Abstract

AIM

Excessive exposure to 5-hydroxymethylfurfural (5-HMF), which is a common impurity in various sugar-containing products, induces serious side effects. Our previous study revealed that 5-HMF exerted immune sensitizing potential when injected into rodents. In this study, we explored 5-HMF mediated anaphylactoid reactions and its underlying molecular mechanisms.

METHODS

We investigated anaphylactoid reactions in Brown Norway (BN) rats and Institute of Cancer Research (ICR) mice to identify 5-HMF mediated anaphylactoid reactions. RBL-2H3 and P815 cell degranulation models were also established, and degranulation, enzyme-linked immunosorbent, filamentous actin (F-actin) microfilament staining, and western blot assays were performed in these cells.

RESULTS

We showed that 5-HMF induced anaphylactoid reactions by increasing blood vessel permeability in mice, and significantly elevating histamine (His) and glutathione peroxidase-1 (Gpx-1) levels in rat serum. Moreover, after incubation with 5-HMF, β-hexosaminidase (β-Hex), His, IL-4 and IL-6 levels were all significantly increased, thereby inducing cellular degranulation in RBL-2H3 and P815 cells. Finally, 5-HMF also upregulated Lyn, Syk, p38 and JNK protein phosphorylation levels.

CONCLUSIONS

Our findings suggest that 5-HMF induces anaphylactoid reactions both i and , therefore 5-HMF limits in sugar-containing products should receive more regulatory attention.

摘要

目的

过度暴露于5-羟甲基糠醛(5-HMF)会引发严重的副作用,5-羟甲基糠醛是各种含糖产品中常见的杂质。我们之前的研究表明,将5-HMF注射到啮齿动物体内时具有免疫致敏潜力。在本研究中,我们探讨了5-HMF介导的类过敏反应及其潜在的分子机制。

方法

我们在棕色挪威(BN)大鼠和癌症研究所(ICR)小鼠中研究类过敏反应,以确定5-HMF介导的类过敏反应。还建立了RBL-2H3和P815细胞脱颗粒模型,并在这些细胞中进行脱颗粒、酶联免疫吸附、丝状肌动蛋白(F-肌动蛋白)微丝染色和蛋白质印迹分析。

结果

我们发现5-HMF通过增加小鼠血管通透性诱导类过敏反应,并显著提高大鼠血清中组胺(His)和谷胱甘肽过氧化物酶-1(Gpx-)水平。此外,用5-HMF孵育后,β-己糖胺酶(β-Hex)、His、白细胞介素-4(IL-4)和白细胞介素-6(IL-6)水平均显著升高,从而诱导RBL-2H3和P815细胞发生细胞脱颗粒。最后,5-HMF还上调了Lyn、Syk、p38和JNK蛋白的磷酸化水平。

结论

我们的研究结果表明,5-HMF在体内和体外均可诱导类过敏反应,因此含糖产品中5-HMF的限量应受到更多监管关注。
