This Review discusses the contribution of different cytokine networks to inflammation in the central nervous system (CNS). In neuroinflammatory diseases such as multiple sclerosis, CNS-invading leukocytes produce many of the cytokines that are associated with disease. By contrast, in Alzheimer disease and other neurodegenerative diseases, tissue-resident cells are the main source of pathological cytokines.
