TL;DR
Assessment of plasma NPY immunoreactivity in healthy soldiers participating in high intensity military training at the U.S. Army survival school provides evidence that uncontrollable stress significantly increases NPY in humans, and when extended, produces a significant depletion of NPY.
Abstract
These results provide evidence that uncontrollable stress significantly increases plasma NPY in humans, and when extended, produces a significant depletion of plasma NPY. Stress-induced alterations of plasma NPY were significantly different in Special Forces soldiers compared to non-Special Forces soldiers. These data support the idea that NPY may be involved in the enhanced stress resilience seen in humans.
