Anti-IL-6R antibody [rhPM-1 (Tocilizumab)]

타겟 정보

Part of the receptor for interleukin 6. Binds to IL6 with low affinity, but does not transduce a signal (PubMed : 28265003). Signal activation necessitate an association with IL6ST. Activation leads to the regulation of the immune response, acute-phase reactions and hematopoiesis (PubMed : 30995492, PubMed : 31235509). The interaction with membrane-bound IL6R and IL6ST stimulates 'classic signaling', the restricted expression of the IL6R limits classic IL6 signaling to only a few tissues such as the liver and some cells of the immune system. Whereas the binding of IL6 and soluble IL6R to IL6ST stimulates 'trans-signaling'. Alternatively, 'cluster signaling' occurs when membrane-bound IL6 : IL6R complexes on transmitter cells activate IL6ST receptors on neighboring receiver cells (Probable).. Isoform 1. Signaling via the membrane-bound IL6R is mostly regenerative and anti-inflammatory (Probable). Drives naive CD4(+) T cells to the Th17 lineage, through 'cluster signaling' by dendritic cells (By similarity).. Isoform 2. Soluble form of IL6 receptor (sIL6R) that acts as an agonist of IL6 activity (PubMed : 21990364). The IL6 : sIL6R complex (hyper-IL6) binds to IL6ST/gp130 on cell surfaces and induces signaling also on cells that do not express membrane-bound IL6R in a process called IL6 'trans-signaling'. sIL6R is causative for the pro-inflammatory properties of IL6 and an important player in the development of chronic inflammatory diseases (PubMed : 21990364). In complex with IL6, is required for induction of VEGF production (PubMed : 12794819). Plays a protective role during liver injury, being required for maintenance of tissue regeneration (By similarity). 'Trans-signaling' in central nervous system regulates energy and glucose homeostasis (By similarity).. Soluble interleukin-6 receptor subunit alpha. Soluble form of IL6 receptor (sIL6R) that acts as an agonist of IL6 activity (PubMed : 21990364).
