ABSTRACT
Introduction: Cyclosporine A is an immunosuppressor used to prevent rejection of transplanted organs. About the 30% of the patients treated with this immunosuppressor develop gingival overgrowth. However, the precise cellular events that lead to the pathology are unknown. The aim of this study is to understand how cyclosporine A could be altering the expression and production of collagen I.
Material and methods: Fibroblast cultures derived from a biopsy of a patient treated with cyclosporine A were used to document both the expression, by RT-PCR, and the production, by immunocytochemistry, of collagen I.
Results: The amount of messenger RNA for collagen I was higher in gingival fibroblast of the gum of a patient treated with cyclosporine A than in gingival fibroblast of the control person. In concordance with this result, the amount of collagen expressed in gingival overgrowth fibroblast increased with respect to the control fibroblast.
Conclusion: cyclosporine A induced the overexpression and overproduction of collagen type I by gum fibroblast.
