Methods: This study investigated the impact of excessive dietary inorganic phosphate on intestinal and immune homeostasis in mice using gradient Pi exposure combined with an inflammatory model. Results: Pi overload induced atrophy in the thymus, spleen, and kidney; damaged the intestinal barrier; reduced the villus height-to-crypt-depth ratio; and decreased goblet cell numbers. Altered levels of serum sIgA and IgE, as well as intestinal IgA, IgG, IgE, and IgM, together with decreased IFN-\u03b1, indicated altered levels of immunoglobulins and cytokines under Pi treatment. Proteomic analysis revealed differential expression of key proteins, including CNTFR and Bcl2l1 in the JAK\/STAT pathway and metabolic regulators CPT1\u03b1 and IDH1, when comparing Pi-treated mice with the control group. Conclusions: These preliminary findings suggest that Pi may affect intestinal mucosal barrier function and systemic immune response through immune regulation and mitochondrial metabolic pathways, providing preliminary insight into the potential health implications of Pi overconsumption in humans.<\/jats:p>","DOI":"10.3390\/nu18101590","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T08:56:27Z","timestamp":1779094587000},"page":"1590","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Effects of High-Inorganic-Phosphorus Diet on Intestinal Mucosal Injury and Immune Alteration in Mice"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3773-6391","authenticated-orcid":false,"given":"Zongchao","family":"Sun","sequence":"first","affiliation":[{"name":"School of Life Sciences and Health, University of Health and Rehabilitation Sciences, Qingdao 266113, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-0107-3191","authenticated-orcid":false,"given":"Shiya","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Life Sciences and Health, University of Health and Rehabilitation Sciences, Qingdao 266113, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuxin","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Food Science and Engineering, Foshan University, Foshan 528225, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunhan","family":"Luan","sequence":"additional","affiliation":[{"name":"School of Life Sciences and Health, University of Health and Rehabilitation Sciences, Qingdao 266113, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinuo","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Life Sciences and Health, University of Health and Rehabilitation Sciences, Qingdao 266113, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Runzhe","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Life Sciences and Health, University of Health and Rehabilitation Sciences, Qingdao 266113, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiwei","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Food Science and Engineering, Foshan University, Foshan 528225, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danli","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Food Science and Engineering, Foshan University, Foshan 528225, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiankang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Life Sciences and Health, University of Health and Rehabilitation Sciences, Qingdao 266113, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-6952-8334","authenticated-orcid":false,"given":"Yinghui","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Life Sciences and Health, University of Health and Rehabilitation Sciences, Qingdao 266113, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1016\/bs.afnr.2021.02.001","article-title":"The emerging role of phosphorus in human health","volume":"96","author":"Bird","year":"2021","journal-title":"Adv.
