	Interleukin 12 Receptor, Beta 1 Subunit Interleukins (ILs) are a group of cytokines (secreted proteins and signal molecules) that are expressed and secreted by white blood cells (leukocytes) as well as some other body cells. The human genome encodes more than 50 interleukins and related proteins. The function of the immune system primarily depends on interleukins, and rare deficiencies of a number of them have been described, all featuring autoimmune diseases or immune deficiency. The majority of interleukins are synthesized by CD4 helper T-lymphocyte, as well as through monocytes, macrophages, and endothelial cells. They promote the development and differentiation of T and B lymphocytes, and hematopoietic cells. Interleukin receptors on astrocytes in the hippocampus are also known to be involved in the development of spatial memories in mice. History and name The name "interleukin" was chosen in 1979, to replace the various different names used by different research groups to designate interleukin 1 (lymphocyte act ...

	Interleukin 12 Receptor, Beta 2 Subunit Interleukin 12 receptor, beta 2 subunit is a subunit of the interleukin 12 receptor. IL12RB2 is its human gene. ''IL12RB2'' orthologs have been identified in all mammals for which complete genome data are available. The protein encoded by this gene is a type I transmembrane protein identified as a subunit of the interleukin 12 receptor complex. The co-expression of this and IL12Rβ1 proteins was shown to lead to the formation of high-affinity IL12 binding sites and reconstitution of IL12 dependent signaling. While the IL12Rβ1 subunit is constitutively expressed, the expression of the IL12RB2 gene is up-regulated by interferon gamma. In Th1 cells, IL-12 signaling through the IL12 receptor leads to the phosphorylation of STAT4 and continued Th1 differentiation. The IL12Rβ2 subunit plays an important role in Th1 cell differentiation, since its absence leads to an abortive Th1 differentiation that has dysfunctional production of Th1 effector molecules. The up-regulation of thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Type I Cytokine Receptor Type I cytokine receptors are transmembrane receptors expressed on the surface of cells that recognize and respond to cytokines with four α-helical strands. These receptors are also known under the name '' hemopoietin receptors'', and share a common amino acid motif ( WSXWS) in the extracellular portion adjacent to the cell membrane. Members of the type I cytokine receptor family comprise different chains, some of which are involved in ligand/cytokine interaction and others that are involved in signal transduction. The common cytokine-binding domain is related to the Fibronectin type III domain. Signal transduction chains The signal transducing chains are often shared between different receptors within this receptor family. * The IL-2 receptor common gamma chain (also known as CD132) is shared between: IL-2 receptor IL-4 receptor IL-7 receptor IL-9 receptor IL-13 receptor IL-15 receptor ** IL-21 receptor * The common beta chain ( CD131 or CDw131 ...

	Interleukin 12 Interleukin 12 (IL-12) is an interleukin that is naturally produced by dendritic cells, macrophages, neutrophils, and human B- lymphoblastoid cells ( NC-37) in response to antigenic stimulation. IL-12 belongs to the family of interleukin-12. IL-12 family is unique in comprising the only heterodimeric cytokines, which includes IL-12, IL-23, IL-27 and IL-35. Despite sharing many structural features and molecular partners, they mediate surprisingly diverse functional effects. Gene and structure IL12 is a heterodimeric cytokine encoded by two separate genes, IL-12A (p35) and IL-12B (p40). The active heterodimer (referred to as 'p70'), and a homodimer of p40 are formed following protein synthesis. IL12A is composed of a bundle of four alpha helices. IL12B has three beta sheet domains. Functions IL-12 is involved in the differentiation of naive T cells into Th1 cells. It is known as a T cell-stimulating factor, which can stimulate the growth and function of T cells.
