Changes of calcium binding protein expression in spinothalamic tract neurons after peripheral inflammation

Changes of calcium binding protein expression in spinothalamic tract neurons after peripheral inflammation.

Specific neuronal populations are known to express calcium binding proteins (CBP) such as calbindin (CB), parvalbumin (PV) and calretinin (CR). These CBP can act as calcium buffers that modify spatiotemporal characteristics of intracellular calcium transients and affect calcium homeostasis in neurons. It was recently shown that changes in neuronal CBP expression can have significant modulatory ...

Pruriceptive spinothalamic tract neurons: Physiological properties

21 22 Itch of peripheral origin requires information transfer from the spinal cord to the brain for 23 perception. Here, primate spinothalamic tract (STT) neurons from lumbar spinal cord were 24 functionally characterized using in vivo electrophysiology to determine the role of these cells in 25 the transmission of pruriceptive information. 111 STT neurons were identified by antidromic 26 stimu...

Calsensin: a novel calcium-binding protein expressed in a subset of peripheral leech neurons fasciculating in a single axon tract

The mAb lan3-6 recognizes a cytosolic antigen which is selectively expressed in the growth cones and axons of a small subset of peripheral sensory neurons fasciculating in a single tract common to all hirudinid leeches. We have used this antibody to clone a novel EF-hand calcium-binding protein, calsensin, by screening an expression vector library. A full-length clone of 1.1 kb identified by th...

Possible role of protein kinase C in the sensitization of primate spinothalamic tract neurons.

The responsiveness of spinal cord nociceptive neurons to innocuous mechanical stimuli can be increased by the release of excitatory amino acids (EAAs) and peptides attributable to an injury-induced barrage of impulses. This sensitization of spinal dorsal horn neurons can also result from administration of phorbol ester by microdialysis, presumably by direct activation of protein kinase C (PKC)....
