Abstract
Recently, thymic stromal lymphopoietin (TSLP), which is well studied in allergic diseases, has been reported in fibrotic diseases, including idiopathic pulmonary fibrosis and atopic dermatitis fibrosis. However, the role of TSLP in keloid is obscure. In this study, we assessed the expression of TSLP in keloid tissue and investigated the possible role of TSLP in keloid pathogenesis. We observed that TSLP expression was increased in keloid tissue compared to normal tissue. Furthermore, TSLP treatment induced increased collagen I and collagen III expression in fibroblasts via transforming growth factor-?; however, there was higher expression in keloid fibroblasts compared to normal fibroblasts. Stromal cell-derived factor-1?, which was recently reported to enhance wound healing through recruiting bone marrow-derived mesenchymal stem cells to the wound area, increased after TSLP treatment in fibroblasts and was primarily expressed in ?-smooth muscle action-positive myofibroblasts in keloid tissue. Furthermore, fibrocytes expressing CXCR4, a stromal cell-derived factor-1? receptor, were significantly increased in keloid tissue compared to normal tissue. Finally, intradermal TSLP injection on BALB/c mice increased stromal cell-derived factor-1? expression and CXCR4(+) fibrocytes infiltration. Our data suggest that TSLP is a potent inducer of collagen and transforming growth factor-? production in keloid fibroblasts. In addition, it might activate the CXCR4/stromal cell-derived factor-1 axis to increase fibrocyte infiltration into the keloid tissue.
