The role of glial cells in immune responses in the brain

Show Summary Details

Preview

Immune reactions in the brain are largely controlled by the interaction between extrinsic immuneffector cells such as T and B cells, and resident glial cell populations. T and B lymphocytes recruited from peripheral immune organs constitute the main extrinsic effector cells, while microglia and astrocytes become rapidly activated as part of an intrinsic immune defence of the brain against such an immune injury. Pathophysiologically important, myelinforming oligodendrocytes are particularly vulnerable during central nervous system (CNS) immune injury. In demyelinating diseases, like multiple sclerosis, injury to oligodendrocytes as well as to components of the CNS myelin sheath plays an important role. This chapter focuses on the involvement of these different cell types during autoimmune injury, with a particular emphasis on intercellular communication between activated glial cells and lymphocytes via cytokines and other mediators.
