However, there was an issue regarding immune rejection after transplantation. In this study, we established a preoperational in vitro \u201cdrug\u2013lymphocytes\u2013grafts immune reaction (Drug-LGIR)\u201d test to determine the medication for immune rejection using host immunocompetent cells (lymphocytes) and transplant cells (target iPSC-RPE cells) together with different medications. The adequacy of the test was assessed by in vivo transplantation in monkey models together with medication based on in vitro data. In the results of Drug-LGIR tests, some drugs exhibited significant suppression of RPE cell-related allogeneic reactions, while other drugs did not, and the efficacy of each drug differed among the recipient monkeys. Based on the results of Drug-LGIR, we applied cyclosporine A or local steroid (triamcinolone) therapy to two monkeys, and successfully suppressed RPE-related immune rejections with RPE grafts, which survived without any signs of rejection under drug administration. We propose that our new preoperational in vitro Drug-LGIR test, which specifies the most efficacious medication for each recipient, is useful for controlling immune attacks with personalized treatment for each patient after retinal transplantation.<\/jats:p>","DOI":"10.3390\/ijms21093077","type":"journal-article","created":{"date-parts":[[2020,4,28]],"date-time":"2020-04-28T05:05:32Z","timestamp":1588050332000},"page":"3077","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["A Strategy for Personalized Treatment of iPS-Retinal Immune Rejections Assessed in Cynomolgus Monkey Models"],"prefix":"10.3390","volume":"21","author":[{"given":"Shota","family":"Fujii","sequence":"first","affiliation":[{"name":"Laboratory for Retinal Regeneration, RIKEN Center for Biosystems Dynamics Research, 2-2-3 Minatojima-minamimachi, Chuo-ku, Kobe 650-0047, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sunao","family":"Sugita","sequence":"additional","affiliation":[{"name":"Laboratory for Retinal Regeneration, RIKEN Center for Biosystems Dynamics Research, 2-2-3 Minatojima-minamimachi, Chuo-ku, Kobe 650-0047, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoko","family":"Futatsugi","sequence":"additional","affiliation":[{"name":"Laboratory for Retinal Regeneration, RIKEN Center for Biosystems Dynamics Research, 2-2-3 Minatojima-minamimachi, Chuo-ku, Kobe 650-0047, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaaki","family":"Ishida","sequence":"additional","affiliation":[{"name":"Laboratory for Retinal Regeneration, RIKEN Center for Biosystems Dynamics Research, 2-2-3 Minatojima-minamimachi, Chuo-ku, Kobe 650-0047, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayaka","family":"Edo","sequence":"additional","affiliation":[{"name":"Laboratory for Retinal Regeneration, RIKEN Center for Biosystems Dynamics Research, 2-2-3 Minatojima-minamimachi, Chuo-ku, Kobe 650-0047, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenichi","family":"Makabe","sequence":"additional","affiliation":[{"name":"Laboratory for Retinal Regeneration, RIKEN Center for Biosystems Dynamics Research, 2-2-3 Minatojima-minamimachi, Chuo-ku, Kobe 650-0047, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Kamao","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Kawasaki Medical School, 577 Matsushima, Kurashiki, Okayama 701-0114, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuko","family":"Iwasaki","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology &amp; Visual Science, Tokyo Medical and Dental University Graduate School of Medical and Dental Sciences, 1-5-45, Yushima, Bunkyo-Ku, Tokyo 113-8510, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirokazu","family":"Sakaguchi","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Osaka University Medical School, 2-2 Yamadaoka, Suita, Osaka 565-0871, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhiko","family":"Hirami","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Kobe City Eye Hospital, 2-1-8 Minatojima-minamimachi, Chuo-ku, Kobe 650-0047, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuo","family":"Kurimoto","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Kobe City Eye Hospital, 2-1-8 Minatojima-minamimachi, Chuo-ku, Kobe 650-0047, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayo","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Laboratory for Retinal Regeneration, RIKEN Center for Biosystems Dynamics Research, 2-2-3 Minatojima-minamimachi, Chuo-ku, Kobe 650-0047, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"968","DOI":"10.1136\/bjo.87.8.968","article-title":"Trans-Tenon\u2019s retrobulbar triamcinolone infusion for the treatment of uveitis","volume":"87","author":"Okada","year":"2003","journal-title":"Br.
