Astrocyte-specific expression of cerebellar αTTP. Primary cerebellar cells were stained with specific antibodies directed against αTTP (green) and the astrocyte marker glial fibrillary acidic protein (GFAP) (red, upper panel) or the neuronal marker β-tubulin III (red, lower panel). Note that αTTP and GFAP (yellow) localize to the same cells. From “Vitamin E Is Essential for Purkinje Neuron Integrity,” L. Ulatowski, G. Warrier, R. Sultana, D.A. Butterfield, R. Parker, & D.
