Nucleus-specific and differential abundance of VGLUT2 and VGLUT1 in thalamic and hypothalamic nuclei. Note high abundance of VGLUT2-ir (A) in the paraventricular thalamic nucleus (PVA), reuniens thalamic nucleus (Re), reticular thalamic nucleus (Rt), paracentral thalamic nucleus (PC), and anterodorsal thalamic nucleus (AD). Here, VGLUT1-ir (B) is almost absent or at low abundance. VGLUT1 (B) is moderately abundant in the posterior thalamic nucleus (PT) where VGLUT1 (A) is sparse. VGLUT1 is virtually absent from the stria medullaris (sm) where VGLUT2-ir is sparse. Adjacent frontal sections (C, D) of the diencephalon demonstrate the abundance of VGLUT2 (C) in the anterior hypothalamic nucleus (AH) but scarcity in the paraventricular nucleus (PVN) and extreme scarcity of VGLUT1-ir in the anterior hypothalamic nucleus (AH) and absence from the PVN. Note presence of VGLUT1 (D) but absence of VGLUT2 (C) in the ventromedial thalamic nucleus (VM). Adjacent frontal sections of the hypothalamus (E, F) demonstrate abundance of VGLUT2 in the lateral hypothalamic nucleus (LH), ventromedial hypothalamic nucleus (VMH), and dorsomedial hypothalamic nucleus (DM) and sparsity of VGLUT1 in the core of the VMH but moderate abundance in its shell. Note that VGLUT2 is less abundant in the shell and more abundant in the core of the VMH. Note some faint staining for VGLUT2 in the median eminence (ME). VGLUT1 and VGLUT2 are absent from fiber tracts of the fornix (f) and the mammillothalamic tract (mt). 3V, Third ventricle. Scale bar, 500 μm.
