Substance P
Test Summary
Substance P is a neuropeptide present in the central and peripheral nervous system. Substance P is a neurotransmitter released in response to pain and other noxious stimuli. Substance P is a neuropeptide of the tachykinin class that also includes neurokinin. Substance P is found in the brain, spinal cored, and peripheral tissues and is released from nerve endings in response to stimuli. Increased substance P levels can occur in neurogenic inflammation and physiological stress and may be associated with carcinoid or neuroendocrine tumors.
