SLC4A4 and stroke disorder: We detected similarly low levels of Slc4a4 (encoding NBCe1) gene expression in MG3 compared to other microglia/macrophage subpopulations, but stroke triggered a small but significant increase of Slc4a4 gene expression in the MG3 of cKO brains (1.36-fold increase, p < 0.01; Additional file 1: Figure S7).
