Détail du antigène

Antigène: IL-10 (IL10) (Interleukin 10 (IL10))

Autre désignation: IL-10

Sujet: IL-10 was first described as a cytokine that is produced by T helper 2 (Th2)cell clones. It inhibits interferon (IFN)-γ synthesis in Th1 cell, and therefore it was initially called cytokine synthesis inhibiting factor(CSIF). Macrophages are the main source of IL-10 and its secretion can be stimulated by endotoxin (via Toll-like receptor 4, NF-κB dependent), tumor necrosis factor TNF-α (via TNF receptor p55, NF-κB-dependent), catecholamines, and IL-1. IL-10 controls inflammatory processes by suppressing the expression of proinflammatory cytokines, chemokines, adhesion molecules, as well as antigen-presenting and costimulatory molecules in monocytes/macrophages, neutrophils, and T cells. IL-10 inhibits the production of proinflammatory mediators by monocytes and macrophages such as endotoxin- and IFN-γ-induced release of IL-1α, IL-6, IL-8, G-CSF, GM-CSF, and TNF-α. In addition, it enhances the production of anti-inflammatory mediators such as IL-1RA and soluble TNFα receptors. IL-10 inhibits the capacity of monocytes and macrophages to present antigen to T cells. This is realized by down-regulation of constitutive and IFNγ-induced cell surface levels of MHC class II, of costimulatory molecules such as CD86 and of some adhesion molecules such as CD58.

Poids moléculaire: The 160 amino acid recombinant protein has a predicted molecular mass of 18,647 Da. The DTT-reduced protein migrates at approximately 18kDa and the non-reduced protein migrates at approximately 15kDa by SDS-PAGE. The N-terminal amino acid is Serine.
