Abstract

The aim of the present study was to investigate the mechanism by which gadolinium chloride (GdCl3) inhibits Kupffer cell (KC) activation and its ability to suppress acute rejection and induce tolerance following liver transplantation in rats. Rats were randomly divided into control, liver transplantation with GdCl3 pretreatment and liver transplantation with normal saline pretreatment groups. The survival rate, liver function, hepatic pathological histology, cytokine levels in the liver and bile, activity of nuclear factor κ‑light‑chain‑enhancer of activated B cells (NF‑κB) in KCs, and expression levels of membranous molecules on the KCs were observed. It was identified that the one‑month survival rate in the GdCl3 group was significantly higher compared with that in the saline group (P<0.05). The liver function in the GdCl3 group gradually recovered following transplantation surgery; however, it progressively deteriorated in the saline group. There were minor changes of hepatic pathological histology in the GdCl3 group, whereas changes typical of acute rejection occurred in the saline group. In the GdCl3 group, the levels of interferon γ and interleukin (IL)‑2 were significantly lower whereas the levels of IL‑10 were significantly higher compared with those in the control and saline groups (all P<0.01). The IL‑4 levels in the GdCl3 and control groups were similar. The activity of NF‑κB in the saline group was significantly higher compared with those in the control and GdCl3 groups (P<0.01). The expression levels of major histocompatibility complex‑II, cluster of differentiation (CD)80 and CD86 on the KC membranes in the GdCl3 group was significantly lower compared with those in the control group (P<0.05); however, these membranous proteins were highly expressed in the saline group. These data indicate that GdCl3 efficiently inhibits the immunological activity of KCs, suppresses acute rejection and induces tolerance following liver allograft transplantation in rats.
