Nanoparticles encapsulating rapamycin (ImmTOR) suppress adaptive immune responses and induce the hepatic tolerogenic immune response.<\/jats:p>\n AIM<\/jats:p>\n To investigate the effects of ImmTOR in PBC mouse models.<\/jats:p>\n METHODS<\/jats:p>\n PBC models were induced in C57BL\/6 mice by two immunizations of 2-octynoic acid-coupled bovine serum albumin at two-week intervals, and polycytidylic acid every three days. The PBC mouse models were separated into the treatment group and the control group. The levels of alkaline phosphatase (ALP) and alanine aminotransferase in the mice were detected using an automatic biochemical analyzer. Liver and spleen mononuclear cells were analyzed by flow cytometry, and serum anti-mitochondrial antibodies (AMA) and the related cytokines were analyzed by enzyme-linked immunosorbent assay. Liver histopathology was examined by hematoxylin and eosin staining and scored.<\/jats:p>\n RESULTS<\/jats:p>\n After treatment with ImmTOR, the ALP level was significantly decreased (189.60 U\/L \u00b1 27.25 U\/L vs 156.00 U\/L \u00b1 17.21 U\/L, P < 0.05), the level of AMA was reduced (1.28 ng\/mL \u00b1 0.27 ng\/mL vs 0.56 ng\/mL \u00b1 0.07 ng\/mL, P < 0.001) and the expression levels of interferon gamma and tumor necrosis factor \u03b1 were significantly decreased (48.29 pg\/mL \u00b1 10.84 pg\/mL vs 25.01 pg\/mL \u00b1 1.49 pg\/mL, P < 0.0001) and (84.24 pg\/mL \u00b1 23.47 pg\/mL vs 40.66 pg\/mL \u00b1 14.65 pg\/mL, P < 0.001). The CD4+ T lymphocytes, CD8+ T lymphocytes and B lymphocytes in the liver were significantly reduced, with statistically significant differences (24.21% \u00b1 6.55% vs 15.98% \u00b1 3.03%, P < 0.05; 9.09% \u00b1 1.91% vs 5.49% \u00b1 1.00%, P < 0.001; 80.51% \u00b1 2.96% vs 75.31% \u00b1 4.34%, P < 0.05). The expression of CD8+ T lymphocytes and B lymphocytes in the ImmTOR treatment group also decreased (9.09% \u00b1 1.91% vs 5.49% \u00b1 1.00%, P < 0.001; 80.51% \u00b1 2.96% vs 75.31% \u00b1 4.34%, P < 0.05). The liver pathology of PBC mice in the treatment group showed reduced inflammation and a decreased total pathology score, and the difference in the scores was statistically significant (4.50 \u00b1 2.88 vs 1.75 \u00b1 1.28, P < 0.05).<\/jats:p>\n CONCLUSION<\/jats:p>\n ImmTOR can improve biochemistry and pathology of liver obvious by inhibiting the expression of CD8+ T cells and B cells, and reducing the titer of AMA.<\/jats:p>","DOI":"10.4254\/wjh.v17.i6.104073","type":"journal-article","created":{"date-parts":[[2025,6,25]],"date-time":"2025-06-25T09:44:32Z","timestamp":1750844672000},"source":"Crossref","is-referenced-by-count":2,"title":["Effect of rapamycin nanoparticles in an animal model of primary biliary cholangitis"],"prefix":"10.4254","volume":"17","author":[{"given":"Yu-Shu","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xian-Rui","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhi-Min","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin-Long","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao-Lin","family":"Cui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan-Biao","family":"Song","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun-Ji","family":"Ma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hui-Fang","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-Xia","family":"Gao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao-Hui","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2060","published-online":{"date-parts":[[2025,6,27]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1111\/jgh.15329"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cld.2023.06.005"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1016\/j.hbpd.2022.10.004"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1002\/btm2.10068"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.1001597"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1002\/hep.28641"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1038\/s41423-022-00904-y"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1038\/ajg.2017.440"},{"key":"B9","unstructured":"Real-World Effectiveness of Obeticholic Acid in Patients With Primary Biliary Cholangitis.
