An NR2B-Dependent Decrease in the Expression of trkB Receptors Precedes the Disappearance of Dopaminergic Cells in Substantia Nigra in a Rat Model of Presymptomatic Parkinson's Disease
TH and trkB immunoreactivities are highly colocalized in rat SNc. Immunofluorescent detection of TH (a) and trkB (b) in SN in untreated naïve rats. (c) Merge of (a) and (b). (a)–(c) scale bar = 150 μm. SNc: substantia nigra pars compacta; SNR: substantia nigra pars reticulata.
