Interleukin-6 (IL-6) is a cytokine originally identified almost 30 years ago as a B-cell differentiation factor, capable of inducing the maturation of B cells into antibody-producing cells. As with many other cytokines, it was soon realized that IL-6 was not a factor only involved in the immune response, but with many critical roles in major physiological(More)
Interleukin-6 (IL-6) is a major cytokine which controls not only the immune system but also exhibits many other functions including effects in the central nervous system (CNS). IL-6 is known to be produced by different cells in the CNS, and all the major CNS do respond to IL-6, which makes it difficult to dissect the specific roles of each cell type when(More)
IL-6 is implicated in the pathogenesis of various neuroinflammatory and neurodegenerative disorders of the CNS. IL-6 signals via binding to either the membrane bound IL-6Rα (classic signaling) or soluble (s)IL-6Ra (trans-signaling) that then form a complex with gp130 to activate the JAK/STAT signaling pathway. The importance of classic versus(More)
Interleukin (IL)-6 is crucial for the induction of many murine models of autoimmunity including experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. While IL-6-deficient mice (IL-6 KO) are resistant to EAE, we showed previously that in transgenic mice with astrocyte-targeted production of IL-6-restricted to the cerebellum(More)
Interleukin-6 (IL-6) is a major cytokine in the central nervous system, secreted by different brain cells and with roles in a number of physiological functions. We herewith confirm and expand the importance of astrocytic production of and response to IL-6 by using transgenic mice deficient in astrocytic IL-6 (Ast-IL-6 KO) or in its receptor (Ast-IL-6R KO)(More)
Interleukin-6 (IL-6) is a multifunctional cytokine that not only plays major roles in the immune system, but also serves as a coordinator between the nervous and endocrine systems. IL-6 is produced in multiple cell types in the CNS, and in turn, many cells respond to it. It is therefore important to ascertain which cell type is the key responder to IL-6(More)
