Prorepair extravascular fibrin(ogen) deposits are potentially subject to cross-linking by FXIII and other transglutaminases not typically resident in plasma. However, the impact of these alternative modifiers on fibrin(ogen) structure and function is not known. We tested the hypothesis that tissue transglutaminase (TG2) modifies FXIII-directed fibrin(ogen) cross-linking in vitro and within injured tissue. Global proteomic analysis after experimental acetaminophen (APAP)-induced acute liver injury revealed that intrahepatic fibrin(ogen) deposition was associated with hepatic TG2 levels that exceeded that of FXIII. Mass spectrometry-based cross-link mapping of in vitro fibrin matrices uncovered, to our knowledge, the first evidence of synergistic fibrin(ogen) \u03b1-\u03b1 cross-linking catalyzed by both transglutaminases. Fibrin(ogen) cross-linking was increased in livers from patients with APAP-induced acute liver failure. APAP-challenged TG2\u2212\/\u2212 mice displayed an altered pattern of FXIII-dependent fibrin(ogen)-\u03b3 and fibrin(ogen)-\u03b1 chain cross-linking aligned with the impact of TG2 on fibrin cross-linking in vitro. This shift in fibrin(ogen) cross-linking exacerbated pathologies including hepatic necrosis and sinusoidal congestion. The results, to our knowledge, are the first to indicate that TG2 impacts FXIII-directed fibrin(ogen) cross-linking, both in vitro and in vivo. The results suggest that TG2 functions to dynamically alter the structure of extravascular fibrin(ogen) to mitigate liver damage, a novel mechanism likely applicable across types of tissue injury.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1182\/blood.2024026938","type":"journal-article","created":{"date-parts":[[2025,2,26]],"date-time":"2025-02-26T11:56:13Z","timestamp":1740570973000},"page":"2507-2517","update-policy":"https:\/\/doi.org\/10.1182\/blood.2019cm0000","source":"Crossref","is-referenced-by-count":9,"title":["Integrated cross-linking by TG2 and FXIII generates hepatoprotective fibrin(ogen) deposits in injured liver"],"prefix":"10.1182","volume":"145","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2944-3118","authenticated-orcid":false,"given":"Zimu","family":"Wei","sequence":"first","affiliation":[{"name":"1Department of Pathobiology and Diagnostic Investigation, Michigan State University, East Lansing, MI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5561-1917","authenticated-orcid":false,"given":"Nana Kwame Kwabi","family":"Boateng","sequence":"additional","affiliation":[{"name":"1Department of Pathobiology and Diagnostic Investigation, Michigan State University, East Lansing, MI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren R.","family":"Schmitt","sequence":"additional","affiliation":[{"name":"2Department of Biochemistry and Molecular Genetics, University of Colorado School of Medicine, Aurora, CO"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9023-098X","authenticated-orcid":false,"given":"Holly","family":"Cline","sequence":"additional","affiliation":[{"name":"1Department of Pathobiology and Diagnostic Investigation, Michigan State University, East Lansing, MI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Theodora","family":"Fernandes Fonseca","sequence":"additional","affiliation":[{"name":"1Department of Pathobiology and Diagnostic Investigation, Michigan State University, East Lansing, MI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ariana","family":"Newberry","sequence":"additional","affiliation":[{"name":"1Department of Pathobiology and Diagnostic Investigation, Michigan State University, East Lansing, MI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alicia","family":"Taylor","sequence":"additional","affiliation":[{"name":"1Department of Pathobiology and Diagnostic Investigation, Michigan State University, East Lansing, MI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jelle","family":"Adelmeijer","sequence":"additional","affiliation":[{"name":"3Surgical Research Laboratory and Section of Hepatobiliary Surgery and Liver Transplantation, Department of Surgery, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren G.","family":"Poole","sequence":"additional","affiliation":[{"name":"1Department of Pathobiology and Diagnostic Investigation, Michigan State University, East Lansing, MI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9901-854X","authenticated-orcid":false,"given":"R.
