1Role of HSP-90 for increased nNOS-mediated vasodilation in mesenteric arteries in portal hypertension显示文摘AIM:To explore the role of heat shock protein-90 (HSP-90) for nitrergic vasorelaxation in the splanchnic circulation in rats with and without portal hypertension. METHODS: Neuronal nitric oxide synthase (nNOS) and HSP-90 were analyzed by immunofluorescence, western blotting and co-immunoprecipitation in the mesenteric vasculature and isolated nerves of portal-vein-ligated (PVL) rats and sham operated rats. In vitro perfused de-endothelialized mesenteric arterial vasculature was preconstricted with norepinephrine (EC80) and tested for nNOS-mediated vasorelaxation by periarterial nerve stimulation (PNS, 2-12 Hz, 45V) before and after incubation with geldanamycin (specific inhibitor of HSP-90 signalling, 3 μg/mL) or L-NAME (non-specific NOSblocker, 10-4 mol/L). RESULTS: nNOS and HSP-90 expression was significantly increased in mesenteric nerves from PVL as compared to sham rats. Moreover, nNOS and HSP-90 were visualized in mesenteric nerves by immunofluorescence and immunoprecipitation of nNOS co-immunoprecitated HSP-90 in sham and PVL rats. PNS induced a frequencydependent vasorelaxation which was more pronounced in PVL as compared to sham rats. L-NAME and geldanamycin markedly reduced nNOS-mediated vasorelaxation abrogating differences between the study groups. The effect of L-NAME and geldanamycin on nNOS-mediated vasorelaxation was significantly greater in PVL than in sham animals. However, no difference in magnitude of effect between L-NAME and geldanamycin was noted. CONCLUSION: HSP-90 acts as a signalling mediator of nNOS-dependent nerve mediated vascular responses in mesenteric arteries, and the increased nitrergic vasorelaxation observed in portal hypertension is mediated largely by HSP-90.Lukas Moleda Lars Jurzik Matthias Froh Erwin Gbele Claus Hellerbrand Rainer H Straub Jürgen Schlmerich Reiner Wiest 2010World Journal of Gastroenterology2010,16,15:4
2Distribution and effects of polymorphic RANTES gene alleles in HIV/HCV coinfection - A prospective cross-sectional study显示文摘AIM: Chemokines and their receptors are crucial for immune responses in HCV and HIV infection. RANTES gene polymorphisms lead to altered gene expression and influence the natural course of HIV infection. Therefore,these mutations may also affect the course of HIV/HCV coinfection.METHODS: We determined allele frequencies of RANTES-403 (G→A), RANTES-28 (C→G) and RANTESIN1.1 (T→C) polymorphisms using real-time PCR and hybridization probes in patients with HIV (n = 85), HCV (n= 112), HIV/HCV coinfection (n = 121), and 109 healthy controls. Furthermore, HIV and HCV loads as well as CD4+ and CD8+ cell counts were compared between different RANTES genotypes.RESULTS: Frequencies of RANTES-403 A, RANTES-28 G and RANTES-IN1.1 C alleles were higher in HIV infected patients than in healthy controls (-403: 28.2% vs 15.1%,P = 0.002; -28: 5.4% vs 2.8%, not significant; IN1.1:19.0% vs 11.0%, P = 0.038). In HIV/HCV coinfected patients, these RANTES alleles were less frequent than in patients with HIV infection alone (15.4% P = 0.002;1.7%; P = 0.048; 12.0%; not significant). Frequencies of these alleles were not significantly different between HIV/HCV positive patients, HCV positive patients and healthy controls.CONCLUSION: All three RANTES polymorphisms showed increased frequencies of the variant allele exclusively in patients with HIV monoinfection. The finding that the frequencies of these alleles remained unaltered in HIV/HCV coinfected patients suggests that HCV coinfection interferes with selection processes associated with these alleles in HIV infection.Golo Ahlenstiel Agathe Iwan Jacob Nattermann Karin Bueren Jürgen K Rockstroh Hans H Brackmann Bernd Kupfer Olfert Landt Amnon Peled Tilman Sauerbruch Ulrich Spengler Rainer P Woitas 2005World Journal of Gastroenterology2005,11,48:3

5Chronic hepatitis C:Treat or wait? Medical decision making in clinical practice显示文摘AIM:To analyzes the decision whether patients with chronic hepatitis C virus (HCV) infection are treated or not.METHODS:This prospective cohort study included 7658 untreated patients and 6341 patients receiving pegylated interferon α2 a/ribavirin,involving 434 physicians/institutions throughout Germany (377 in private practice and 57 in hospital settings).A structured questionnaire had to be answered prior to the treatment decision,which included demographic data,information about the personal life situation of the patients,anamnesis and symptomatology of hepatitis C,virological data,laboratory data and data on concomitant diseases.A second part of the study analyzes patients treated with pegylated interferon α2a.All questionnaires included reasons against treatment mentioned by the physician.RESULTS:Overall treatment uptake was 45%.By multivariate analysis,genotype 1/4/5/6,HCV-RNA ≤ 520 000 IU/mL,normal alanine aminotransferase (ALT),platelets ≤ 142 500/μL,age > 56 years,female gender,infection length > 12.5 years,concomitant diseases,human immunodeficiency virus co-infection,liver biopsy not performed,care in private practice,asymptomatic disease,and unemployment were factors associated with reduced treatment rate.Treatment and sustained viral response rates in migrants (1/3 of cohort) were higher than in German natives although 1/3 of migrants had language problems.Treatment rate and liver biopsy were higher in clinical settings when compared to private practice and were low when ALT and HCV-RNA were low.CONCLUSION:Some reasons against treatment were medically based whereas others were related to fears,socio-economical problems,and information deficits both on the side of physicians and patients.Claus Niederau Dietrich Hüppe Elmar Zehnter Bernd Mller Renate Heyne Stefan Christensen Rainer Pfaff Arno Theilmeier Ulrich Alshuth Stefan Mauss 2012World Journal of Gastroenterology2012,18,12:2

17Stimulation of TNF receptor type 2 expands regulatory T cells and ameliorates established collagen-induced arthritis in mice显示文摘Tumor necrosis factor(TNF)and its receptors TNF receptor type 1(TNFR1)and type 2(TNFR2)have a central role in chronic inflammatory diseases.While TNFR1 mainly confers inflammation,activation of TNFR2 elicits not only pro-inflammatory but also anti-inflammatory effects.In this study,we wanted to investigate the anti-inflammatory therapeutic potential of selective activation of TNFR2 in mice with established collageninduced arthritis.Mice with established arthritis induced by immunization with bovine collagen type II were treated with six injections of the TNFR2-specific agonist TNCscTNF80,given every second day.Two days after treatment cessation,the cell compositions of bone marrow,spleen and lymph nodes were analyzed.Mice were visually scored until day 30 after the start of therapy and the degree of joint inflammation was determined by histology.Treatment with TNCscTNF80 increased arthritis-induced myelopoiesis.Little effect was seen on the infiltration rate of inflammatory immature myeloid cells and on the reduction of lymphoid cells in secondary lymphoid organs.Upon treatment,frequency of regulatory T(Treg)cells in the CD4+T-cell population was increased in both spleen and inguinal lymph nodes.In addition,the expression of TNFR2 on Treg cells was enhanced.The clinical score started to improve 1 week after cessation treatment and remained lower 30 days after initiation of therapy.The histological score also revealed amelioration of joint inflammation in TNCscTNF80-treated versus control mice.Activation of TNFR2 might provide a suitable therapeutic strategy in autoimmune arthritis by increasing the numbers of regulatory cell types,in particular Treg cells,and by attenuation of arthritis.Vanessa Lamontain Tobias Schmid Dorothea Weber-Steffens David Zeller Zsuzsa Jenei-Lanzl Harald Wajant Rainer H Straub Daniela N Männel 2019Cellular & Molecular Immunology2019,16,1:1
