Abstract

The pathogenesis of Inflammatory Bowel Disease (IBD) involves complex mechanisms, including immune dysregulation, gut microbiota imbalances, oxidative stress, and defects in the gastrointestinal mucosal barrier. Current treatments for IBD often have significant limitations and adverse side effects, prompting a search for alternative therapeutic strategies. Natural products with anti-inflammatory and antioxidant properties have demonstrated potential for IBD management. There is increasing interest in exploring food industry waste as a source of bioactive molecules with healthcare applications. In this study, a co-culture system of Caco-2 cells and PMA-differentiated THP-1 macrophages was used to simulate the human intestinal microenvironment. Inflammation was induced using TNF-α and IFN-γ, followed by treatment with Saffron Petal Extract (SPE). The results demonstrated that SPE significantly attenuated oxidative stress and inflammation by downregulating the expression of pro-inflammatory mediators such as iNOS, COX-2, IL-1β, and IL-6 via modulation of the NF-κB pathway. Given that NF-κB is a key regulator of macrophage-driven inflammation, our findings support further investigation of SPE as a potential complementary therapeutic agent for IBD treatment.

藏红花花瓣提取物对 Caco-2/ 人白血病单核细胞共培养模型中细胞因子诱导的氧化应激和炎症的生物反应
炎症性肠病(IBD)的发病机制复杂,包括免疫失调、肠道微生物群失衡、氧化应激和胃肠道粘膜屏障缺陷。目前治疗 IBD 的方法往往有很大的局限性和不良副作用,这促使人们寻找替代治疗策略。具有抗炎和抗氧化特性的天然产品已被证明具有治疗 IBD 的潜力。越来越多的人开始关注将食品工业废弃物作为生物活性分子的来源,并将其应用于医疗保健领域。本研究使用 Caco-2 细胞和 PMA 分化的 THP-1 巨噬细胞共培养系统模拟人类肠道微环境。用 TNF-α 和 IFN-γ 诱导炎症,然后用藏红花花瓣提取物(SPE)处理。结果表明,SPE 通过调节 NF-κB 通路,下调了 iNOS、COX-2、IL-1β 和 IL-6 等促炎介质的表达,从而显著减轻了氧化应激和炎症反应。鉴于NF-κB是巨噬细胞驱动的炎症的关键调节因子,我们的研究结果支持进一步研究SPE,将其作为治疗IBD的潜在辅助治疗药物。

期刊介绍: Antioxidants (ISSN 2076-3921), provides an advanced forum for studies related to the science and technology of antioxidants. It publishes research papers, reviews and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
