Stress-induced anxiety is associated with increased activity of the protein Rap1 in the ventral hippocampus and can be prevented by injecting a Rap1 inhibitor, a new #ScienceAdvances study shows. scim.ag/3HQyymQ
scim.ag
Enhanced Rap1 small GTPase activity in the ventral hippocampus drives stress-induced anxiety
Chronic stress activates Rap1 in vHPC PNs to promote anxiety-like behaviors by increasing their intrinsic excitability.
