Molecular mechanisms contributing to addiction resistance uncovered

22 julio 2015

A genetic variant leading to a single change in the amino acid sequence of a cell surface protein, the mu-opioid receptor, is associated with lower susceptibility to a variety of addictive behaviors in humans, including smoking, alcoholism, and morphine abuse. A team of scientists reports evidence that the G allele in an analogous mouse model causes changes in hippocampal operation, and thus a ‘loss of function’ phenotype in the brain’s microcircuitry.img src=»http://feeds.feedburner.com/~r/sciencedaily/~4/VVYfJqrVMBg» height=»1″ width=»1″ alt=»»/
