Decreased IFNβ levels in monocytes stimulated with acute alcohol and TLR8 or TLR4 ligand. Human monocytes (n = 3) were isolated as described in the methods. Cells were either treated or not with 25 mM ethanol or 2.5 ug/ml CL075 (TLR8 ligand) or 0.1 ug/ml LPS (TLR4 ligand) for 6 hours. Some cells were stimulated with a combination of 25 mM ethanol and 2.5 ug/ml CL075 or 25 mM ethanol and 0.1 ug/ml LPS. The cell-free supernatants were collected and IFNβ production was measured by ELISA. Error bars represent ± SEM. unst: unstimulated, ns: non significant.
