After insult or trauma, astrocytes become activated and endeavor to restore the brain's delicately balanced microenvironment. An index of their activated state is that they become enlarged or hypertrophic. Ciliary neurotrophic factor (CNTF), a member of the alpha helical family of cytokines, is synthesized by astrocytes and is generally regarded to be an(More)
Studies using transgenic mice that overexpress ciliary neurotrophic factor (CNTF), direct injection of CNTF into brain parenchyma, and ectopic expression of CNTF by an adenoviral vector have demonstrated that CNTF activates astrocytes. Paradoxically, studies to date have failed to show an effect of CNTF on the expression of GFAP by cultured astrocytes.(More)
