We investigated whether microglia form gap junctions with themselves, or with astrocytes, oligodendrocytes, or neurons in vivo in normal mouse brains, and in pathological conditions that induce microglial activation - brain injury and a model of Alzheimer's disease. Although microglia are in close physical proximity to glia and neurons, they do not form functional gap junctions under these pathological conditions.
