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

ReviewModerate evidence
The takeaway

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.

Key finding

Amygdalar NPY-CRF interactions constitute an anxiety-resilience balance: CRF promotes fear/anxiety through CRF1 while NPY opposes through Y1 receptors

What the researchers 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.

Why it matters

Relevant for neuropeptides, anxiety-mood, addiction, receptor-signaling.
