Dr. Xing's research interests are gene expression and regulation of cytokines and chemokines, the regulation of inflammation, neuroimmunology, and the role of inflammation and growth factors, inflammatory cytokines and chemokines in wound healing. Dr. Xing's research focuses on defining the function changes of fibroblast cells and mechanisms that underlie the formation of incisional hernia. Investigation involves precisely recording cell proliferation, secretion of collagen by fibroblast form normal healing and hernia animal models. Intracellular signaling proteins: defining the signal pathway activated by strength load on the fibroblast.
