Since June 2020, we have been working on a project to develop a therapeutic drug using receptor decoys, even though we cannot predict how long the pandemic will last or how long our daily lives will be restricted. This receptor decoy utilizes Angiotensin-converting enzyme 2 (ACE2), which is the receptor for SARS-CoV-2, and involves introducing mutations that enhance its binding ability with the spike protein of SARS-CoV-2. This high-affinity ACE2, acting as a decoy protein, is a strategy to inhibit viral infection and to expect therapeutic effects by replacing the endogeneous ACE2 that SARS-CoV-2 binds to with ACE2 decoy. This paper introduces the development of ACE2 decoys that have progressed through collaborative research with many researchers outside the field of virology.</p>","PeriodicalId":75275,"journal":{"name":"Uirusu","volume":"73 2","pages":"163-172"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142334086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because wild-type MeV is not neurotropic, the virus is thought to evolve and acquire neuropathogenicity to cause SSPE. Our recent studies have shown that MeV acquires hyperfusogenic mutations in the fusion (F) gene that confer the ability to use cell adhesion molecule 1 (CADM1) and CADM2 as cis-acting receptor mimicking molecules and allow MeV to spread in neurons. Furthermore, under these conditions, multiple MeV genomes, rather than a single one, are likely to be transmitted transsynaptically between neurons through cell-cell fusion. Therefore, F proteins encoded by different genomes are co-expressed in infected cells, and positive and negative functional interactions between them can occur. These interactions determine the ability of the virus to spread in neurons as a population. In this article, we describe our studies to understand the mechanism by which MeV acquires neuropathogenicity in SSPE.</p>","PeriodicalId":75275,"journal":{"name":"Uirusu","volume":"73 1","pages":"95-104"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142334084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is not easy to understand the overall picture of rotavirus epidemic because of the great variety of genotypes and the large inter-seasonal and regional differences in the prevalent strains. Fortunately, the rotavirus vaccines now widely used around the world are highly effective and safe. The number of rotavirus gastroenteritis cases is declining dramatically, especially in high-income countries. In Japan, rotavirus vaccines have been included in the routine vaccination program since October 2020. Additionally, the impact of the SARS-CoV-2 pandemic control measures on the rotavirus epidemic was also very significant. These synergistic effects have resulted in few rotavirus outbreaks in recent years. Nevertheless, rotavirus is unlikely to be completely eradicated, and indeed a small number of sporadic cases continue to be reported. It will continue to be important to maintain high vaccination coverage and to continuously investigate prevalent strains. This review will provide an overview of the rotavirus epidemic situation in Japan and abroad. Annual changes in domestic epidemic strains that have been revealed by steady research to date will also be presented.</p>","PeriodicalId":75275,"journal":{"name":"Uirusu","volume":"73 1","pages":"33-44"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142334078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
