Furthermore, in active MS lesions many of which undergo remyelinationaxons express Nav1. This, together with our results, suggests a commonality of response by injured axons: the demyelinated axons undergo a similar response to that of transected peripheral axons, which by reactivating silent growth programmes revert to a minidigi 1b state for efficient regeneration Consistent with our data, OPCs are present in chronic lesions5, presumably lacking an. Thus, our results reveal a missing link for understanding myelin regeneration and open up new and pharmacologically tractable avenues by which the arrest of OPC differentiation in chronic MS lesions could be therapeutically reversed.

Toxin-induced focal demyelination. Female Sprague-Dawley rats aged weeks of age g were used.


Experiments minidigi 1b performed in compliance with UK Home Office regulations. In this toxin model, remyelination proceeds to completion between 3 and 4 weeks after induction of the lesion with a clear temporal separation between the acute demyelination phase and the subsequent stages of remyelination: OPC recruitment dpldifferentiation dpl and remyelination dpl For electrophysiological experiments, focal demyelination was induced bilaterally by injection of EB into the CCP24 and animals were culled by decapitation. minidigi 1b


After incision of the skin, holes were drilled at stereotaxically defined locations, then a Hamilton syringe lowered in place to inject 4. The skin was sutured using Minidigi 1b 5.

Analgesia was provided by injection of minidigi 1b 0. Animals were monitored twice daily until full recovery. For continuous local delivery, unilateral lesions were performed and blockers Tocrisdissolved in 0. Drug delivery into the lesion did not occur until 3 dpl the start of the OPC recruitment stage25; Fig.

The onset of drug delivery into the lesion was controlled by varying the length of the tube that connects the minipump to the cannula and by inserting a sterile corn oil drop Sigma to prevent diffusion of the drug solution into the initial saline solution. We have previously shown that the delivery is local with no significant dye diffusion detectable outside the lesion Samples were included in the analysis only if the cannula was found within mm of the lesion.
