| Summary / Zusammenfassung | In accordance with previously published studies and our own preliminary results, we hypothesize the following: · Matrix metalloproteinases (MMP) are up-regulated during the earlier decisive stages of chronic rejection, prior to the occurrence of end-stage tissue sclerosis. Thereby, MMP act as pro-inflammatory mediators and actively participate in tissue damage associated with chronic allograft rejection. Possible mechanisms are direct tissue injury, augmentation of excess cell proliferation/migration (e.g. vascular smooth muscle cells and fibroblasts), and facilitation of tissue invasion by extrinsic inflammatory cells (e.g. lymphocytes). · MMP inhibition, for instance by the use of synthetic MMP inhibitors, ameliorates tissue damage during chronic allograft rejection. |
