OBJECTIVE To understand the roles of innate lymphoid cells in the pathophysiology of colorectal cancer (CRC) in the mouse model. METHODS CRC was induced using azoxymethane (AOM) and dextran sulfate sodium (DSS) in Balb/c mice (the chemically induced group=18 mice), or orthotopic injection of CT-26 cell line into the colon of another set of Balb/c mice (the orthotopic group=14mice). Normal saline was injected into 18 mice, as the sham group. After 80 days, the chemically induced group was divided into two subgroups, dysplasia (8 mice) and reparative change (10 mice), based on pathological examinations. The frequencies of ILC1, 2, and 3 were then measured in colon tissues using flow cytometry by four markers including an anti-mouse lineage cocktail (FITC anti-mCD3/FITC anti-mGr-1/FITC anti-mCD11b/ FITC anti-mCD45R (B220)/FITC anti-mTer-119), PE/Cy7 anti-mouse CD45, PE anti-mouse CD117 (c-kit), and APC anti-mouse IL-33 Rα (ST2). RESULTS The total ILC population was significantly higher in the chemically induced reparative change compared with the sham group. ILC1 percentage in the chemically induced reparative change was significantly higher compared to those in the other three groups (Sham, chemically induced dysplasia and orthotopic dysplasia). The orthotopic dysplasia group showed more ILC3 percentage than the other groups. CONCLUSION ILC1 and ILC3 subgroups increased significantly in reparative and dysplastic experimental CRC respectively. Thus ILC1 may have an inhibitory effect on tumor growth whereas ILC3 promotes tumor progression.","PeriodicalId":54921,"journal":{"name":"Iranian Journal of Immunology","volume":"19 4","pages":"339-348"},"PeriodicalIF":0.9,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10537169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The role of vitamin D has been demonstrated in the function of the immune system.</p><p><strong>Objective: </strong>To assess the percentage and function of CD3+ T cells and their relationship with the level of the serum vitamin D or 1,25-dihydroxy vitamin D3 (the active form of the vitamin) in women with RSA and RIF.</p><p><strong>Methods: </strong>In this case-control study, peripheral blood was obtained from the patient and the healthy control groups. The ratio of CD3+T cell and activated CD3+ CD69+T cell was investigated using flow cytometry. The serum levels of Interferon-γ (IFN-γ) and vitamin D were measured by ELISA.</p><p><strong>Results: </strong>The mean proportion of CD3+T cells in women with RSA increased significantly compared with the healthy control group (p<0.04). However, no significant difference was observed in RIF women compared with the control group. There was no significant difference in the ratio of activated CD3+CD69+T cells between the patient and the healthy control groups. Serum IFN-γ levels in women with RSA showed a significant increase compared to the control group (p<0.031); however, no significant difference was observed between women with RIF and the control group. Serum levels of vitamin D showed a significant reduction in both RSA (p<0.01) and RIF (p<0.04) groups in comparison with the control.</p><p><strong>Conclusion: </strong>An increase in the percentage and inflammatory function of T cells was associated with RSA. Decreased vitamin D levels may contribute to immune dysfunction and pregnancy loss.</p>","PeriodicalId":54921,"journal":{"name":"Iranian Journal of Immunology","volume":"19 4","pages":"369-377"},"PeriodicalIF":0.9,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10457290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
