Abstract

Abstract:

BACKGROUND: Nuclear factor-κB as an important nuclear transcription factor, is a converge point for various signal transduction pathways, and participate in the regulation of reactive substances gene expression such as the immune cell proliferation, differentiation and apoptosis. The nuclear factor-κB plays an important role in humoral and cellular immune.
OBJECTIVE: To investigate the relationship between the nuclear factor-κB p65 protein expression and acute rejection in transplanted liver tissue of rhesus monkey.
METHODS: The rhesus monkey recipients were randomly divided into two groups: acute rejection group and control group. The acute rejection group did not received anti-rejection treatment after liver transplantation, and the control group was given anti-rejection treatment during and after liver transplantation. The blood samples were collected at 6, 12, 24 and 72 hours after transplantation, and the automatic biochemical analyzer was used to detect the levels of alanine aminotransferase and total bilirubin. Hematoxylin-eosin staining of transplanted liver tissue was performed to observe the morphological structure and rejection. The degree of rejection was evaluated according to the Banff scoring system, and the expression of nuclear factor-κB p65 in the liver tissue was detected with Western blot.
RESULTS AND CONCLUSION: When the acute rejection occurred after liver transplantation, the liver function change was observed after liver histopathological examination, the expression of nuclear factor-κB p65 in the liver tissue was up-regulated, and the degree of acute rejection was increased. In the early stage of acute rejection, the liver function and pathology were changed slightly, while the expression of nuclear factor-κB p65 was significantly increased. The results indicate that the detection of nuclear factor-κB p65 in the transplanted liver tissue has great significance for the early diagnosis of acute rejection after liver transplantation, and the nuclear factor-κB may be the new target for controlling the acute rejection.
