Expression of plectin in various cells types in the brain. The figure depicts plectin-expressing cells in the cerebrum (A) and cerebellum (B). (A), Particularly the abundant expression of plectin (dark brown) is a trait of cells such as astrocytes, endothelial cells, and ependymal cells at the boundaries between brain parenchyma and fluid-filled compartments; for example, arteries, capillaries, and ventricles. Besides cells at the border of the parenchyma and fluid-filled parts of the brain, neurons, oligodendrocytes, and intermittently microglia also express plectin. (B), In the cerebellum, Bergmann glia in the molecular layer (ML) and astrocytes in the granule cell layer (GCL) also express plectin; however, plectin was not detected in Purkinje cells from rat cerebellum [23]. The abundance of plectin expression in each particular cell type is denoted by the colour intensity, according to the colour scales at the bottom of each panel. PCL, Purkinje cell layer.
