✦ Synopsis
Cytokines have been recognized to play an important role both in normal development of the brain, when they act as neurotrophic factors, as well as following injury. While both the cytokines and their receptors are synthesized and expressed in the brain normally (albeit at low levels), it has become clear that elevated levels are associated with many neurological disorders. In this review, we have chosen to present the data for only a few of the cytokines, including interleukin-1, interleukin-3, interleukin-6, interferon-␥, transforming growth factor-, and tumor necrosis factor-␣. Data are presented that suggest roles they may play in human disorders, including stroke, multiple sclerosis, Alzheimer's disease, and several psychiatric disorders. The results in human disease are compared with results obtained in a variety of transgenic animal models. The mouse models have very different disorders depending on whether a cytokine is overexpressed either peripherally or in either astrocytes or neurons. The potential significance of this to the understanding of human disease is discussed.
