Figure 7. Nerve terminals containing the mGlu7 receptor also express the Munc13‐1 or Munc13‐2 proteins.

Figure 7

A and B, double‐labelling pre‐embedding immunogold/HRP electron microscopy demonstrates mGlu7 immunolabelling (gold/silver‐intensified immunogold reaction) in the presynaptic AZ (white arrows) of axon terminals (at) immunopositive (HRP reaction) for Munc13‐1 (A) and Munc13‐2 (B) that make synapses with dendritic spines (S) of pyramidal cells. Scale bar: 0.5 μm. Den, dendrite.
