Synaptic connections of the slow adapting lingual afferent terminals in the principal trigeminal nucleus and nucleus of spinal trigeminal tract in cats;

Calbindin D-28k-containing neurons receiving visceral and somatic nociceptive information in interstitial nucleus of the spinal trigeminal tract project to the parabrachial nuclei in the rat;

AIM: To investigate the projection of the calbindin D 28k (CB) containing neurons that receive orofacial deep structures (masseter muscles) nociceptive information from the interstitial nucleus of the spinal trigeminal tract (INⅤ) directly to nucleus of the solitary tract (NTS).

In order to investigate whether neurons containing CB in the interstitial nucleus of the spinal trigeminal tract (INV) receive the orofacial somatic nociceptive information and transmit it to nucleus of the solitary tract(NTS), the triple-labeled method of FG retrograde tracing combined with FOS and CB protein immunofluorescence histochemistry was used.

Objective To explore futher the possible action of substance P (SP) fibers (SP) to spinal trigeminal caudal subnucleus (Vc) on the sensory neurotransmission.

The study of calcitonin gene related peptide in trigeminal subnucleus caudalis during experimental tooth movement;

Objective: To investigate Fos expression in the neurons of spinal cord and the trigeminal subnucleus caudalis (Vc) projecting to the subnucleus reticularis dorsalis (SRD) under peripheral noxious stimulation in the rat.

To investigate synaptic relations between the laminaⅡneurons and projecting neurons in the trigeminal subnucleus caudalis (Vc), we employ retrograde tracing and electronmicroscopy methods to examine the CB-LI and PV-LI positive synaptic connections with projecting neurons from Vc.

Connections between GABA-, L-ENK-and GlyT2-like immunoreactive terminals and neurons revealed by injection of recombinant GFP-Sindibis virus in superficial laminae of rat caudal spinal trigeminal nucleus;

After FG was stereotaxically injected into the rat DR, a large number of FG retrograde labeled cells in the dorsal horn of the cervical cord and caudal spinal trigeminal nucleus(Sp5C) were observed.

In situ hybridization histochemistry and immunohistochemical staining were used to observe preprotachykinin A (PPTA), calcitonin gene-related peptide (CGRP) and preproenkephalin (PPE) mRNAs expressions as well as theirderived peptides in the caudal spinal trigeminal nucleus (Vc) and trigeminal ganglion (TG).
