First time I've seen any study work done on inflammation which referenced the role of the BBB, it's in Alzheimer's, but still...here's the link:

Now, another study came out recently refuting the role of inflammation in Alzheimer's, don't have the link, but basically they did not find inflammation in the Alz. brains they examined. They expected to find it, but did not. I'll try to find the link and post later.
