The peptide inhibitor of the transendothelial migration (PEPITEM)\/cadherin (CDH) 15 axis was recently reported to promote sphingosine 1 phosphate secretion. In this study, we investigated whether CDH15 is expressed in the kidney of MRL\/lpr mice and whether lymphocyte infiltration is suppressed by exogenously administered PEPITEM. Mice (18 wk old) were randomized into 4-wk treatment groups that received PEPITEM or PBS encapsulated in dipalmitoylphosphatidylcholine liposomes. Enlargement of the kidney, spleen, and axillary lymph nodes was suppressed by PEPITEM treatment, which also blocked infiltration of double-negative T lymphocytes into the kidney and glomerular IgG\/C3 deposition, reduced proteinuria, and increased podocyte density. Immunohistochemical analysis revealed that the PEPITEM receptor CDH15 was expressed on vascular endothelial cells of glomeruli and kidney arterioles, skin, and peritoneum in lupus mice at 22 wk of age but not in 4-wk-old mice. These results suggest that PEPITEM inhibits lymphocyte migration and infiltration into the kidney, thereby preserving the kidney structure and reducing proteinuria. Thus, PEPITEM administration may be considered as a potential therapeutic tool for systemic lupus erythematosus.<\/jats:p>","DOI":"10.4049\/jimmunol.1900213","type":"journal-article","created":{"date-parts":[[2020,3,14]],"date-time":"2020-03-14T00:25:51Z","timestamp":1584145551000},"page":"2043-2052","source":"Crossref","is-referenced-by-count":11,"title":["PEPITEM\/Cadherin 15 Axis Inhibits T Lymphocyte Infiltration and Glomerulonephritis in a Mouse Model of Systemic Lupus Erythematosus"],"prefix":"10.1093","volume":"204","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9517-7746","authenticated-orcid":false,"given":"Hidehito","family":"Matsubara","sequence":"first","affiliation":[{"name":"Department of Nephrology and Endocrinology, National Defense Medical College , Tokorozawa, Saitama 359-8513 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshitaka","family":"Shimizu","sequence":"additional","affiliation":[{"name":"Department of Applied Biochemistry, Tokai University , Hiratsuka, Kanagawa 259-1207 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3496-1198","authenticated-orcid":false,"given":"Masaaki","family":"Arai","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, National Defense Medical College , Tokorozawa, Saitama 359-8513 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Yamagata","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Endocrinology, National Defense Medical College , Tokorozawa, Saitama 359-8513 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seigo","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Endocrinology, National Defense Medical College , Tokorozawa, Saitama 359-8513 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihiko","family":"Imakiire","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Endocrinology, National Defense Medical College , Tokorozawa, Saitama 359-8513 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2892-1859","authenticated-orcid":false,"given":"Masashi","family":"Tsunoda","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine and Public Health, National Defense Medical College , Tokorozawa, Saitama 359-8513 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroo","family":"Kumagai","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Endocrinology, National Defense Medical College , Tokorozawa, Saitama 359-8513 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Oshima","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Endocrinology, National Defense Medical College , Tokorozawa, Saitama 359-8513 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,4,15]]},"reference":[{"key":"2025030417511445700_r1","doi-asserted-by":"crossref","first-page":"2929","DOI":"10.1681\/ASN.2016040415","article-title":"Current and emerging therapies for lupus nephritis","volume":"27","author":"Parikh","year":"2016","journal-title":"J.
