OLIG2 and tauopathy: To characterize tauopathy in the peri-infarct area of MB rats, we investigated how Tau pS396 expression was correlated with various structures, such as neurons (NeuN), astrocytes (GFAP), the myelin sheath (MBP), microtubules in the neuronal axon (MAP2), nuclei and soma of oligodendrocytes (Olig2), and the whole oligodendrocyte with dendritic processes (Oligodendrocyte) (Figure 5).
