Immunoperoxidase labeling for dopamine D2 receptor
at pre- and post-synaptic sites in the rat caudate-putamen nucleus.
Presynaptic labeling for the receptor is seen as diffuse peroxidase
immunoreactivity around membranes of small synaptic vesicles (ssv) in an
axon terminal that forms an asymmetric synapse with a dendritic spine that
also shows intense peroxidase immunoreactivity associated with the postsynaptic
membrane specialization (open arrowhead).
Another small axon terminal (D2-T) shows dark peroxidase reaction
product and is apposed to dendrite (D2-D) that has immunoperoxidase labeling
associated with tubulovesicles (tv). UD = unlabeled dendrite. Bar= 0.2 μm. |
