Uncovering the Brain Mechanism Behind Anxiety and OCD.

Scientists from the Universities of Bristol and Exeter have identified a gene in the brain that drives anxiety symptoms and demonstrated that modifying this gene can significantly reduce anxiety levels, presenting a potential new target for anxiety treatment. The gene, regulated by a molecule called miR483-5p, suppresses the expression of the Pgap2 gene, which controls stress-induced changes in the brain, and enhancing this pathway could lead to more potent and effective treatments for anxiety disorders.
