Figure 2. Electron microscopic localization of PDYN in Stratum lucidum of CA3 region in rat hippocampal formation. PDYN-IR is localized within a mossy fiber terminal containing several dense core vesicles (DCV) and numerous small synaptic vesicles (SSV). Labeled terminal forms synapses (curved arrows) on multiple dendritic spines and an unlabeled dendritic shaft (uD). PDYN-IR granules are most prevalent near presynaptic plasma membranes at synapse on unlabeled dendrite. Bar = 500 nm.
