Despite Our Losses, People with ME/CFS Want More
We've been cheated by ME/CFS and we all know it. That's a no-brainer, if you'll pardon the cognitive pun. And loss didn't just result from the bad things that befell us. It also encompasses the good things that just ... never came. The absence of bounty. Of wholeness. Of peace.

    Tocopherol Derivative TFA-12 Promotes Myelin Repair in Experimental Models of Multiple Sclerosis.

    Multiple sclerosis (MS) is an inflammatory disease of the CNS that is associated with demyelination and axonal loss, resulting in severe neurological handicap. Current MS therapies mostly target neuroinflammation but have only a little impact on CNS myelin repair.

    Progress toward treatments that enhance remyelination would therefore represent major advances in MS treatment.

    Here, we examined the ability of TFA-12, a new synthetic compound belonging to tocopherol long-chain fatty alcohols, to promote oligodendrocyte regeneration and remyelination in experimental models of MS.

    We showed that TFA-12 significantly ameliorates neurological deficit and severity of myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis (EAE) in mice.

    Histological evaluation of mouse EAE spinal cords showed that TFA-12 treatment reduces inflammation, astrogliosis, and myelin loss.

    Additionally, we demonstrated that TFA-12 accelerates remyelination of focal demyelinated lesions induced by lysolecithin injections.

    We also found that this compound induces the differentiation of oligodendrocyte precursor cells into mature oligodendrocytes through the inhibition of the Notch/Jagged1 signalling pathway.

    Altogether, our data provide important proof of principle indicating that TFA-12 could be a potential therapeutic compound for myelin repair in MS.

    We are are all interested in remyelination. This study reports on a new drug TFA-12.

    It appears to augment remyelination in a chemical model of demyelination and in the EAE it has anti-inflammatory effects. Tocopherols (or TCP) are a class of chemical compounds of which many have vitamin E activity. Will this related compounds make it in the drug development process..along time will tell.
