CCR5 mediates Fas- and caspase-8 dependent apoptosis of both uninfected and HIV infected primary human CD4 T cells
CCR5 is ascribed to CCR5 a novel role in activating the Fas pathway and caspase-8 as well as triggering FasL production when activated by R5 Env, ultimately causing CD4 T cell death.

Giα protein-coupled chemokine receptors can function as death prone receptors and the balance between the above signaling pathways will ultimately mandate the fate of the activated cell.

It is suggested that activation of the chemokine receptor by HIVenv determines the mechanism of death for both infected and uninfected T lymphocytes.

HIV can directly cause hepatocyte death in humans by signaling through CXCR4, without infecting the cell.
Comparison of the metabolic effects of ritonavir-boosted darunavir or atazanavir versus raltegravir, and the impact of ritonavir plasma exposure: ACTG 5257.
Ritonavir C24 was not different in the PI arms and had no relationship with the modest but comparable increases in lipids observed with either atazanavir or darunavir, and raltegravir produced the most favorable lipid profile.

In these very advanced HIV-infected ARV-naive subjects, EFV-based highly active antiretroviral therapy had superior virologic efficacy than LPV/r-basedhighly active antifungal therapy, with a more favorable lipid profile.
