Single-domain antibodies (V<sub>H</sub> domains) have gained increasing interest as antigen-binding domains for CAR T-cell engineering.</div></div><div><h3>Methods</h3><div>We generated a second-generation FOLR1-specific CAR incorporating a fully human V<sub>H</sub>-only antibody and compared its <em>in vitro</em> functional activity with a MOv19-derived scFV CAR. CAR expression, memory phenotype, cytotoxicity, cytokine secretion, and exhaustion markers were evaluated following antigen stimulation. Antitumor efficacy was further assessed in 3D spheroids and repeated tumor-rechallenge assays.</div></div><div><h3>Results</h3><div>Both V<sub>H</sub>-based and scFV-based FOLR1 CAR T cells demonstrated potent and antigen-specific cytotoxicity against FOLR1-positive ovarian cancer cells. Intriguingly, FOLR1-V<sub>H</sub> CAR T cells showed lower activation and cytokine release upon initial stimulation, accompanied by reduced expression of exhaustion markers including PD-1 and LAG-3. FOLR1-V<sub>H</sub> CAR T cells preferentially preserved a central-memory phenotype and displayed superior persistence and tumor control during multiple rounds of antigen rechallenge. Both CAR formats achieved comparable cytotoxicity in 3D spheroid models.</div></div><div><h3>Conclusion</h3><div>Human FOLR1-V<sub>H</sub> CAR T cells demonstrated potent antitumor activity with reduced exhaustion and enhanced persistence. These properties highlight the V<sub>H</sub> domain as a promising targeting module for next-generation CAR T-cell therapies in ovarian cancer.</div></div>","PeriodicalId":8966,"journal":{"name":"Biomedicine & Pharmacotherapy","volume":"197 ","pages":"Article 119169"},"PeriodicalIF":7.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147322723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
