV+ MVC may have a potential role in immune system modulation by the direct down regulation of apoptosis and chemotaxis.
