Here's some more info reinforcing (I think) a potential link between viruses and a subset of people with RRMS.
Subtype of MS Defined by An Activated Immune Defense Program
We conclude that the transcriptional signature of the PB cells reflects the heterogeneity of MS and defines a sub-population of RRMS patients, who exhibit an activated immune defense program that resembles a virus response program, which is supportive for a link between viruses and MS
Sounds to me like they're saying the immune system in some people with RRMS is activated to defend against a virus (or viruses). I'm not sure what that means vis a vis "auto-immune" or "not auto-immune" though. Does anyone have any ideas or comments about that?
