Role of the HPA Axis and the A118G Polymorphism of the {micro}-Opioid Receptor in Stress-Induced Drinking BehaviorAlcohol and Alcoholism 2009 44(4):358-365;
The results of the present study indicate that a blunted biological stress response was correlated with increased drinking in response to stress. The Asp40 variant of the ยต-opioid receptor may be associated with this HPA axis hyporeactivity although the small sample size used in the present study did not permit adequate evaluation of this association
