Unilateral up-regulation of glutamate receptors in limbic regions of amygdaloid-kindled rats.

abstract：:Insulin-like growth factor-1 (IGF-1) is an endogenous peptide transported across the blood brain barrier that is protective in several brain injury models, including an acute animal model of Parkinson's disease (PD). Motor deficits in PD are due largely to the progressive loss of nigrostriatal dopaminergic neurons. Th...
