Yes, I have seen this:
MS is an autoimmune disease in which the body's own immune response attacks the central nervous system, almost as if the body had become allergic to itself, leading to progressive physical and cognitive disability.
The new treatment, appropriately named GIFT15, puts MS into remission by suppressing the immune response. This means it might also be effective against other autoimmune disorders like Crohn's disease, lupus and arthritis, the researchers said, and could theoretically also control immune responses in organ transplant patients. Moreover, unlike earlier immune-supppressing therapies which rely on chemical pharamaceuticals, this approach is a personalized form of cellular therapy which utilizes the body's own cells to suppress immunity in a much more targeted way [...] and the treatment was fully effective with a single dose.
No, I am not excited. Two reasons. One, the experiment was with mice--mice--with a condition that isn't actually MS but an artificially-induced analogue of same. Two, if you scroll down to the end of the article you'll find this sentence: MS must be caught in its earliest stages, Galipeau cautioned... So it won't do me any fucking good.
I get really tired of reading about miracle cures. One day, perhaps, there'll be one (though frankly I doubt it). But today is not that day.
