Abstract:

Previous studies on granzyme B mainly focused on its role in inducing apoptosis of tumor cells or virus-infected cells. In recent years, more and more studies have found that granzyme B can also play a role in the extracellular matrix, leading to poor injury repair. Granzyme B promotes tissue inflammation by inducing the expression of inflammatory factors, destroying vascular integrity and increasing inflammatory cell infiltration, and promotes tissue fibrosis by releasing transforming growth factor-β (TGF-β), activating interleukin (IL)-18 and degrading decorin. The role of granzyme B in injury repair has attracted increasing attention. This article reviews the mechanism of granzyme B in promoting inflammation and fibrosis.

Key words: Granzymes, Inflammation, Fibrosis, Injury repair
