γH2AX reactivity in various cell types in cases with mTBI history. DNA damage is evident in peri-neuronal glial cells (a), ependymal and subependymal cells (b), oligodendrocytes of the white matter (c), and sub-pial astrocytes (d). In a, the inset shows a high power view of γH2AX-positive peri-neuronal glial cells. In b, the inset shows a healthy control case with no γH2AX reactivity in the ependymal lining for comparison. Scale bar represents 120 μm
