体外研究 (In Vitro) | The peptide kinetensin isolated from pepsin-treated human plasma induces a dose-dependent release of histamine when exposed to rat peritoneal mast cells. The threshold concentration is around 1 μM, the ED50is 10 μM, and the optimal concentration of between 100 to 1000 μM released 80% of the total histamine. Kinetensin is 10 to 100 times less potent than neurotensin and equipotent with the opioid peptide dynorphin. The histamine release is clearly temperature-dependent, with no release occurring at 0 or 45 ℃ and with an optimum around 37 ℃. The histamine release is significantly reduced in the absence of extracellular calcium[2]. | ||||||||||||||||
体内研究 (In Vivo) | Kinetensin also induces a dose-dependent increase in vascular permeability when injected intradermally into rats[2]. | ||||||||||||||||
