In this study, gelatin was extracted from tilapia ( Oreochromis niloticus ) scales by hot water extraction, followed by pepsin hydrolysis and ultrafiltration to obtain the < 3 kDa ultrafiltrated fraction of tilapia scale gelatin peptides (UTSGP). Through the evaluation of immunomodulatory activity and mechanisms, it was found that UTSGP significantly promoted the proliferation and phagocytic capacity of RAW264 . 7 macrophages. Specifically, its immunomodulatory activity was mediated by the nuclear factor‐κB (NF‐κB) pathway, which led to the increased production of tumor necrosis factor‐α (TNF‐α) and interleukin‐6 (IL‐6). In vivo studies in Caenorhabditis elegans ( C . elegans ) showed that UTSGP significantly extended lifespan, improved healthspan, and increased resistance to juglone‐induced oxidative stress. Further analysis revealed that UTSGP upregulated antioxidant genes ( sod‐3 , gst‐4 ) through the insulin/IGF‐1 signaling (IIS) pathway and enhanced innate immunity by modulating immune‐related gene expression. To our knowledge, this study is the first to demonstrate tilapia scales as a promising source of immunomodulators, showcasing the potential of their derived peptides for developing novel and efficient immunomodulatory functional foods.","PeriodicalId":513142,"journal":{"name":"Food Safety and Health","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Wine is more than just a beverage: Chemical diversity, health benefits, and immunomodulating potential of wine polyphenols","authors":"Danka Mitrović, Ivana Sredović Ignjatović, Maja Kozarski, Jelena Popović‐ Đorđević","doi":"10.1002/fsh3.12036","DOIUrl":"https://doi.org/10.1002/fsh3.12036","url":null,"abstract":"Wine, the fermented juice of the grape (Vitis vinifera), is a complex beverage composed primarily of water and ethanol. On the other hand, phenolic compounds are less abundant components that participate in taste and color formation. In addition to their major role in the sensory profile of wine, phenolic compounds (also referred as polyphenols) function through various mechanisms, exerting positive influence on health. According to recent research, consuming just one glass of red wine positively contributes to health protection, and it is connected to the maintenance of the redox endothelial balance, potential for reducing diabetes occurrence, preventing atherosclerosis, and reducing the risk of cardiovascular diseases. What is more, a lower incidence of certain types of cancers has also been observed. The health promoting benefits of wine are explained by its wide spectrum of structurally diverse phenolic compounds whose content may depend on numerous factors. The most abundant compounds are anthocyanins with up to 400 mg/L, followed by phenolic acids, flavanols, flavonols, hydrolyzable tannins, flavanones, and stilbenes (up to 200, 120, 60, 50, 25, and 5 mg/L, respectively). This review paper outlines the structural variety, health advantages, and immunomodulatory capacity of wine polyphenols, drawing upon the latest and most pertinent scientific literature available in this domain.","PeriodicalId":513142,"journal":{"name":"Food Safety and Health","volume":"85 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139774891","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}
