Therefore, it is of vital importance to develop a safe and effective SVA vaccine. In this study, guided by the principles of synthetic biology, we designed and synthesized two SVA candidate synthetic peptides, TT-073 and TT-074, based on the highly conserved B-cell neutralizing epitope VP2<sub>150–160aa</sub> from the SVA capsid protein, and a helper T-cell epitope derived from the F protein of the urticaria virus.

Further dual luciferase and RNA immunoprecipitation analyses showed that pZAPL targeted the ORF1, ORF2 and ORF3 mRNAs of PCV2. Overexpression of pZAPL could impact the mRNA stability of ORF1, ORF2, and ORF3. In summary, porcine ZAPL inhibits the replication of PCV2 by targeting the mRNA of ORF1, ORF2 and ORF3. The findings from this study further extend the understanding of the role of pZAP in porcine antiviral innate immunity.</div></div>","PeriodicalId":23551,"journal":{"name":"Veterinary microbiology","volume":"311 ","pages":"Article 110743"},"PeriodicalIF":2.7,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145271299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
