Utilizing the BV2 microglial cell line, they reported induction of Abcc8/Sur1 and Kcnj11/Kir6.2 following exposure to LPS + IFNγ for 48 h, as well as enhanced immunolabeling of microglia in vivo for subunits of Sur1-Kir6.2 (KATP) in cerebral ischemia. This evidence concerns the gene KCNJ11 and brain ischemia.
