Dual Role for Immune Cells in the Brain

"ScienceDaily (Jan. 16, 2010) — We all have at one time or another experienced the typical signs of an infection: the fever, the listlessness, the lack of appetite. They are orchestrated by the brain in response to circulating cytokines, the signaling molecules of the immune system. But just how cytokines' reach extends beyond the almost impenetrable blood-brain barrier has been the topic of much dispute....

n their latest study, researchers at the Salk Institute for Biological Studies describe how, depending on the nature of the stimulus, resident macrophages lined up along the blood-brain barrier play opposing roles in the transmission of immune signals into the brain.

"These macrophages act as accelerators to enlist the brain's participation in dealing with immune insults, but when necessary slam on the brakes to prevent the central inflammatory response from going overboard," explains postdoctoral researcher Jordi Serrats, Ph.D., who co-led the study with Jennifer C. Schiltz, Ph.D., formerly a postdoctoral researcher in the Salk's Neuronal Structure and Function Laboratory and now an assistant professor at the Uniformed Services University in Bethesda, Maryland...."

There's a great deal more, so much so that I intend to dissect it on my blog, but there is much of interest to those of us who suspect both inflanmmation and the BBB.
