In this model, liver injury depends on both TNFRs, i.e., the 55-kDa TNFR1 as well as the 75-kDa TNFR2. We show in this report that the hepatic TNFRs are not transcriptionally regulated, but are regulated by receptor shedding. TNF directly mediates hepatocellular death by activation of TNFR1 but also induces the expression of inflammatory proteins, such as cytokines and adhesion molecules. Here we provide evidence that resistance of TNFR1(-/-) and TNFR2(-/-) mice against Con A hepatitis is not due to an impaired production of the central mediators TNF and IFN-gamma. Con A injection results in a massive induction of ICAM-1, VCAM-1, and E-selectin in the liver. Lack of either one of both TNFRs did not change adhesion molecule expression in the livers of Con A-treated mice, presumably reflecting the fact that other endothelial cell-activating cytokines up-regulated adhesion molecule expression. However, treatment of TNFR1(-/-) and TNFR2(-/-) mice with murine rTNF revealed a predominant role for TNFR1 for the induction of hepatic adhesion molecule expression. Pretreatment with blocking Abs against E- and P-selectin or of ICAM(-/-) mice with anti-VCAM-1 Abs failed to prevent Con A hepatitis, although accumulation of the critical cell population, i.e., CD4(+) T cells was significantly inhibited. Hence, up-regulation of adhesion molecules during acute hepatitis unlikely contributes to organ injury but rather represents a defense mechanism.","lang":"eng"}],"publication":"Journal of Immunology","publication_status":"published","doi":"10.4049/jimmunol.166.2.1300","author":[{"last_name":"Wolf","full_name":"Wolf, Dominik","first_name":"Dominik"},{"last_name":"Hallmann","first_name":"Rupert","full_name":"Hallmann, Rupert"},{"full_name":"Sass, Gabriele","first_name":"Gabriele","last_name":"Sass"},{"last_name":"Sixt","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","full_name":"Sixt, Michael K","first_name":"Michael K","orcid":"0000-0002-6620-9179"},{"full_name":"Küsters, Sabine","first_name":"Sabine","last_name":"Küsters"},{"last_name":"Fregien","first_name":"Bastian","full_name":"Fregien, Bastian"},{"last_name":"Trautwein","full_name":"Trautwein, Christian","first_name":"Christian"},{"full_name":"Tiegs, Gisa","first_name":"Gisa","last_name":"Tiegs"}],"_id":"3927","date_created":"2018-12-11T12:05:56Z","month":"01","citation":{"short":"D.
