T-cells coordinate with all immune cell types to orchestrate both cellular and antibody-mediated responses. While there is compelling evidence that PFAS alters immunity in humans, the specific effects of early life PFAS exposure on infant T-cell development are unreported. Because of their central role in immunity, altered T-cell development in infants would have implications on immune responses broadly and long-term. <b>OBJECTIVES</b>: We seek to model longitudinal changes in the frequency of functionally distinct CD4+ T-cell subpopulations from birth through 12 months and their association with in utero PFAS exposure. <b>METHODS</b>: Maternal-infant dyads were recruited as part of the UPSIDE-ECHO cohort during the first trimester between 2015 and 2019 in Rochester, New York; dyads were followed through the infant's first birthday. Maternal PFAS concentrations (PFOS, PFOA, PFNA, PFHXS and PFDA) were quantified in serum during the second trimester using high-performance liquid chromatography and tandem mass spectrometry.

PM<sub>2.5</sub> from other sources than local traffic was more strongly associated with COPD than PM<sub>2.5</sub> from local traffic, while for UFP and EC, the contributions from local traffic seemed to be the most harmful. Effect modification analyses showed stronger associations among women, never smokers, and those with an asthma diagnosis.</p><p><strong>Discussion: </strong>Our findings suggest that air pollution from local traffic and other sources contributes to COPD risk, with variations depending on the pollutant type. Further research is needed to validate these findings across different populations and geographical settings.</p>","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":"134 4","pages":"386-396"},"PeriodicalIF":10.9,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13445269/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148683929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
