The Inflammatory Response in the Context of Tissue Injury: Roles of Tyro3, Axl, and Mer (TAM) Receptors in Liver Ischemia/Reperfusion Injury
J. Zhang, M. Ni, D. Jin, H. Zhang, R. Busuttil, J. Kupiec-Weglinski, Y. Zhai
Dumont-UCLA Transplant Center, Los Angeles, CA
*Purpose: Although the inflammatory response in liver ischemia reperfusion injury has been studied extensively, how the context of tissue injury (presence of necrotic/apoptotic cells) regulates…
