Despite many studies on the genetic background of this disease, the pathogenesis remains unclear. The aim of the study is to comprehensively evaluate the polymorphism of the IL-10 promoter gene, its mRNA expression, and the serum IL-10 concentration of SLE female patients and females age-matched controls. Analyzing the association between the level of the tested cytokine and the polymorphism genotype-1082; -819; -592, we found statistically higher serum IL-10 levels in SLE patients compared to in healthy controls (11.9 \u00b1 2.2 pg\/mL vs. 9.4 \u00b1 1.7 pg\/mL, accordingly; p &lt; 0.0001). We did not find statistically significant differences in the gene polymorphism of IL-10 among SLE patients and controls. The most significant observation derived from our study is that IL-10 mRNA transcripts are upregulated in SLE patients compared to in healthy controls (p &lt; 0.0001). According to our results, the presence of the IL-10 genetic polymorphism has no clinical significance for the development of SLE, and subsequent differences in mRNA and IL-10 concentration results from the influence of other factors which should be the subject of further research.<\/jats:p>","DOI":"10.3390\/ijms25105511","type":"journal-article","created":{"date-parts":[[2024,5,20]],"date-time":"2024-05-20T08:20:31Z","timestamp":1716193231000},"page":"5511","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Impact of the IL-10 Gene Polymorphism on mRNA Expression and IL-10 Serum Concentration in Polish Lupus Patients"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7763-1770","authenticated-orcid":false,"given":"Agnieszka","family":"\u017bak-Go\u0142\u0105b","sequence":"first","affiliation":[{"name":"Department of Internal, Autoimmune and Metabolic Diseases, School of Medicine, Medical University of Silesia, 40-055 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3723-3591","authenticated-orcid":false,"given":"Pawe\u0142","family":"Cie\u015blik","sequence":"additional","affiliation":[{"name":"Department of Internal, Autoimmune and Metabolic Diseases, School of Medicine, Medical University of Silesia, 40-055 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Urszula","family":"Siekiera","sequence":"additional","affiliation":[{"name":"Regional Blood Donation and Treatment Center, 40-074 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dariusz","family":"Ku\u015bmierz","sequence":"additional","affiliation":[{"name":"Department of Cell Biology, School of Pharmacy, Medical University of Silesia, 41-200 Sosnowiec, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antoni","family":"Hrycek","sequence":"additional","affiliation":[{"name":"Department of Internal, Autoimmune and Metabolic Diseases, School of Medicine, Medical University of Silesia, 40-055 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3289-1050","authenticated-orcid":false,"given":"Micha\u0142","family":"Holecki","sequence":"additional","affiliation":[{"name":"Department of Internal, Autoimmune and Metabolic Diseases, School of Medicine, Medical University of Silesia, 40-055 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"755","DOI":"10.1111\/joim.13448","article-title":"The role of environmental exposures and gene-environment interactions in the etiology of systemic lupus erythematous","volume":"291","author":"Woo","year":"2022","journal-title":"J.
