Intestinal health is closely linked to intestinal stem cells (ISCs), which are highly sensitive to the harmful substances in the lumen. However, there is limited knowledge regarding the effects of food additives on ISCs. This study aims to investigate the impact of dietary titanium dioxide nanoparticles (TiO2 NPs) compared with titanium dioxide microparticles (TiO2 MPs) on intestinal health associated with ISCs in response to dextran sodium sulfate (DSS)-induced enteritis in mice, as well as the related mechanism. We found that exposure to 1% (w/w) TiO2 NPs aggravated DSS-induced enteritis in mice, while this effect could not be observed under exposure to TiO2 MPs. Additionally, 1% (w/w) TiO2 NPs exposure under DSS-induced enteritis worsened the ISC-mediated regeneration of intestinal epithelium by decreasing the epithelial cell proliferation and epithelial turnover rate while increasing epithelial cell death. Meanwhile, using a 3D intestinal organoid model, we discovered that 20 μg/mL TiO2 NPs impaired ISC function and disrupted ISC fate specification both ex vivo and in vitro. Furthermore, TiO2 NPs hindered the nuclear translocation of β-catenin, reducing the overall output of Wnt signaling. Together, TiO2 NPs deteriorated the intestinal epithelial regeneration of mice with DSS-induced enteritis by perturbating ISC function and fate specification through a mechanism involving Wnt signaling. These findings highlight the adverse effect of dietary TiO2 NPs on ISCs and shed light on the particle size optimization of TiO2 food additive.
肠道健康与肠道干细胞(ISC)密切相关,肠道干细胞对肠腔中的有害物质高度敏感。然而,人们对食品添加剂对肠干细胞的影响了解有限。本研究旨在探讨膳食中的二氧化钛纳米颗粒(TiO2 NPs)与二氧化钛微颗粒(TiO2 MPs)相比,在应对右旋糖酐硫酸钠(DSS)诱导的小鼠肠炎时,对与ISC相关的肠道健康的影响以及相关机制。我们发现,暴露于1%(w/w)TiO2 NPs会加重DSS诱导的小鼠肠炎,而暴露于TiO2 MPs则观察不到这种效应。此外,在DSS诱导的肠炎中暴露于1%(w/w)TiO2 NPs会使ISC介导的肠上皮再生恶化,因为它降低了上皮细胞的增殖和上皮细胞的周转率,同时增加了上皮细胞的死亡。同时,我们利用三维肠道类器官模型发现,20 μg/mL TiO2 NPs会损害ISC的功能,并破坏ISC在体内外的命运分化。此外,TiO2 NPs还阻碍了β-catenin的核转位,降低了Wnt信号的整体输出。总之,TiO2 NPs通过一种涉及Wnt信号转导的机制,扰乱了ISC的功能和命运分化,从而恶化了DSS诱导的肠炎小鼠的肠上皮再生。这些发现凸显了膳食二氧化钛纳米粒子对ISC的不利影响,并为二氧化钛食品添加剂的粒度优化提供了启示。

Engineered nanoparticles (NPs) are extensively used in the food industry, yet safety concerns remain. The lack of validated methodologies is a bottleneck towards resolving this uncertainty. Hence, the current study aims to compare two cell models by examining the toxicological impacts of two food-relevant NPs (SiO2 and Ag) on intestinal epithelia using monolayer Caco-2 cells and full-thickness 3D tissue models of human small intestines (EpiIntestinal™). Comprehensive characterization and dosimetric analysis of the NPs were performed to determine effective doses and model realistic exposures. Neither genotoxicity nor cytotoxicity were detected in the 3D tissues after NP treatment, while the 2D cultures exhibited cytotoxic response from Ag NP treatment for 24 h at 1 μg/ml. Hyperspectral imaging and transmission electron microscopy confirmed uptake of both NPs by cells in both 2D and 3D culture models. Ag NPs caused an increase in autophagy, whereas SiO2 NPs induced increased cytoplasmic vacuolization. Based on realistic exposure levels studied, the 3D small intestinal tissue model was found to be more resilient to NP treatment compared to 2D cell monolayers. This comparative approach towards toxicological assessment of food relevant NPs could be used as a framework for future analysis of NP behavior and nanotoxicity in the gut.
工程纳米粒子(NPs)被广泛应用于食品工业,但安全问题依然存在。缺乏经过验证的方法是解决这一不确定性的瓶颈。因此,本研究旨在比较两种细胞模型,使用单层 Caco-2 细胞和全厚三维人体小肠组织模型(EpiIntestinal™)检测两种与食品相关的 NPs(二氧化硅和银离子)对肠上皮细胞的毒理学影响。对 NPs 进行了全面的表征和剂量测定分析,以确定有效剂量和模拟实际暴露。经 NP 处理后,三维组织中未检测到基因毒性或细胞毒性,而二维培养物在 1 μg/ml Ag NP 处理 24 小时后表现出细胞毒性反应。高光谱成像和透射电子显微镜证实了二维和三维培养模型中细胞对两种 NPs 的吸收。Ag NPs引起自噬增加,而SiO2 NPs则诱导细胞质空泡化增加。根据所研究的实际暴露水平,发现三维小肠组织模型与二维细胞单层相比对 NP 处理更有抵抗力。这种对与食品相关的 NP 进行毒理学评估的比较方法可作为未来分析 NP 在肠道中的行为和纳米毒性的框架。

Biocides are used as preservatives in various household products, and 1,2-benzisothiazolin-3-one (BIT) is one of the popular chemicals. Therefore, BIT is highly likely to be exposed to human skin, necessitating dermal toxicity evaluation. In this study, we aimed to investigate dermal toxicity, eyes and skin irritation, and skin sensitization of BIT. All studies were conducted according to the Organisation for Economic Co-operation and Development testing guidelines. In acute dermal toxicity using rats, no treatment-related responses were observed at the highest dose (2000 mg/kg). A 28-day repeated dermal toxicity study at 1, 4, and 12 mg/kg/day showed transient local skin irritation lesions, including erythema, exfoliation, and crust formation. Based on no systemic effects, the no observed adverse effect level (NOAEL) of BIT of the 28-day repeated dermal toxicity study was determined to be 12 mg/kg/day. Eye and skin irritation tests showed that BIT is a strong irritant and corrosive to the eyes and a mild irritant to the skin. However, BIT showed no skin sensitization reactions in a local lymph node assay. These dermal toxicity studies can provide valuable information for the risk assessment of BIT.
杀菌剂被用作各种家用产品的防腐剂,1,2-苯并异噻唑啉-3-酮(BIT)是其中一种常用化学品。因此,BIT 极有可能接触到人体皮肤,因此有必要进行皮肤毒性评估。本研究旨在调查 BIT 的皮肤毒性、眼睛和皮肤刺激性以及皮肤致敏性。所有研究都是根据经济合作与发展组织的测试指南进行的。在使用大鼠进行的急性皮肤毒性试验中,最高剂量(2000 毫克/千克)未观察到与治疗相关的反应。以 1、4 和 12 毫克/千克/天的剂量进行的为期 28 天的重复皮肤毒性研究显示,出现了短暂的局部皮肤刺激症状,包括红斑、脱皮和结痂。由于未出现系统性影响,28 天重复皮肤毒性研究中 BIT 的无观测不良效应水平 (NOAEL) 被确定为 12 毫克/千克/天。眼睛和皮肤刺激测试表明,BIT 对眼睛有强烈的刺激性和腐蚀性,对皮肤有轻微的刺激性。不过,在局部淋巴结试验中,BIT 未显示皮肤过敏反应。这些皮肤毒性研究可为 BIT 的风险评估提供有价值的信息。
