功能性表达血脑屏障(BBB)特性的内皮细胞是研究血脑屏障处白细胞-内皮细胞相互作用的有用替代物。在这项研究中,我们比较了两种不同的内皮细胞模型:转染人脑微血管内皮细胞(THBMEC)和人脐静脉内皮细胞(HUVECs)。随着在最佳条件下的每次生长,汇合的THBMEC培养物显示出连续的闭合蛋白和ZO-1免疫反应性,而HUVEC培养物仅在细胞-细胞接触部位显示点状ZO-1表达。在24孔胶原包被的transwell插入物上汇合的THBMEC培养物具有比HUVEC显著更高的跨内皮电阻(TEER)和更低的溶质渗透性。融合的THBMEC比HUVEC对单核细胞迁移的限制性更强。尽管THBMEC和HUVEC都使用CCL 3来促进T细胞迁移,但只有THBMEC使用近腔CCL 5来促进体外T淋巴细胞迁移。这些数据建立了使用THBMEC开发用于研究神经炎症期间白细胞-内皮相互作用的体外BBB模型的基线条件。
Endothelial cells that functionally express blood brain barrier (BBB) properties are useful surrogates for studying leukocyte-endothelial cell interactions at the BBB. In this study, we compared two different endothelial cellular models: transfected human brain microvascular endothelial cells (THBMECs) and human umbilical vein endothelial cells (HUVECs). With each grow under optimal conditions, confluent THBMEC cultures showed continuous occludin and ZO-1 immunoreactivity, while HUVEC cultures exhibited punctate ZO-1 expression at sites of cell-cell contact only. Confluent THBMEC cultures on 24-well collagen-coated transwell inserts had significantly higher transendothelial electrical resistance (TEER) and lower solute permeability than HUVECs. Confluent THBMECs were more restrictive for mononuclear cell migration than HUVECs. Only THBMECs utilized abluminal CCL5 to facilitate T-lymphocyte migration in vitro although both THBMECs and HUVECs employed CCL3 to facilitate T cell migration. These data establish baseline conditions for using THBMECs to develop in vitro BBB models for studying leukocyte-endothelial interactions during neuroinflammation.
