Neurokinin-1

Neurokinin-1 (NK1) is a protein found on nerve cells that acts as a receptor for a molecule called Substance P. Substance P is involved in transmitting pain signals and regulating responses like inflammation and mood. When Substance P binds to NK1, it activates the nerve cell, influencing how we perceive pain and emotional responses. NK1 is also linked to conditions such as nausea, depression, and anxiety. Researchers are studying NK1 and Substance P to develop medications that can help manage these symptoms and improve treatments for related health issues.
