Dopaminergic neurons express DGL-α in the mouse ventral tegmental area. A) A dendrite of a dopaminergic neuron identified by tyrosine hydroxylase (TH)-immunostaining (dTH) is immunolabeled for DGL-α indicated by the presence of silver intensified immunogold particles (arrows) on the plasma membrane. Remarkably, immunogold particles are predominantly present at the perisynaptic annulus of synaptic specializations (arrowheads) formed by immunonegative axon terminals (b). B–C) DGL-α (arrows) is also present in small diameter TH-positive dendrites (dTH) receiving synaptic contacts (arrowheads) from unlabeled boutons (b). Scale bars: A–C, 0.5μm.
