Abstract

Nanoparticles have been used in neurological research in recent years because of their blood-brain barrier penetration activity. However, their potential neuronanotoxicity remains a concern. In particular, microglia, which are resident phagocytic cells, are mainly exposed to nanoparticles in the brain. We investigated the changes in lysosomal function in silica-coated magnetic nanoparticles containing rhodamine B isothiocyanate dye [MNPs@SiO(RITC)]-treated BV2 murine microglial cells. In addition, we analyzed amyloid beta (Aβ) accumulation and molecular changes through the integration of transcriptomics, proteomics, and metabolomics (triple-omics) analyses. Aβ accumulation significantly increased in the 0.1 μg/μl MNPs@SiO(RITC)-treated BV2 cells compared to the untreated control and 0.01 μg/μl MNPs@SiO(RITC)-treated BV2 cells. Moreover, the MNPs@SiO(RITC)-treated BV2 cells showed lysosomal swelling, a dose-dependent reduction in proteolytic activity, and an increase in lysosomal swelling- and autophagy-related protein levels. Moreover, proteasome activity decreased in the MNPs@SiO(RITC)-treated BV2 cells, followed by a concomitant reduction in intracellular adenosine triphosphate (ATP). By employing triple-omics and a machine learning algorithm, we generated an integrated single molecular network including reactive oxygen species (ROS), autophagy, lysosomal storage disease, and amyloidosis. In silico analysis of the single triple omics network predicted an increase in ROS, suppression of autophagy, and aggravation of lysosomal storage disease and amyloidosis in the MNPs@SiO(RITC)-treated BV2 cells. Aβ accumulation and lysosomal swelling in the cells were alleviated by co-treatment with glutathione (GSH) and citrate. These findings suggest that MNPs@SiO(RITC)-induced reduction in lysosomal activity and proteasomes can be recovered by GSH and citrate treatment. These results also highlight the relationship between nanotoxicity and Aβ accumulation.

摘要

近年来,由于纳米粒子具有穿透血脑屏障的活性,因此在神经科学研究中得到了广泛应用。然而,其潜在的神经毒性仍然令人担忧。特别是小胶质细胞,作为驻留的吞噬细胞,主要暴露于大脑中的纳米粒子中。我们研究了含罗丹明 B 异硫氰酸酯染料[MNPs@SiO(RITC)]的二氧化硅涂层磁性纳米粒子处理的 BV2 小鼠小胶质细胞中溶酶体功能的变化。此外,我们通过转录组学、蛋白质组学和代谢组学(三重组学)分析的整合分析了淀粉样蛋白 β(Aβ)的积累和分子变化。与未处理的对照组和 0.01μg/μl MNPs@SiO(RITC)处理的 BV2 细胞相比,0.1μg/μl MNPs@SiO(RITC)处理的 BV2 细胞中 Aβ的积累显著增加。此外,MNPs@SiO(RITC)处理的 BV2 细胞显示溶酶体肿胀,蛋白水解活性呈剂量依赖性降低,并且溶酶体肿胀和自噬相关蛋白水平增加。此外,MNPs@SiO(RITC)处理的 BV2 细胞中的蛋白酶体活性降低,随后细胞内三磷酸腺苷(ATP)含量也随之降低。通过采用三重组学和机器学习算法,我们生成了一个包含活性氧(ROS)、自噬、溶酶体贮积病和淀粉样变性的综合单分子网络。对单三重组学网络的计算机分析预测,MNPs@SiO(RITC)处理的 BV2 细胞中 ROS 增加,自噬抑制,溶酶体贮积病和淀粉样变性加重。细胞中的 Aβ积累和溶酶体肿胀通过与谷胱甘肽(GSH)和柠檬酸共处理得到缓解。这些发现表明,GSH 和柠檬酸处理可以恢复 MNPs@SiO(RITC)诱导的溶酶体活性和蛋白酶体降低。这些结果还强调了纳米毒性与 Aβ积累之间的关系。
