Neuropeptide Y

Neuropeptide Y (NPY) is a small protein found in the brain and nervous system that plays a key role in various bodily functions. It helps regulate appetite, stress responses, and blood pressure. When you're hungry or stressed, NPY levels can increase, signaling your body to eat or cope with stress. It also influences social interactions and mood. Overall, NPY is important for maintaining balance in many physiological processes, impacting not just hunger and stress, but also overall emotional wellbeing. Its study is relevant for understanding conditions like obesity, anxiety, and other health issues.
