Focusing on the spatial dynamics of CD8<sup>+</sup> T cells could significantly advance personalized treatment strategies and the development of targeted immunotherapies in BC.</p>","PeriodicalId":19247,"journal":{"name":"NPJ Breast Cancer","volume":"11 1","pages":"13"},"PeriodicalIF":6.5,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11811209/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143390480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
