We now show that DKO mice recapitulate many features of human autoimmune hepatitis (AIH), including periportal and interstitial inflammation and fibrosis and elevated ALT. Infiltrating cells include CD8+ tissue resident memory T cells, type I innate lymphoid cells, and inflammatory monocyte\/macrophage cells that replace the Kupffer cell pool. Importantly, TLR9 expression by bone marrow-derived cells is required for the the development of AIH. TLR9 is highly expressed by inflammatory myeloid cells but not long-lived Kupffer cells. Furthermore, the initial recruitment of TLR9 expressing monocytes and subsequent activation of lymphocytes requires IFN\u03b3 signaling. These findings highlight a critical role of feed forward loop between TLR9 expressing monocyte-lineage cells and IFNg producing lymphocytes in autoimmune hepatitis.\n                <\/jats:p>","DOI":"10.1101\/2024.07.10.602775","type":"posted-content","created":{"date-parts":[[2024,7,16]],"date-time":"2024-07-16T21:55:13Z","timestamp":1721166913000},"source":"Crossref","is-referenced-by-count":2,"title":["IFN\u03b3 initiates TLR9-dependent autoimmune hepatitis in DNase II deficient mice"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3862-6848","authenticated-orcid":false,"given":"Kaiyuan","family":"Hao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5855-1006","authenticated-orcid":false,"given":"Kevin MingJie","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa","family":"Strauss","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon","family":"Subramanian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2136-8130","authenticated-orcid":false,"given":"Ann","family":"Marshak-Rothstein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"54368","reference":[{"key":"2024071804001131000_2024.07.10.602775v1.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2016.05.034"},{"key":"2024071804001131000_2024.07.10.602775v1.2","doi-asserted-by":"publisher","DOI":"10.1038\/ng1845"},{"key":"2024071804001131000_2024.07.10.602775v1.3","doi-asserted-by":"publisher","DOI":"10.1038\/ng1842"},{"key":"2024071804001131000_2024.07.10.602775v1.4","doi-asserted-by":"publisher","DOI":"10.1038\/nri3850"},{"key":"2024071804001131000_2024.07.10.602775v1.5","doi-asserted-by":"publisher","DOI":"10.1084\/jem.20161596"},{"key":"2024071804001131000_2024.07.10.602775v1.6","doi-asserted-by":"publisher","DOI":"10.1038\/s41577-018-0029-z"},{"key":"2024071804001131000_2024.07.10.602775v1.7","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-017-01932-3"},{"key":"2024071804001131000_2024.07.10.602775v1.8","doi-asserted-by":"publisher","DOI":"10.1038\/nature05245"},{"key":"2024071804001131000_2024.07.10.602775v1.9","doi-asserted-by":"publisher","DOI":"10.1038\/ni1146"},{"key":"2024071804001131000_2024.07.10.602775v1.10","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1215006109"},{"key":"2024071804001131000_2024.07.10.602775v1.11","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.1402573"},{"key":"2024071804001131000_2024.07.10.602775v1.12","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0131702"},{"key":"2024071804001131000_2024.07.10.602775v1.13","doi-asserted-by":"crossref","unstructured":"Li T , Yum S , Li M , Chen X , Zuo X , Chen ZJ . 2022.
