Popis: | Background. The precise mechanisms underlying the development of chronic allograft nephropathy (CAN) and the associated renal fibrosis remain uncertain. The protein-crosslinking enzyme, tissue transglutaminase (tTg), has recently been implicated in renal fibrosis. Methods. We investigated the involvement of tTg and its crosslink product, [epsilon]-([gamma]-glutamyl) lysine, in 23 human kidney allografts during the early posttransplantation period and related these to changes of CAN that developed in 8 of them. Sequential biopsies were investigated using immunohistochemical, immunofluorescence, and in situ enzyme activity techniques. Results. From implantation, tTg (+266%) and [epsilon]-([gamma]-glutamyl) lysine crosslink (+256.3%) staining increased significantly (P |
