Was poking around for info last night and found a few interesting things... none of this is breaking news or anything.
Bayer AG - research - Herpes virus
is a pdf of Bayer's report on developing Herpes treatments. Obviously it is heavily biased and is probably a few years old but still quite informative. For instance: two different versions of the virus hide away in the body, one typically in the inner ear/temple part of the brain and one in the spine. (sound a bit like rrms and ppms to anyone else?)
Bayer apparently broke off their anti-viral research into it's own company: Aicuris
who is developing the drug BAY 57-1293
which is dramatically more effective at treating herpes then the current anti-virals used. They are said to be moving forth into human trials soon (I've read their lead compound is in Phase 2 but am not sure if that is BAY 57-1293).
None of that is directly related to MS research, but if there is a connection and if the current anti-virals just weren't enough to touch MS... BAY 57-1293 is worth keeping an eye on.
