Background: The aim of our work was to investigate the effects of
-3 polyunsaturated fatty acids on apoptosis and granzyme B, perforin,
and cation-independent mannose 6-phosphate/insulin-like growth factor receptor
(CI-MPR) expression of intestinal epithelial cells of chronic rejection after
small intestinal transplantation. Methods: Small bowel
transplantation was performed in a rat combination of 3 groups: group 1,
Lewis-to-Lewis; group 2, F344-to-Lewis, dietary corn oil; group 3,
F344-to-Lewis, dietary fish oil. All recipients were killed at 16 weeks
posttransplantation. The apoptosis rate of mucosal cells was evaluated by flow
cytometry. The expression of granzyme B, perforin, and CI-MPR was analyzed by
reverse transcriptase PCR. Results: A high apoptotic rate was
observed when the allografts demonstrated 1 or more histologic features of
chronic rejection. -3 Polyunsaturated fatty acids decreased in rate of
the apoptosis, and it can inhibit the expression of granzyme B, perforin, and
CI-MPR. Conclusions: -3 Polyunsaturated fatty acids can
suppress the rejection to mucosal cells of allograft at the time of chronic
rejection in small intestinal transplantation, which may be significant in
increasing the surviving rate of allograft, delaying the chronic dysfunction,
and prolonging the lifetime of both allograft and acceptor.
