Scientists at The Scripps Research Institute (TSRI) have solved the mystery of why a specific signalling pathway can be associated with alcohol dependence. This signalling pathway is regulated by a gene, called neurofibromatosis type 1 (Nf1), which TSRI scientists found is linked with excessive drinking in mice. The new research shows Nf1 regulates gamma-aminobutyric acid (GABA), a neurotransmitter that lowers anxiety and increases feelings of … Continue reading Scientists link alcohol-dependence gene to neurotransmitter.
