However, major advances have been made over the past decade. The innate immune system is now recognized as playing a key role in the early stages of the disease, particularly through activation of interferon (IFN) pathways, driven in part by epithelial cells, which actively attract autoreactive lymphocytes. Furthermore, the mechanisms of B-cell activation in SjD are now better understood, notably with the recognition of BAFF (B-cell activating factor), a Tumor necrosis factor (TNF) family cytokine, whose production is highly dependent on type I and II IFN signaling. The involvement of other cell types, such as fibroblasts and T cells, has also been underlined. Significant progress has been achieved in elucidating lymphomagenesis, the most severe complication of SjD. Together, these advances provide a clearer picture of SjD pathogenesis and open avenues for the development of new targeted therapeutic strategies.<\/jats:p>","DOI":"10.3390\/jcm15051945","type":"journal-article","created":{"date-parts":[[2026,3,4]],"date-time":"2026-03-04T13:11:36Z","timestamp":1772629896000},"page":"1945","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Update on the Aetiopathogenesis of Sj\u00f6gren Disease: From Interferon Signaling to Epithelial Dysfunction"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6322-8801","authenticated-orcid":false,"given":"Lo\u00efc","family":"Meudec","sequence":"first","affiliation":[{"name":"Immuno-Rheumatology Department, H\u00f4pital Bic\u00eatre, Assistance Publique H\u00f4pitaux de Paris (AP-HP), Universit\u00e9 Paris-Saclay, 78 rue du G\u00e9n\u00e9ral Leclerc, 94275 Le Kremlin Bic\u00eatre, France"},{"name":"Center for Immunology of Viral Infections and Autoimmune Diseases, Institut Nationale de la Sant\u00e9 et de la Rercherche Medicale (INSERM), UMR 1184, IDMIT, Universit\u00e9 Paris Saclay, 78 rue du G\u00e9n\u00e9ral Leclerc, 94275 Le Kremlin Bic\u00eatre, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6809-0733","authenticated-orcid":false,"given":"Gaetane","family":"Nocturne","sequence":"additional","affiliation":[{"name":"Immuno-Rheumatology Department, H\u00f4pital Bic\u00eatre, Assistance Publique H\u00f4pitaux de Paris (AP-HP), Universit\u00e9 Paris-Saclay, 78 rue du G\u00e9n\u00e9ral Leclerc, 94275 Le Kremlin Bic\u00eatre, France"},{"name":"Center for Immunology of Viral Infections and Autoimmune Diseases, Institut Nationale de la Sant\u00e9 et de la Rercherche Medicale (INSERM), UMR 1184, IDMIT, Universit\u00e9 Paris Saclay, 78 rue du G\u00e9n\u00e9ral Leclerc, 94275 Le Kremlin Bic\u00eatre, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4244-5417","authenticated-orcid":false,"given":"Xavier","family":"Mariette","sequence":"additional","affiliation":[{"name":"Immuno-Rheumatology Department, H\u00f4pital Bic\u00eatre, Assistance Publique H\u00f4pitaux de Paris (AP-HP), Universit\u00e9 Paris-Saclay, 78 rue du G\u00e9n\u00e9ral Leclerc, 94275 Le Kremlin Bic\u00eatre, France"},{"name":"Center for Immunology of Viral Infections and Autoimmune Diseases, Institut Nationale de la Sant\u00e9 et de la Rercherche Medicale (INSERM), UMR 1184, IDMIT, Universit\u00e9 Paris Saclay, 78 rue du G\u00e9n\u00e9ral Leclerc, 94275 Le Kremlin Bic\u00eatre, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"931","DOI":"10.1056\/NEJMcp1702514","article-title":"Primary Sj\u00f6gren\u2019s Syndrome","volume":"378","author":"Mariette","year":"2018","journal-title":"N.
