Chemokines in the brain recruit immune cells from the blood or from within the brain. Disrupting this line of communication exacerbates disease in mouse models of Alzheimer disease (pages 432–438).


The immune system and the central nervous system (CNS) are arguably the most complex organs, and, in the past, relatively few scientists have attempted to study their interactions. This is in part because the CNS was considered immune privileged and hands-off to the immune system except for a few autoimmune and infectious diseases.
