Altered membrane physiology in Müller glial cells after transient ischemia of the rat retina.

abstract：:Neuronal injury in CNS tissues induces a rapid activation and mobilization of resident microglia (MG). It is widely assumed that changes in gene expression drive the morphological transformation of MG and regulate their mobilization during activation. Here, we used acutely excised neonatal rat brain slices to test whe...
