Previous work in our lab demonstrated that tert-butylhydroquinone (tBHQ), a common food preservative and synthetic antioxidant, suppresses early T cell activation events, including production of interleukin-2 (IL-2) and other cytokines, cell proliferation and induction of interleukin-2 receptor alpha (CD25) and other inducible cell surface receptors. Based on these findings, the current study explores the effects of sulforaphane (SFN), a naturally-occurring antioxidant, on Jurkat T cell activation. Considering that sulforaphane exists as multiple isomers - the functional implications of which on T cells is unclear, we investigated the individual effects of SFN isomers on CD4<sup>+</sup> Jurkat T cell activation. Jurkat T cells were treated with 1, 3, 5, 10, 15, and 20 µM of either L-SFN or DL-SFN, following activation with anti-CD3/anti-CD28 for 24 h. Cell stimulation was assessed by measuring induction of activation markers using flow cytometry, and IL-2 cytokine secretion by ELISA. SFN inhibited upregulation of CD25, CD69, CD86, OX40 ligand (CD134) and CD40L (CD154) in a concentration-dependent manner. Likewise, SFN decreased induction of IL-2 secretion. Notably, both SFN isomers exhibited comparable suppressive effects on T cell activation. Taken together, these findings indicate that SFN suppresses induction of IL-2 and cell surface receptors in response to T cell stimulation, with no notable differences between isomers. These findings underscore the immunomodulatory properties of the dietary supplement SFN and specifically demonstrate inhibitory effects on T cell activation.</p>","PeriodicalId":15646,"journal":{"name":"Journal of Dietary Supplements","volume":" ","pages":"346-359"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147972979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is crucial for clinicians and consumers to be well informed about the adverse effects of such products, leading to their discontinuation and timely reporting of any harmful cases. This article delves into the clinical perspective of DS-related hepatotoxicity, highlighting key concepts such as a systematic diagnostic approach. The discussion extends to notable examples of both currently popular and potential future dietary supplements, such as garcinia cambogia, turmeric, and ashwagandha, accompanied by an overview of recent findings. Causality assessment tools play a crucial role in establishing a connection between these products and instances of liver injury, with consideration of the advantages and disadvantages associated with their use. Fostering a comprehensive understanding of regulatory standards, coupled with a solid foundation of knowledge of DS, will prove instrumental in preventing DS-related hepatotoxicity. Achieving this goal requires collaborative efforts from both consumers and clinicians.</p>","PeriodicalId":15646,"journal":{"name":"Journal of Dietary Supplements","volume":" ","pages":"58-77"},"PeriodicalIF":1.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140287561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
