Missing link between brain and immune system?

There are several reports like this . Lot of the coverage seems to come from the university publicity department. Following up I came upon this reddit thread. There has been ongoing research for some time related to the vagus nerve as the second comment in the thread indicated and this article posted earlier. Along the thread, I noticed this comment:

this may be true, but the lab that published this is notorious in the field for doing bad work and publishing articles for the sake of publishing. seehttp://www.nature.com/nature/journal/v521/n7552/full/nature14444.html to read an article published last week, authored by much of the rett syndrome community, in direct opposition to a very famous paper by kipnis three years ago which promised to cure rett syndrome. kipnis' specialty is sensational science that will make it to the front page of reddit, true or not"
