Short-term exposure of primary cultures of cerebellar granule cells from neonatal rat brain to high concentrations of glutamate results in neuronal degeneration. We found that glutamate, before causing neuronal degeneration, induced a significant increase of Tau protein immunostaining. Time-course experiments revealed the increase ot Tau immunoreactivity to(More)
In the present study we investigated the effect of different Ca2+ entry blockers on the onset of neuronal damage induced by glutamate, kainate or alpha-amino-3-hydroxy-5-methyl-5-isoxazolo propionate (AMPA) in primary culture of rat cerebellar granule cells. We found that the dihydropyridine derivative, nifedipine used at 100 nM concentration, significantly(More)
Short-term exposure of primary cultures of cerebellar granule cells from neonatal rat brain to high concentrations of glutamate resulted in a significant increase of both immunoreactivity to and mRNA levels of tau protein. Time-course experiments revealed the increases of tau immunoreactivity and mRNA levels to be maximal 2 h after the glutamate pulse. To(More)
