Figure 5.

CRFr-labeled axon terminals in LC from control and stressed rats. A, CRFr immunogold-labeling is present in an axon terminal (CRFr-t) from a control rat and is associated with the plasma membrane (arrowheads). Also shown is an astrocytic process (asterisks) apposed to the dendrite. B, CRFr immunogold labeling (arrows) is prominently associated within the intracellular compartment in a CRFr-labeled axon terminal (CRFr-t) from a case perfused 1 h after 15-min swim stress. dcv, Dense-core vesicles; m, mitochondria. Scale bar, 0.5 μm.
