Axotomy increases CNTF receptor mRNA in rat spinal cord.

چکیده
In order to study the role of ciliary neurotrophic factor (CNTF) and its receptor (CNTF-R) in the response of spinal cord neurons to axotomy, we measured the levels of CNTF mRNA in nerve and CNTF-R mRNA in spinal cord following transection of sciatic nerve, using reverse transcriptase PCR. We found CNTF mRNA levels in the nerve fell and that CNTF-R mRNA levels in spinal cord increased at both 1 and 7 days following transection.

Deprenyl increases synaptophysin and choline acetyltransferase in rat after sciatic nerve axotomy
Neuroprotective effect of deprenyl on motoneurons of spinal cord after axotomy of peripheral nerves such as sciatic has been well established. Deprenyl is an inhibitor of monoamine oxidase type-B (MAO-B). The main function of this agent is the release of neurotransmitters from pre-synaptic terminals. Acetylcholine is a neurotransmitter that is synthesized by choline acetyltransferase (ChAT) and...

متن کاملDeprenyl changes the expression of Trk-B and P75 NTR receptors in rat after sciatic nerve axotomy
During development many of neurons die by the phenomenon named programmed cell death or apoptosis and this reaction is regulated by neurotrophin (BDNF, NGF, NT3 and NT4/5). These neurotrophins bind to two different classes of transmembrane receptor proteins, the Trks and P75 NTR. Axotomy can induce apoptosis after birth and deprenyl is a an inhibitor of monoamineoxidase type-B and seems to act ...

متن کاملCiliary neurotrophic factor prevents retrograde neuronal death in the adult central nervous system.
The neurocytokine ciliary neurotrophic factor (CNTF) was described originally as an activity that supports the survival of neurons of the chicken ciliary ganglia in vitro. The widespread expression of CNTF and its principal binding protein, CNTF receptor alpha, in the central and peripheral nervous systems suggests a broader trophic role for this peptide. In the present study, we report that CN...
