The distribution of three vesicular glutamate transporter (VGluT) isoforms, VGluT1, VGluT2, and VGluT3, were investigated in the trigeminal ganglion of the periodontal ligament in the rat incisor-a receptive field of trigeminal ganglion neurons. In the trigeminal ganglion, mRNAs for all VGluT isoforms were detected and proteins were observed in the cytoplasm of trigeminal ganglion cells. VGluT1 immunoreactions were localized within the cytoplasm for all sizes of trigeminal neurons, although predominately in medium-large trigeminal neurons. Double-labeling showed that most VGluT1 contained both VGluT2 and VGluT3. In the periodontal ligament of the incisor, the Ruffini endings, principal periodontal mechanoreceptors, displayed VGluT1 and VGluT2 immunoreactivities. However, lacked immunoreactions for VGluT3. At the electron microscopic level, VGluT1 immunoreactions were localized around the vesicle membranes at the axon terminal of Ruffini endings. The present results indicate that VGluT is expressed in the sensory nerve endings where apparent synapses are not present. Thus, glutamate in the sensory nerve endings is thought to be used in metabotropic functions. This is because glutamate is a general metabolic substrate, and/or acts as a neurotransmitter as proposed in muscle spindles.

We have used the histochemical and immunohistochemical staining methods and maps of gene expression to analyze the structure of the inferior olive of the C57BL mouse. As in other mammals, the inferior olive of the C57BL mouse contains three major nuclei, the medial nucleus, the principal nucleus, and the dorsal nucleus. The medial nucleus can be divided into a rostral medial nucleus and a more complex caudal part, which is formed by subnuclei C, B, A, the cap of Kooy, and the beta subnucleus. The principal nucleus includes the major principal nucleus and the arcuate subnucleus. Most of the inferior olive neurons are small to medium size, the smallest of which are found in the arcuate subnucleus. Calbindin and the vesicular glutamate transporter 2 gene are expressed in nearly all inferior olive neurons, but acetylcholinesterase, glutamate decarboxylase 1 gene, cocaine- and amphetamine-regulated transcript protein prepropeptide gene, galanin gene, and calretinin are selectively expressed within different subnuclei. These findings are consistent with a pattern of extensive functional differentiation among the neuron groups of the inferior olive.
