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 .
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.
The receptors can both bind all three forms of IL-1 (IL-1 alpha, IL-1 beta and IL-1 receptor antagonist). The crystal structures of IL1A and IL1B [ 9 ] have been solved, showing them to share the same 12-stranded beta-sheet structure as both the heparin binding growth factors and the Kunitz-type soybean trypsin inhibitors.

The three populations of astrocyte subtypes which have been identified are: 1) dorsally located VA1 astrocytes, derived from p1 domain, express PAX6 and reelin; 2) ventrally located VA3 astrocytes, derived from p3, express NKX6.1 and SLIT1; and 3) intermediate white-matter located VA2 astrocyte, derived from the p2 domain, which express PAX6 ...
Interleukin 6 (acronym: IL-6) is a cytokine that is important for many aspects of cellular biology including immune responses, cell survival, apoptosis, as well as proliferation. [4] Several studies have outlined the importance of autocrine IL-6 signaling in lung and breast cancers.
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.
The complex of Interleukin-6 and the Interleukin-6 receptor associate with a second receptor protein called gp130, which dimerises and initiates intracellular signal transduction. [3] Gp130 is expressed on all cells of the human body whereas the Interleukin-6 receptor is only found on few cells such as hepatocytes and some leukocytes. [4]
The sheath can be even thicker if multiple SGCs are layered on top of one another, each measuring 0.1 micrometres (3.9 × 10 −6 in). [ 9 ] Despite their flattened shape, satellite glial cells contain all common organelles necessary to make cellular products and to maintain the homeostatic environment of the cell.
