Surfing through the news archives on this site there is some info from 2010 about neutralising antibodies (NABs) and interferons:

I found the following recent post on a UK blog site, and it has good explanations and info on NABs and their possible impacts on interferon treatments:

Even though the people running the UK blog are very medication oriented and somewhat sceptical about impacts of diet on MS, it is an excellent site for anyone who is interested in what scientific articles are being published about many aspects of MS and its treatment :geek:
