Ultrastructural evidence for segregation of VGLUT3 and SERT in serotonergic axon terminals. Low-magnification electron micrographs illustrating SERT- (silver-intensified immunogold particles; thin arrows), VGLUT3- (fine diaminobenzidine (DAB) precipitate; arrowheads) or SERT/VGLUT3- (silver-intensified immunogold particles associated with fine diaminobenzidine precipitate; thick black arrows) labeled axon terminals in immature (P15) (A–D) and adult (P60) (E–H) wild-type (WT) mice of striatum (A,E), septum (B,F), ventral hippocampus (C,G) and dorsal hippocampus (D,H). m: mitochondria, ut: unlabeled terminal. Magnification: 13,500× , Scale bar: 500 nm.
