Functional partial agonism at ionotropic excitatory amino acid receptors.

abstract：BACKGROUND:Neuronal iron accumulation is thought to be relevant to the pathogenesis of Parkinson's disease (PD), although the mechanism remains elusive. We hypothesized that neuronal iron uptake may be stimulated by functional mitochondrial iron deficiency. OBJECTIVE:To determine firstly whether the mitochondrial toxi...
