Purpose The voltage-gated potassium channel K V 1.3 is upregulated on pro-inflammatory microglia, and its blockade is effective in reducing neuroinflammation in vitro and in vivo. The most potent and selective K V 1.3 blockers identified to date are disulfide-rich, venom-derived peptides, which are largely excluded from the brain by the blood–brain barrier (BBB). As BBB shuttle peptides have been reported to promote receptor-m...

Background Iron overload is implicated in many neurodegenerative diseases, where there is also blood–brain barrier (BBB) dysfunction. As there is a growing interest in the role of iron in modulating key BBB proteins, this study assessed the effect of iron on the expression and function of P-glycoprotein (P-gp), breast cancer resistance protein (BCRP) and claudin-5 in primary mouse brain endothelial cells (MBECs) and their abun...
