Rat Cerebellar Granule Cell Line (Cb-E1A)

Cb-E1A cell line from postnatal day 7 rat cerebellar granule cells that were immortalized with the 12S E1A adenovirus gene.


  • Excellent model system for differentiated cerebellar granule neurons
  • Express higher levels of neuronal markers (neurofilament and neuron-specific enolase) under depolarizing conditions
  • Demonstrate glutamate immunoreactivity and are sensitive to glutamate toxicity
  • Posses neomycin resistance and immunoreactivity to 12S E1A

Granule cells of the cerebellum are among the smallest neurons in the brain as well as the most abundant. They account for about 3/4 of the brain's neurons. Granule cells receive excitatory input from mossy fibers (major imputs to the cerebellum) originating from pontine nuclei.
