摘要: With the rapid development of nanotechnologies, nanoparticles (NPs) are increasingly produced and used in many commercial products, which could lead to the contact of human blood vessels with NPs. Thus, it is necessary to understand the adverse effects of NPs to relevant cells lining human blood vessels, especially endothelial cells (ECs) that cover the lumen of blood vessels. Human umbilical vein endothelial cells (HUVECs) are among one of the most popular models used for ECs in vitro. In the present review, we discussed studies that have used HUVECs as a model to investigate the EC-NP interactions, the toxic effects of NPs on ECs and the mechanisms. The results of these studies indicated that NPs could be internalized into HUVECs by the endocytosis pathway as well as transported across HUVECs by exocytosis and paracellular pathways. Exposure of HUVECs to NPs could induce cytotoxicity, genotoxicity, eNOS uncoupling and endothelial activation, which could be explained by NP-induced oxidative stress, inflammatory response and dysfunction of organelles. In addition, some studies have also evaluated the influences of microenvironment (e.g. the presence of proteins and excessive nutrients), the physiological and/or pathological stimuli related to the diversity of ECs (e.g. shear stress, cyclic stretch and inflammatory stimuli), and the physicochemical properties of NPs on the responses of ECs to NP exposure. In conclusion, it has been suggested that HUVECs could be considered as a relatively reliable and simple in vitro model for ECs to predict and evaluate the toxicity of NPs to endothelium.

The increasing uses of nanoparticles (NPs) could lead to contact of human blood vessels to NPs, and it is necessary to assess the toxicity to endothelial cells (ECs) covering blood vessels. Human umbilical vein endothelial cells (HUVECs) are among one of the most used models for ECs. In this review, we discuss the validation of HUVECs as a model for ECs, the NP-HUVEC interaction, the toxic effects of NP to HUVECs, and the mechanisms and factors that can influence the responses.
