Coxsackievirus B3 (CVB3) is the most frequently implicated causative agent and has been extensively studied because of its high prevalence and severity. No specific therapeutic interventions for VM exist, and vaccine development has encountered substantial challenges. Therefore, we aimed to develop a novel CVB3 mucosal vaccine as a preventive strategy against VM. Gram-positive enhancer matrice (GEM) particles serve as innovative mucosal vaccine adjuvants and antigen delivery systems that enhance antigen immunogenicity by facilitating effective mucosal immune responses. In this study, GEM particle display technology was used to develop two novel CVB3 vaccines: (1) a GEM particle-based vaccine displaying the CVB3 capsid protein VP1 via a PA anchor protein (GEM-PA-VP1), and (2) a GEM particle-based vaccine displaying VP1 via the FcSP peptide (GEM-Fc-VP1). Both GEM-PA-VP1 and GEM-Fc-VP1 vaacines significantly elevated levels of specific IgG, IgG1, IgG2a, sIgA and neutralizing antibodies in a mouse model, along with enhanced secretion of Th1- and Th2-associated cytokines, compared to controls. Notably, GEM-Fc-VP1 demonstrated superior immunogenicity compared with that of GEM-PA-VP1, evidenced by higher antibody titres and cytokine responses. In challenge protection experiments, both vaccines significantly improved survival rates, reduced myocardial enzyme levels, and decreased inflammatory cell infiltration in myocardial tissue, with GEM-Fc-VP1 exhibiting greater efficacy. These findings establish a foundation for the development of a safe and effective CVB3 candidate vaccine and provide novel insights into the potential of peptide-mediated subunit vaccine approaches.</p>","PeriodicalId":23747,"journal":{"name":"Virulence","volume":" ","pages":"2481657"},"PeriodicalIF":5.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12080276/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143773130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To identify the DNAm sites across the epigenome that are associated with discrimination, we conducted epigenome-wide association analyses (EWAS) of three discrimination measures (everyday discrimination, race-related major discrimination, and non-race-related major discrimination) in 1,151 participants, including 565 non-Hispanic White, 221 African American, and 365 Hispanic individuals, from the Multi-Ethnic Study of Atherosclerosis (MESA).

However, some products of the reaction between UA and oxidants are not inert and, therefore, do not confer the anticipated antioxidant protection. A direct pro-oxidant effect is favoured in the one-electron oxidation of UA by heme-peroxidases yielding free radical intermediates that can initiate or propagate a radical-chain reaction. Additionally, an indirect pro-oxidant effect has been proposed by eliciting the expression or activation of enzymes that catalyse oxidant production, e.g. NADPH oxidase (NOX). This review brings together fundamental concepts and the molecular mechanisms of the redox reactions involving UA. The signature metabolites from these reactions are discussed to give valuable insights on whether these intermediates are being formed and what role they may play in disease pathogenesis.

We found that partial recovery of ventricular dysfunction, LV hypertrophy, and gene expression programmes occurred in mice under reversible transverse aortic constriction (rTAC). Gene expression analysis in cardiac myocytes identified a lasting repression of mitochondrial gene expression resulting in compromised fatty acid oxidation in the mouse model of reversible pressure overload and in human LV samples after LVAD therapy and a persistent upregulation of epigenetic and transcriptional regulators.
