6-hydroxydopamine induces the loss of the dopaminergic phenotype in substantia nigra neurons of the rat. A possible mechanism for restoration of the nigrostriatal circuit mediated by glial cell line-derived neurotrophic factor.

Abstract excerpt

Intraparenchymal injections of the neurotoxin 6-hydroxydopamine (6-OHDA) into the medial forebrain bundle in rats destroys the dopaminergic neurons in the pars compacta of the substantia nigra. In other transmitter systems it has been found that axotomy or neurotoxin exposure produces an initial loss of neurotransmitter phenotype, with cell death occurring over a much slower time course. To determine whether this...
