Induction of heat shock protein in cardiac allograft rejection--a cyclosporine-suppressible response

Transplantation
E A DavisR Udelsman

Abstract

The cellular response to a wide variety of stresses results in the synthesis of a family of proteins termed heat shock proteins (HSPs). To determine if acute allograft rejection could induce these proteins in a transplanted graft, we examined the HSP response to acute cardiac allograft rejection and analyzed the effect of immunosuppression upon this response. Donor hearts obtained from either Lewis (LEW) or ACI rats were heterotopically transplanted in recipient LEW rats. There were 4 experimental groups: untreated isografted (LEW to LEW) animals (n = 14), untreated allografted (ACI to LEW) animals (n = 14), cyclosporine-treated (10 mg/kg SQ/day) isografted animals (n = 12), and cyclosporine-treated allografted animals (n = 12). Animals were sacrificed on posttransplantation day 2, 4, or 6 (time of rejection for untreated allografts); n = 4-5 for each time point per group. At these times tissue obtained from the transplanted heart was examined histologically and analyzed for HSP72 by quantitative Northern and Western blots. The level of HSP72 in the untreated allografts progressively increased between 2, 4, and 6 days posttransplantation and was significantly greater than that of the untreated isografts at all time points.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
