Macrophages are a crucial part of the immune system and have unique functions, such as polarization. Fibulin-3, an ECM protein, may play a vital role in this dynamic interplay. Fibulin-3 expression is elevated in periodontitis and is closely related to immune cell function. Inhibiting fibulin-3 can alleviate periodontitis by reducing infiltration of immune cells and M1 macrophage ratio. Furthermore, fibulin-3 promoted macrophage M1 polarization by activating the PI3K/AKT signaling pathway through EGFR binding. Our findings offer a clinically relevant rationale for immune response modulation through fibulin-3.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16716,"journal":{"name":"Journal of periodontology","volume":"96 5","pages":"440-454"},"PeriodicalIF":4.2,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142841624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the proapoptotic Bcl-2-associated X protein (Bax) and antiapoptotic B-cell lymphoma-extra large (Bcl-xl) levels and their association with interleukin-22 (IL-22) and transforming growth factor beta 1 (TGF-β1) in the gingival crevicular fluid (GCF) of patients with periodontitis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A total of 75 systemically healthy nonsmokers were enrolled, of whom 23 had stage III periodontitis, 26 had gingivitis, and 26 were periodontally healthy. Whole-mouth clinical periodontal measurements were recorded. Bax, Bcl-xl, IL-22, and TGF-β1 levels in the GCF were determined by enzyme-linked immunosorbent assay (ELISA).

The B-cell lymphoma 2-associated X protein (Bax) and B-cell lymphoma-extra large (Bcl-xl) are apoptosis-related proteins, which promote and inhibit cell death, respectively.

Therapy outcomes were associated with tooth-related factors, namely tooth type, tooth location (maxilla/mandible), number of roots, involvement of the root furcation area in multi-rooted teeth, pulp vitality, mobility, restoration, presence of plaque and bleeding upon periodontal probing, using mixed-effects models. The results revealed that repeated nonsurgical therapy was effective in reducing inflammation and clinical signs of disease, with moderate residual periodontal defects responding better than deep defects.
