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).

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.

Distributions of phosphate-activated glutaminase (PAG)- and 5 subtypes (1, 1a ,2/3, 5 ) of metabotropic gluta-mate receptor (mGluR)-like immunoreactivities in the spinal trigeminal subnucleus caudalis (Vc) and trigeminal ganglion(TG) of the rat were examined by using a monoclonal antibody against PAG and 4 kinds of antibody against those 5 subtypesof mGluR in the present study.

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