Interleukin-1 beta regulates proenkephalin gene expression in astrocytes cultured from rat cortex.

abstract：:Radial glial cells play an essential role through their function as guides for neuronal migration during development. Disruption of metabotropic glutamate receptor 5 (mGluR5) function retards the growth of radial glial processes in vitro. Neuregulins (NRG) are activated by proteolytic cleavage and regulate (radial) gl...
