“…8,9 Interleukins (ILs) are cytokines that play an important role in the activation, differentiation, proliferation, maturation and migration of immune cells. 10 Studies have shown that IL-13 contributes to the pathogenesis of fibroproliferative diseases, such as pulmonary fibrosis, liver cirrhosis, myocardial fibrosis, progressive kidney disease and pathological skin scarring, among others. [11][12][13][14] Furthermore, IL-13 was associated with elevated production of total collagens in normal human skin and keloid fibroblasts (FBs), whereas FBs in various scarring diseases produced more fibrin, suggesting that IL-13 is associated with fibrosis.…”
