Researchers have identified two ion channel switches that regulate the release of dopamine in the brain, a first step that might one day lead to therapeutics for a wide range of diseases and disorders that currently have few solutions.
The switches help regulate learning and motivational state in mice. Humans also have hundreds of these channels, which govern many chemical and hormonal processes that influence behavior and mood. The University of Washington School of Medicine research team hopes to identify drugs to target these channels. Those drug candidates could then be tested in clinical trials.
“The ability to precisely manipulate how dopamine-producing neurons of the brain regulate different behaviors is a major step toward developing better therapies for a range of mental illnesses,” said Larry Zweifel, professor of psychiatry & behavioral sciences at the UW School of Medicine.
