A protein in the brain that binds to alcohol could be the key to curing alcoholism, reports UH College of Pharmacy medicinal chemist Joydip Das in eNeuro, a journal of the Society for Neuroscience. The protein, called MUNC 13-1, plays a pivotal role in the development of tolerance to alcoholism according to Das.
“If a person becomes tolerant of one drink, he will have another and maybe another. If we could stop alcohol from binding into MUNC 13-1 it will help problem drinkers in reducing tolerance. If we can reduce tolerance we can reduce addiction,” said Das whose study focuses on binge alcohol exposure.
The process of MUNC 13-1 binding to alcohol takes place in a brain synapse, where one nerve cell, or neuron, passes a signal to another. Specifically, the binding takes place in the presynaptic space, a much understudied portion of the synapse mechanism.
During binge alcohol exposure, alcohol creates widespread and long-lasting changes in neural activity, altering both presynaptic and postsynaptic activity.
“Reduction in Dunc13 produces a behavioral and physiological resistance to sedative effects of ethanol,” said Das. That makes MUNC 13-1 an important target for developing drugs. “We need to develop a pill that would inhibit alcohol binding to MUNC 13 and reduce its activity. Based on our results so far, this would likely reduce the formation of tolerance, making it harder to become addicted to alcohol,” said Das.
