Why are posterior cerebellar Purkinje cells selectively vulnerable to glutamate transporter loss?

OPEN

The study identifies regional vulnerability of posterior cerebellar Purkinje cells to combined EAAT4/GLAST loss but doesn't explain the underlying basis. Understanding this selectivity could reveal fundamental principles of neuronal vulnerability in cerebellar ataxias. Gap type: unexplained_observation Source paper: Posterior cerebellar Purkinje cells in an SCA5/SPARCA1 mouse model are especially vulnerable to the synergistic effect of loss of β-III spectrin and GLAST. (None, None, PMID:28173092)
