NPY and CRF in the Amygdala: The Anxiety Balance Between Stress and Resilience

NPY and CRF interactions in the amygdala control the balance between anxiety and resilience, with CRF promoting fear/anxiety and NPY opposing it — disruption of this balance drives anxiety disorders and PTSD.

What This Study Found

Amygdalar NPY-CRF interactions constitute an anxiety-resilience balance: CRF promotes fear/anxiety through CRF1 while NPY opposes through Y1 receptors — imbalance drives anxiety disorders, PTSD, and addiction.
