Effects of an In Vivo Vaping Challenge on In Vitro IL-6 Biosynthesis Pathways in Arterial Endothelial Cells Derived from Human Embryonic Stem Cells
Ontology highlight
ABSTRACT: Electronic nicotine delivery system (ENDs) use among youth and young adults is increasing at a rapid pace and represents a growing public health threat.1 Newer generation devices heat e-liquids to higher temperatures and can achieve higher serum nicotine concentrations than older devices.1 Interleukin-6 (IL-6) is a cytokine that mediates atherogenesis and independently predicts future atherosclerotic cardiovascular disease events.2 Previous in vitro studies have demonstrated increased IL-6 production by human alveolar macrophages exposed to ENDs condensate.3 Although there has been considerable focus on the effects of ENDs use on airway inflammation, there are a paucity of data on the effects of ENDS on arterial inflammation. Prior in vitro studies used venous endothelial cells (VECs) or human umbilical VECs as a proxy for arterial endothelial cells (AECs), limiting generalizability of their findings. Historically, use of AECs was limited by the invasive collection methods. We used a novel in vitro AEC model of human embryonic stem-cell-derived AECs to study differential expression (DE) of IL-6 pathway genes after exposure to serum from human participants taken before and after vaping using 3rd or 4th generation ENDs or no product use.
