Abstract
Purpose of the research: Ligneous gingivitis is a rare disease characterized by nodular gingival enlargement secondary to fibrin deposits induced by micro-injury in the gingiva, which disorder results from plasminogen (PLG) deficiency. Although none have investigated the association of wound healing factors with ligneous gingivitis. In this study, in addition to a histopathologic examination of ligneous gingivitis in a case of type I PLG deficiency, we further present data showing the effect of wound healing factors in association with fibrin in vitro to clarify the pathobiology of ligneous gingivitis in PLG-deficient patients. Principle results: Immunohistochemical analysis revealed that transforming growth factor (TGF)-β1, connective tissue growth factor/CCN2 (CCN2), and endothelin-1 (ET-1) had accumulated in the extracellular matrix around the epithelial and fibroblastic cells near the fibrin deposition. Consistent with these results, fibrin and TGF-β1 synergistically up-regulated CCN2 and ET-1 gene expression in human dermal fibroblasts. Major conclusions: Fibrin plays a vicious role in ligneous gingivitis pathobiology by up-regulating CCN2 and ET-1 expression through the TGF-β signaling pathway.
