Alcohol intake data have been previously reported [30, 36, 37]. The MS15 and MS360 groups did not differ in alcohol consumption although the propensity to increase alcohol intake over time and consume >1.5 g/kg/2 h was more evident in the MS360 group [37], as also reported in several studies [38]. Alcohol intake during the last week before sacrifice as well as the alcohol intake during the last week and last session was not correlated with Fkbp5 expression in any brain region or group.
