PG - 311-6 AB - Cicatricial pemphigoid (CP) is an autoimmune mucocutaneous blistering disease associated with scarring. Heat shock protein 47 (HSP47) is thought to play an important role in fibrogenesis, but its role in skin lesions of cicatricial pemphigoid is not yet known. In the present study, we examined the role of HSP47 in dermal fibrosis in cutaneous lesions of a CP patient. Skin biopsies from a patient with CP, and from normal subjects were studied for the expression of HSP47, and interstitial collagens (type I and type III collagens) by immunohistochemistry. Dermal fibroblasts isolated from skin of normal individuals and from fibrotic skin of a CP patient were used to study the expression of HSP47, transforming growth factor beta 1 (TGF-beta 1), type I and type III collagens. Compared to the control skin sections, an increased expression of HSP47 was associated with an increased deposition of interstitial collagens in the fibrotic skin section of the CP patient. Similarly, in contrast to control dermal fibroblasts, the fibroblasts isolated and cultured from fibrotic skin of the CP patient, and grown in vitro, exhibited increased expression of HSP47, type I and type III collagens. Furthermore, compared to the normal control fibroblasts, an increased expression of TGF-beta 1 was detected in the dermal fibroblasts isolated from fibrotic skin of the CP patient. When dermal fibroblasts were treated with various concentrations of TGF-beta 1 (6.25, 12.5, 25, 50 and 100 ng/ml for 24 h), it induced the expression of both type I collagen and HSP47, as determined by quantitative real-time PCR. In conclusion, the expression of TGF-beta 1, HSP47, type I collagen and type III collagen was up-regulated in the fibrotic skin of CP patient, and a complex interaction of these molecules may initiate and propagate the fibrotic cascade in the skin of CP patients.
