Upon acute liver damage, BMP-9 expression is transiently down-regulated and blocking BMP-9 under conditions of chronic damage ameliorated liver fibrogenesis in C57BL/6 mice. Thereby, BMP-9 acted as a pro-fibrogenic cytokine in the liver but without directly activating isolated HSC in vitro. Lipopolysaccharide (LPS), an endotoxin derived from the membrane of Gram-negative bacteria in the gut, is known to be essential in the pathogenesis of diverse kinds of liver diseases. The aim of the present project was therefore to investigate how high levels of BMP-9 in the context of LPS signalling might result in enhanced liver damage. For this purpose, we stimulated human liver sinusoidal endothelial cells (LSEC) with LPS and incubated primary human liver myofibroblasts (MF) with the conditioned medium of these cells. We found that LPS led to the secretion of factors from LSEC that upregulate BMP-9 expression in MF. At least one of these BMP-9 enhancing factors was defined to be IL-6. High BMP-9 in turn, especially in combination with LPS stimulation, induced the expression of certain capillarization markers in LSEC and enhanced the LPS-mediated induction of pro-inflammatory cytokines in primary human macrophages. In LSEC, pre-treatment with BMP-9 reduced the LPS-mediated activation of the NfkB pathway, whereas in macrophages, LPS partially inhibited the BMP-9/Smad-1 signaling cascade. In vivo, in mice, BMP-9 led to the enhanced presence of F4/80-positive cells in the liver and it modulated the LPS-mediated regulation of inflammatory mediators. In summary, our data point to BMP-9 being a complex and highly dynamic modulator of hepatic responses to LPS: Initial effects of LPS on LSEC led to the upregulation of BMP-9 in MF but sustained high levels of BMP-9 in turn promote pro-inflammatory reactions of macrophages. Thereby, the spatial and timely fine-tuned presence (or absence) of BMP-9 is needed for efficient wound-healing responses in the liver. 000153912 536__ $$0G:(DE-HGF)POF3-321$$a321 - Basic Concepts (POF3-321)$$cPOF3-321$$fPOF III$$x0 000153912 588__ $$aDataset connected to CrossRef, PubMed, 000153912 7001_ $$aKarch, Julius$$b1 000153912 7001_ $$aGermann, Lena$$b2 000153912 7001_ $$aCai, Chen$$b3 000153912 7001_ $$aRausch, Vanessa$$b4 000153912 7001_ $$00000-0002-0338-3727$$aBirgin, Emrullah$$b5 000153912 7001_ $$aRahbari, Nuh$$b6 000153912 7001_ $$aSeitz, Tatjana$$b7 000153912 7001_ $$aHellerbrand, Claus$$b8 000153912 7001_ $$0P:(DE-He78)5ef958977fa3c0658679b496419ce762$$aKönig, Courtney$$b9 000153912 7001_ $$0P:(DE-He78)2e92d0ae281932fc7347d819fec36b0b$$aAugustin, Hellmut$$b10$$udkfz 000153912 7001_ $$aMogler, Carolin$$b11 000153912 7001_ $$00000-0001-8918-2266$$ade la Torre, Carolina$$b12 000153912 7001_ $$aGretz, Norbert$$b13 000153912 7001_ $$aItzel, Timo$$b14 000153912 7001_ $$aTeufel, Andreas$$b15 000153912 7001_ $$aEbert, Matthias P A$$b16 000153912 7001_ $$00000-0002-1814-4796$$aBreitkopf-Heinlein, Katja$$b17 000153912 773__ $$0PERI:(DE-600)2661518-6$$a10.3390/cells9030617$$gVol. 9, no. 3, p. 617 -$$n3$$pE617$$tCells$$v9$$x2073-4409$$y2020 000153912 909CO $$ooai:inrepo02.dkfz.de:153912$$pVDB 000153912 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)5ef958977fa3c0658679b496419ce762$$aDeutsches Krebsforschungszentrum$$b9$$kDKFZ 000153912 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)2e92d0ae281932fc7347d819fec36b0b$$aDeutsches Krebsforschungszentrum$$b10$$kDKFZ 000153912 9131_ $$0G:(DE-HGF)POF3-321$$1G:(DE-HGF)POF3-320$$2G:(DE-HGF)POF3-300$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lHerz-Kreislauf-Stoffwechselerkrankungen$$vBasic Concepts$$x0 000153912 9141_ $$y2020 000153912 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bCELLS-BASEL : 2017 000153912 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000153912 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000153912 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000153912 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central 000153912 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000153912 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000153912 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Blind peer review 000153912 915__ $$0LIC:(DE-HGF)CCBYNV$$2V:(DE-HGF)$$aCreative Commons Attribution CC BY (No Version)$$bDOAJ 000153912 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000153912 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000153912 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000153912 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000153912 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000153912 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000153912 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000153912 9201_ $$0I:(DE-He78)A190-20160331$$kA190$$lA190 Vaskuläre Onkologie und Metastatistierung$$x0 000153912 980__ $$ajournal 000153912 980__ $$aVDB 000153912 980__ $$aI:(DE-He78)A190-20160331 000153912 980__ $$aUNRESTRICTED
