Look under "psychneuroimmunology". There are vascular "plexus" located
in the circumventricular areas at which the BBB is thought to be less
selective. There is some evidence of active transport by vascular
endothelium in the case of IL-1; I'm not sure about IL-6. Or, IL-6
may cause the vascular endothelium in the brain to release secondary
mediators, like prostaglandins, which do cross the BBB. There is a book
called "Psychoneuroimmunology" (I think) edited by Robert Ader and Nicholas
Cohen (I think) which reviews the whole area. There are a lot of current
research and review articles in this. Try searching MEDLINE for blood
brain barrier in combination with IL-6, IL-1, and TNF-alpha.
