| 1 | Interleukin-33 drives hepatic fibrosis through activation of hepatic stellate cells显示文摘Liver fibrosis is a consequence of chronic liver disease,causing morbidity and mortality.Interleukin-33(IL-33)is a critical mediator of inflammation,which may be involved in the development of liver fibrosis.Here,we investigated the role of IL-33 in human patients and experimental bile-duct ligation(BDL)-induced fibrosis in mice.We report increased hepatic IL-33 expression in the murine BDL model of fibrosis and in surgical samples obtained from patients with liver fibrosis.Liver injury,inflammatory cell infiltration and fibrosis were reduced in the absence of the IL-33/ST2 receptor,and the activation of hepatic stellate cells(HSCs)was decreased in ST2-deficient mice.Recombinant IL-33 activated HSCs isolated from C57BL/6 mice,leading to the expression of IL-6,TGF-β,α-SMA and collagen,which was abrogated in the absence of ST2 or by pharmacological inhibition of MAPK signaling.Finally,administration of recombinant IL-33 significantly increased hepatic inflammation in sham-operated BL6 mice but did not enhance BDL-induced hepatic inflammation and fibrosis.In conclusion,BDL-induced liver inflammation and fibrosis are dependent on ST2 signaling in HSCs,and therefore,the IL-33/ST2 pathway may be a potential therapeutic target in human patients with chronic hepatitis and liver fibrosis. | Zhongming Tan Qianghui Liu Runqiu Jiang Long Lv Siamak S Shoto Isabelle Maillet Valerie Quesniaux Junwei Tang Wenjie Zhang Beicheng Sun Bernhard Ryffel | 2018 | Cellular & Molecular Immunology2018,15,4: | 24 |

| 4 | Interplay between nitric oxide and VIP in CCK-8-induced phasic contractile activity in the rabbit sphincter of Oddi显示文摘AIM: The sphincter of Oddi (SO) plays an important role in delivery of bile into the duodenum. To establish whether vasoactive intestinal polypeptide (VIP) and nitric oxide (NO) were involved in phasic contractile activity of the rabbit SO stimulated by cholecystokinin-octapeptide (CCK-8).METHODS: Isolated SO muscle rings were cleaned of fat and mounted horizontally on two small L-shaped hooksone of which was connected to a force transducer for the measurement of isometric tension. The experiments were carried out in a thermostatically controlled (37±0.2℃)organ bath (5 mL) containing Krebs solution. The organ fluid was gassed with 95% O2 and 50 mL/L CO2 to keep the pH at 7.40±0.05. Contractile responses to CCK-8 (1μmol/L) were evaluated in the presence and absence of N^G-nitro-L-arginine (LNNA), an inhibitor of NO synthase (100μmol/L), and (p-chloro-D-Phe^6-Leu^17)-VIP (VIPa,30μmol/L), a VIP receptor antagonist.RESULTS: CCK-8 stimulated the phasic activity of the SO.NO synthase inhibition increased the frequency and amplitude of contractions with a slight increase in developed tension.Pre-incubation with VIPa also attenuated this CCK-8 effect.The combined application of LNNA and VIPa abolished the phasic activity of the muscle rings with a marked increase in tension in response to CCK-8.CONCLUSION: VIP and NO together contribute to an increase in phasic activity of SO. | Attila Pálv(o|¨)lgyi Réka Sári József Németh Annamária Szabolcs István Nagy Péter Hegyi János Lonovics Zoltán Szilvássy | 2005 | World Journal of Gastroenterology2005,11,21: | 11 |
| 5 | Functional distinction of rat liver natural killer cells from spleen natural killer cells under normal and acidic conditions in vitro显示文摘BACKGROUND: The microenvironment within solid tumors has often been shown to exhibit an acidic extracellular pH. Although the morphologic and functional differences in natural killer (NK) cells of the liver and spleen have been reported previously under physiological conditions, the difference under acidic conditions is still unclear. This study was to investigate the differences in the morphological and functional characteristics between rat liver and spleen NK cells under normal and acidic conditions in vitro. METHODS: Liver and spleen NK cells were isolated and purified from Sprague-Dawley rats by density gradient centrifugation and the Dynabeads FlowComp TM Flexi system, and stimulated for 4 days with or without IL-2 or treated with low pH or control for different times. Morphology was examined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), cell death and proliferation assays were performed by flow cytometry, IFN-γ production was tested by ELISA, and cytotoxic activity was evaluated by lactate dehydrogenase (LDH) release assay. RESULTS: Liver NK cells had significantly higher levels of cytotoxic activity than spleen NK cells under normal and acidic conditions, and the maximum difference was observed at pH 5.6. Further analysis revealed that the cytotoxic activity of NK cells was correlated with morphology, cell death, proliferative activity and IFN-γ production. By TEM, liver NK cells contained a greater number of electron-dense granules per cell at pH 5.6.Moreover, a modest elevation of cell death and reduction of proliferation of liver NK cells occurred within a range of 5.6-7.2. Interestingly, an acidic extracellular pH only marginally, and not significantly, suppressed IFN-γ production by liver NK cells. CONCLUSION: The sharp morphological and functional differences shown by the two types of NK cells in vitro indicate that liver NK cells are unexpectedly resistant to pH shock. | Li-Hong Lv, Jian-Dong Yu, Guo-Lin Li, Tian-Zhu Long, Wei Zhang, Ya-Jin Chen, Jun Min and Yun-Le Wan Department of Hepatobiliary Surgery, Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University Department of Breast Surgery, Guangzhou Women and Children’s Medical Center Guangzhou 510120, China Department of Hepatobiliary and Pancreatic Surgery, First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China | 2012 | Hepatobiliary & Pancreatic Diseases International2012,11,3: | 5 |
| 6 | Donor liver natural killer cells alleviate liver allograft acute rejection in rats显示文摘BACKGROUND:Liver enriched natural killer (NK) cells are of high immune activity.However,the function of donor liver NK cells in allogeneic liver transplantation (LTx) remains unclear.METHODS:Ten Gy of whole body gamma-irradiation (WBI) from a 60 Co source at 0.6 Gy/min was used for depleting donorderived leukocytes,and transfusion of purified liver NK cells isolated from the same type rat as donor (donor type liver NK cells,dtl NKs) through portal vein was performed immediately after grafting the irradiated liver.Post-transplant survival observation on recipients and histopathological detection of liver grafts were adoptive to evaluate the biological impact of donor liver NK cells on recipients' survival in rat LTx.RESULTS:Transfusion of dtl NKs did not shorten the survival time among the recipients of spontaneous tolerance model (BN to LEW rat) after rat LTx,but prolonged the liver graft survival among the recipients depleted of donor-derived leukocytes in the acute rejection model (LEW to BN rat).Compared to the recipients in the groups which received the graft depleted of donor-derived leukocytes,better survival and less damage in the allografts were also found among the recipients in the two different strain combinations of liver allograft due to transfusion of dtl NKs.CONCLUSIONS:Donor liver NK cells alone do not exacerbate liver allograft acute rejection.Conversely,they can alleviate it,and improve the recipients' survival. | Jian-Dong Yu,Tian-Zhu Long,Guo-Lin Li,Li-Hong Lv,Hao-Ming Lin,Yong-Heng Huang,Ya-Jin Chen and Yun-Le Wan Department of Hepatobiliary Surgery,Sun Yat-Sen Memorial Hospital,Sun Yat-Sen University,Guangzhou 510120,China Department of Breast Surgery,Guangzhou Women and Children’s Medical Center,Guangzhou 510120,China | 2011 | Hepatobiliary & Pancreatic Diseases International2011,10,4: | 2 |
