AI-designed drug reduces fentanyl consumption in animal models by targeting serotonin receptors

AI-designed drug reduces fentanyl consumption in animal models by targeting serotonin receptors

A recent study published in the Proceedings of the National Academy of Sciences suggests that a novel drug developed using artificial intelligence can significantly reduce fentanyl consumption in animal models. The experimental medication targets specific serotonin receptors in the brain to restore neural pathways altered by addiction. These findings provide evidence that this new compound could eventually offer a non-addictive treatment option for people experiencing opioid use disorder. Opioid use disorder currently affects millions of people, with synthetic opioids like fentanyl driving a severe public health crisis. Seeking alternative treatments, scientists focused on creating a therapy that addresses the neurological changes caused by addiction without relying on opioid-based medications. “New therapeutics for opioid use disorder are desperately needed,” said study author Christie D. Fowler, a chancellor’s fellow and professor in the Department of Neurobiology and Behavior at the University of California, Irvine. “Just about everyone has been impacted by the opioid epidemic. These are people’s mothers, fathers, sisters, brothers, sons, and daughters.” Fowler, who also serves as the co-director of the UC Irvine Center for …

GLP-1 weight-loss drugs could help protect eyes from diabetic retinopathy

GLP-1 weight-loss drugs could help protect eyes from diabetic retinopathy

Sight can slip quietly in diabetes, often before you feel anything is wrong. The damage can start in the tiny blood vessels of the retina, the light-sensing tissue at the back of the eye. Over time, high blood sugar can weaken those vessels and harm the cells around them. That process can lead to diabetic retinopathy, a common complication that can steal vision. New research suggests a widely used class of diabetes and weight-loss drugs may help protect retinal cells from that damage, at least in early stages. The work will be presented at the annual meeting of the European Association for the Study of Diabetes in Vienna, Austria. The study focuses on GLP-1 receptor agonists, including semaglutide. These drugs mimic the action of GLP-1, a hormone that helps the body make more insulin when needed. They also slow digestion, curb appetite, and increase feelings of fullness. Scientists have also noted that many tissues have GLP-1 receptors, and recent research suggests the drugs may have anti-inflammatory and antioxidant effects. Assessment of cell viability.
