Abstract:
Objective:To investigate the role of signal lymphocyte activating molecule family member 5 (SLAMF5) in liver transplantation rejection in SD rats.Methods:Forty-five male SD rats without special pathogens, weight 260-300 g, aged 10-12 weeks were included. Among them, forty male SD rats (20 donors and 20 recipients respectively) were established with reference to the " two cuff" method. 15 liver transplantation model rats were randomly divided into 1 week (LT-1W) group, 2 weeks (LT-2W) group and 3 weeks (LT-3W) group, with 5 rats in each group, and 5 normal rats were taken as the normal control group. The expressions of SLAMF5, CD4 and CD8 were detected by polymerase chain reaction (PCR), Western blot and immunohistochemistry. The correlations between SLAMF5 expression in the lymphocyte infiltration area and the rejection activity index was analyzed.Results:The levels of alanine aminotransferase, aspartate aminotransferase and total bilirubin were significantly higher in LT-1W group, LT-2W group and LT-3W group than those in the normal control group (all P<0.05). PCR results showed that the relative expression of SLAMF5 mRNA were (5.44±1.11), (4.69±1.12), (2.18±0.68) respectively, which were increased in LT-1W group, LT-2W group and LT-3W group than those in normal control group (1.01±0.23), and the differences were statistically significant (all P<0.05). Immunohistochemical staining showed that SLAMF5 and CD4, CD8 positive T cells were mainly distributed in the portal area, hepatic lobule area and around the proliferative bile duct, and there was a certain overlap. Correlation analysis showed that there was a positive correlation between the expression of SLAMF5 in the lymphocyte infiltration area and the rejection activity index ( r=0.519, P=0.048). Conclusion:The expression of SLAMF5 is increased after liver transplantation in SD rats, and there is a correlation between SLAMF5 expression and liver transplantation rejection in rats.
