Biochem/physiol Actions
NK-1 agonist; potent vasodilator and hypotensive agent; induces salivation; increases capillary permeability; induces mast cell degranulation; putative neurotransmitter in sensory (pain) afferents.
Substance P has proinflammatory effects on epithelial and immune cells. It has been associated with inflammatory diseases related to gastrointestinal and respiratory systems. Substance P modulates contractility of smooth muscles, transport of ions in the epithelium, vascular permeability and immune functions in the gut.
