Wnt Signaling in Inflammation in Tissue Repair and Regeneration.

Inflammation is the first response occurring after damage or infection, which is a defensive process for the body. It is well known that excessive inflammation can lead to further diseases such as fibrosis. But a regenerative inflammatory response can accelerate the process of repairing injury, in which a variety of cytokines, immune cells, and stem cells are involved. The Wnt signaling pathway was originally known in the field of development. Recently, its role in regenerative inflammation has gradually been established. Wnt signaling can regulate cell proliferation and differentiation through regulating participants of regenerative inflammation. Canonical and noncanonical Wnt signaling pathways are coordinated to maintain homeostasis. Based on the process of regenerative inflammation and recent research in this field, this paper reviews how the Wnt signaling pathway interact with other cells and pathways.
