Interleukin 6 (IL-6) is an interleukin that acts as both a pro-inflammatory cytokine and an anti-inflammatory myokine. In humans, it is encoded by the IL6 gene. [5] In addition, osteoblasts secrete IL-6 to stimulate osteoclast formation. Smooth muscle cells in the tunica media of many blood vessels also produce IL-6 as a pro-inflammatory cytokine.
Interleukin 6 (IL6), also referred to as B-cell stimulatory factor-2 (BSF-2) and interferon beta-2, is a cytokine involved in a wide variety of biological functions. [20] It plays an essential role in the final differentiation of B cells into immunoglobulin-secreting cells, as well as inducing myeloma/plasmacytoma growth, nerve cell ...
Interleukin 6 (IL6) is a potent pleiotropic cytokine that regulates cell growth and differentiation and plays an important role in immune response. Dysregulated production of IL6 and this receptor are implicated in the pathogenesis of many diseases, such as multiple myeloma , autoimmune diseases and prostate cancer .
Pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α also trigger pathological pain. [1] While IL-1β is released by monocytes and macrophages, it is also present in nociceptive DRG neurons. IL-6 plays a role in neuronal reaction to an injury. TNF-α is a well known proinflammatory cytokine present in neurons and the glia.
Interleukin-6 (IL-6) is thought to be a molecular mediator of glial scar formation. It has been shown to promote differentiation of neural stem cells into astrocytes. [ citation needed ] A monoclonal antibody, MR16-1, has been used to target and block the IL-6 receptors in rat spinal cord injury models.
Astrocytes that have been pushed into a reactive phenotype (termed astrogliosis, defined by the upregulation of among others, GFAP and vimentin [33] expression, a definition still under debate) may actually be toxic to neurons, releasing signals that can kill neurons. [34] Much work, however, remains to elucidate their role in nervous system ...
The term interleukin was initially used by researchers for those cytokines whose presumed targets are principally white blood cells (leukocytes). It is now used largely for designation of newer cytokine molecules and bears little relation to their presumed function. The vast majority of these are produced by T-helper cells.
For antibodies from the blood to reach astrocytes in the central nervous system (CNS), they must cross the BBB, the mechanism of which is not completely known. Some reports point to the metalloproteinase-2 and interleukin-6 as culprits responsible for the BBB failure. [22]
