Immunopharmacology Ligand
Comment: MET-enkephalin (MENK) is an endogenous opioid peptide. It exhibits agonist activity at the δ- and μ-opioid receptors. MENK produces immunomodulatory, neuromodulatory, antinociceptive/analgesic, antidepressant, and gastrointestinal motility modulating activities. It has cytostatic activity vs. cancer cells and may help recruit NK cells to kill tumour cells [3,5,8].
Species: Human, Mouse, Rat
