This Mendelian randomization (MR) study aims to estimate the causal effects of diabetes-related traits on OLP and identify potential mediating factors.\n                    <jats:bold>Methods:<\/jats:bold>\n                    Utilizing summary statistics from genome-wide association studies predominantly of European ancestry, we conducted univariable and multivariable MR to estimate overall and independent effects of four diabetes-related traits (type 1 diabetes [T1D], type 2 diabetes [T2D], fasting glucose, fasting insulin) on OLP. Two-step MR was employed to identify and assess the mediation proportion of 91 inflammatory factors.\n                    <jats:bold>Results:<\/jats:bold>\n                    Genetic susceptibility to T1D was found to increase the risk of OLP (inverse-variance weighted OR: 1.10, 95% CI: 1.04\u20131.16,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = 0.002), with consistent findings across all MR methods. The relationship between T1D and OLP remained robust after adjusting for T2D, fasting insulin, and fasting glucose. Furthermore, IL-10 was identified as a partial mediator, accounting for 23.3% of the causal effect of T1D on OLP. No potential pleiotropy for significant estimates was detected (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &gt; 0.05). Univariable MR analyses showed no significant causal relationship between T2D, fasting glucose, fasting insulin, and OLP development.\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    IL-10 may partially mediate the association between T1D and OLP. These findings provide genetic evidence suggesting a potential link between T1D and OLP through pathways beyond glycemic regulation, but should be interpreted with caution given the limitations of the study.\n                  <\/jats:p>","DOI":"10.1177\/0265539x261416458","type":"journal-article","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T01:41:35Z","timestamp":1768268495000},"page":"503-513","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of type 1 diabetes on oral lichen planus mediated by IL-10"],"prefix":"10.1177","volume":"43","author":[{"given":"Xin","family":"Chen","sequence":"first","affiliation":[{"name":"Jiangyin People\u2019s Hospital Affiliated to Nantong University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qianyi","family":"Wang","sequence":"additional","affiliation":[{"name":"Jiangyin People\u2019s Hospital Affiliated to Nantong University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zheng","family":"Cheng","sequence":"additional","affiliation":[{"name":"Jiangyin People\u2019s Hospital Affiliated to Nantong University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhibai","family":"Zhao","sequence":"additional","affiliation":[{"name":"The Affiliated Stomatological Hospital of Nanjing Medical University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Zhang","sequence":"additional","affiliation":[{"name":"Jiangyin People\u2019s Hospital Affiliated to Nantong University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9056-6709","authenticated-orcid":false,"given":"Qianglin","family":"Jiang","sequence":"additional","affiliation":[{"name":"Jiangyin People\u2019s Hospital Affiliated to Nantong University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,1,12]]},"reference":[{"key":"e_1_3_7_2_1","doi-asserted-by":"publisher","DOI":"10.1590\/1678-775720150075"},{"key":"e_1_3_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.identj.2021.07.003"},{"key":"e_1_3_7_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dyv071"},{"key":"e_1_3_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/gepi.21965"},{"key":"e_1_3_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10654-017-0255-x"},{"key":"e_1_3_7_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41588-021-00852-9"},{"key":"e_1_3_7_8_1","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2024.1332317"},{"key":"e_1_3_7_9_1","first-page":"157","article-title":"Elevated IL-10 concentrations in serum and saliva from patients with oral Lichen planus","volume":"42","author":"Dan H","year":"2011","unstructured":"Dan H, Liu W, Wang J, et al.
