The search for an MS vaccine continues

From August 2002 Datamonitor: "As a new approach to the treatment of MS, vaccines have the potential to be both efficacious and cost effective. But can a vaccine be developed as a viable treatment for MS? Vaccines offer an innovative therapeutic approach and may result in an expanded CNS market, but may also pose a threat to currently available drugs."

A vaccine sounds like a perfectly good idea, but wouldn't you want to know the pathogenic cause first? It's a bit like arguing over what shape and color the box will have before you know what the product does?
The way I heard it several years back, Copaxone was like a vaccine in that the drug was synthesized with certain amino acid components of the "antigenic" myelin, and you were vaccinating yourself with every shot. Sounded good to me, until I became much more amino acid educated through chem/biochem. They are looking for better peptides yes, but I agree with that already mentioned-we don't have the human MS virus or the human MS anything with complete certainty, so how do you know what vaccine will be as foolproof as smallpox?
in the original u.s. patent

#3,849,550 nov.19,'74theraputic copolymer

the developers claimed a vaccine like protection for animals treated for several days soon after challenge typically resulting in eae. these animals were protected from subsaquent attempts to give them eae even without more copolymer.

the initial dose regimens were extremely high relative to the (inadequate IMHO) dose we are given now.

i suspect the initial period of adjustment to cop-1 involves an alteration of some type to our immune systems. can't characterize it though. and i've experimented with very high doses on myself without ill effect.

so there's no reason i can see for not trying higher initial doses at least in animal experiments in order to try duplicating the very promising results described in the patent document.

this is one of the issues i hope to address when my little lab is operational.

And of course now, they're backtracking and coming up with new theories about why Copaxone works that have nothing to do with re-direction... It's good to keep in mind the disasterous Alzheimer's vaccine clinical trial that was brought to an premature halt earlier this year. Turns out maybe it's not such a good idea to incite an immune response in someone with a neurological disease (at least not in this particular way). Inciting an immune response in someone with an apparent auto immune neurological disease? I think I'll sit that trial out.
reasonable question brian

but i think it was zang at baylor who first turned things on their head by taking MSr's blood. then seperating out the leukocytes that go after MOG, MBP, PLP and any other myelin components. after getting enough of these he deactivated them by i think irradiating them. then he reinjected them prolly along with an adjuvant to stimulate an immune response.

the body learns to treat these autoimmune immune cells as invaders and destroys them. classic vaccine strategy turned on it's head using the immune system to attack itself.

the autoimmune cells become the pathogen.

there've been studies and as far as i know it's gone pretty well. it seems to require a "booster" as the immune system learns to sidestep the "banned" targets and starts eating myelin again after a while. (fwiw i call this "antigen creep") the statistical outliers ignored in the original process become the centralplayers in the autoimmune attack and require periodic re-"vaccinations".

one school of thought is to make vaccines for each individual while some groups are trying to make a one size fits all vaccine. got my doubts about the latter.

i've not followed this recently. many others have since picked up his trail. there are several groups working it now. prolly new twists i've never heard of.
