Non-human primate studies have provided clues on the relationship between the host’s immune response and grafting success. Herein, we discuss how the host’s immune system differentially affects the graft depending on the origin of the cells and reflect on the advantages and limitations of the immune paradigms utilized to assess graft-related outcomes. We also consider new strategies to minimize or circumvent the host’s immunological response and related preclinical research needed to identify the most promising new approaches to be translated into the clinic.</div></div>","PeriodicalId":9302,"journal":{"name":"Brain Research Bulletin","volume":"224 ","pages":"Article 111297"},"PeriodicalIF":3.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143630198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
