Background: Hyperglycemia contributes to cardiovascular complications in patients with type 2 diabetes. We confirmed that high glucose (HG) induces endothelial dysfunction and cerebral ischemic injury is enlarged in diabetic mice. Stem cell-released exosomes have been shown to protect the brain from ischemic stroke. We have previously shown that endothelial progenitor cells (EPCs)-released exosomes (EPC-EXs) can protect endothelial cells from hypoxia/reoxygenation (H/R) and HG-induced injury. Here, we aim to investigate the effects of EPC-EXs on astrocytes under H/R and HG-induced injury and whether miR-126 enriched EPC-EXs (miR126-EPC-EXs) have enhanced efficacy. Methods: EPC-EX uptake and co-localization were measured by fluorescent microscopy using …

Inhalation of cadmium (Cd) has been an environmental health concern with the increase in industrial activities and smoking. Cd exposure is known to affect several organs such as lungs, kidneys, and liver. In this study, we wanted to understand if Cd inhalation exposure can affect the lungs and other organs in the body. Exosomes are extracellular vesicles secreted by all living cells and are known to carry toxicants between organs. We investigated whether Cd exposure could affect exosome biogenesis and their composition. Cd exposure did not affect the viability of A549, a lung epithelial cell line and macrophages derived from …
