Our laboratory had previously reported increased Kv1.3 and Kir2.1 current densities in microglia acutely isolated from the infarcted, so‐called ipsilateral side, compared to microglia isolated from the contralateral side from male mice subjected to MCAO, a model of ischemic stroke (Chen et al., 2016). Here, KCNA3 is linked to ischemic stroke.
