Abstract
We investigated the alteration of oligodendrocytes in comparison with that of astrocytes and microglia in the mouse striatum after MPTP 1methyl4phenyl1236tetrahydropridine treatment under the same conditions using Western blot analysis and Immunohistochemistry In our Western blot analysis four administrations of MPTP at 2h intervals to mice produced the remarkable loss of TH tyrosine hydroxylase protein levels in the striatum after 3 and 7 days In contrast GFAP glial fibrillary acidic protein and Iba1 protein in the striatum showed a significant increase of GFAP and Iba1 protein levels 3 and 7 days after MPTP treatment On the other hand the levels of CNPase 2′ 3′cyclic nucleotide 3′phosphodiesterase protein were decreased significantly in the striatum 3 and 7 days after MPTP treatment In our immunohistochemical study a significant decrease in the area of expression of CNPasepositive profiles was observed in the striatum 3 and 7 days after MPTP treatment
