In this study, we tested the antitumor activity of a unique RIG-I agonist, stem loop RNA (SLR) 14. In the immunogenic tumor models, we observed significant tumor growth delay and an extended survival in SLR14-treated mice. SLR14 also greatly improved antitumor efficacy of anti-PD1 antibody over single-agent treatment. SLR14 was mainly taken up by CD11b⁺ myeloid cells in the tumor microenvironment, and many genes associated with immune defense were significantly up-regulated after treatment, accompanied by increase in the number of CD8⁺ T lymphocytes, NK cells, and CD11b⁺ cells in SLR14-treated tumors. Strikingly, SLR14 dramatically inhibited nonimmunogenic B16 tumor growth, and the cured mice developed an immune memory. Furthermore, a systemic antitumor response was observed in both bilateral and tumor metastasis models. Collectively, our results demonstrate that SLR14 is a promising therapeutic RIG-I agonist for cancer treatment, either alone or in combination with existing immunotherapies.</p>","PeriodicalId":23015,"journal":{"name":"The Tokushima journal of experimental medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1084/jem.20190801","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76071220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we identify a novel hematological/autoinflammatory condition (NOCARH syndrome) in four unrelated patients with superimposable features, including neonatal-onset cytopenia with dyshematopoiesis, autoinflammation, rash, and HLH. Patients shared the same de novo <i>CDC42</i> mutation (Chr1:22417990C>T, p.R186C) and altered hematopoietic compartment, immune dysregulation, and inflammation. <i>CDC42</i> mutations had been associated with syndromic neurodevelopmental disorders. In vitro and in vivo assays documented unique effects of p.R186C on CDC42 localization and function, correlating with the distinctiveness of the trait.
