Neuropeptide PACAP Protects Hepatocyte against Liver Ischemia/Reperfusion Injury by Promoting Yes-Associated Protein (YAP) Function
Z. Xue, Y. Liu, C. Zhang, R. Busuttil, J. Kupiec-Weglinski, H. Ji.
Dept of Surgery, The DumontUCLA Transplant Center, Los Angeles, CA.
Background: Previously we have demonstrated that neuropeptide pituitary adenylate cyclase-activating polypeptides (PACAP) suppressed local inflammation, and protected liver against IRI by innervating the liver and…
