IHC image of S100A9 staining in Human Tonsil formalin fixed paraffin embedded tissue section, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab63818, 0.1 μg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

ICC/IF image of ab63818 stained MCF7 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions.

補足情報

This supplementary information is collated from multiple sources and compiled automatically.

S100A9 also known as calgranulin B or MRP-14 is a calcium-binding protein with a molecular weight of approximately 13 kDa. It belongs to the S100 family and forms part of a heterodimeric complex with S100A8. S100A9 is largely found in myeloid cells such as neutrophils and monocytes. It plays a significant role in the cytosol and can be secreted to the extracellular space under specific stress conditions.
Biological function summary

S100A9 impacts inflammatory responses and immune regulation. It partners with S100A8 to form the calprotectin complex which acts as a strong pro-inflammatory mediator. This complex binds to receptors like RAGE and TLR4 initiating signaling pathways that promote inflammation. S100A9 also participates in leukocyte recruitment and has antimicrobial properties blocking the growth of bacteria and fungi by chelating essential metal ions.

Pathways

Several are influenced by S100A9 including the NF-kB and MAPK signaling pathways. Through its interaction with RAGE and TLR4 receptors S100A9 influences the activation of these pathways which are important in the regulation of inflammatory and immune responses. Other proteins involved in these pathways include MyD88 for TLR4 signaling and various kinases for MAPK signaling positioning S100A9 as an important regulator within the inflammatory networks.

S100A9 links to various inflammatory and autoimmune conditions such as rheumatoid arthritis and inflammatory bowel disease. Increased levels of S100A9 have been observed in these conditions where it augments the inflammatory response. In rheumatoid arthritis for example S100A9 upregulation correlates with increased joint inflammation and damage. The protein’s interaction with S100A8 in these diseases highlights its contribution to the pathogenesis and progression of inflammation-related conditions.

ターゲットの情報

S100A9 is a calcium- and zinc-binding protein which plays a prominent role in the regulation of inflammatory processes and immune response (PubMed : 12626582, PubMed : 15331440, PubMed : 16258195, PubMed : 19122197, PubMed : 20103766, PubMed : 21325622, PubMed : 8423249). It can induce neutrophil chemotaxis, adhesion, can increase the bactericidal activity of neutrophils by promoting phagocytosis via activation of SYK, PI3K/AKT, and ERK1/2 and can induce degranulation of neutrophils by a MAPK-dependent mechanism (PubMed : 12626582, PubMed : 15331440, PubMed : 20103766). Predominantly found as calprotectin (S100A8/A9) which has a wide plethora of intra- and extracellular functions (PubMed : 16258195, PubMed : 19122197, PubMed : 8423249). The intracellular functions include : facilitating leukocyte arachidonic acid trafficking and metabolism, modulation of the tubulin-dependent cytoskeleton during migration of phagocytes and activation of the neutrophilic NADPH-oxidase (PubMed : 15331440, PubMed : 21325622). Participates also in regulatory T-cell differentiation together with CD69 (PubMed : 26296369). Activates NADPH-oxidase by facilitating the enzyme complex assembly at the cell membrane, transferring arachidonic acid, an essential cofactor, to the enzyme complex and S100A8 contributes to the enzyme assembly by directly binding to NCF2/P67PHOX (PubMed : 15642721, PubMed : 22808130). The extracellular functions involve pro-inflammatory, antimicrobial, oxidant-scavenging and apoptosis-inducing activities (PubMed : 19534726, PubMed : 8423249). Its pro-inflammatory activity includes recruitment of leukocytes, promotion of cytokine and chemokine production, and regulation of leukocyte adhesion and migration (PubMed : 15598812, PubMed : 21487906). Acts as an alarmin or a danger associated molecular pattern (DAMP) molecule and stimulates innate immune cells via binding to pattern recognition receptors such as Toll-like receptor 4 (TLR4) and receptor for advanced glycation endproducts (AGER) (PubMed : 19402754). Binding to TLR4 and AGER activates the MAP-kinase and NF-kappa-B signaling pathways resulting in the amplification of the pro-inflammatory cascade (PubMed : 19402754, PubMed : 22804476). Has antimicrobial activity towards bacteria and fungi and exerts its antimicrobial activity probably via chelation of Zn(2+) which is essential for microbial growth (PubMed : 19087201). Can induce cell death via autophagy and apoptosis and this occurs through the cross-talk of mitochondria and lysosomes via reactive oxygen species (ROS) and the process involves BNIP3 (PubMed : 19935772). Can regulate neutrophil number and apoptosis by an anti-apoptotic effect; regulates cell survival via ITGAM/ITGB and TLR4 and a signaling mechanism involving MEK-ERK (PubMed : 22363402). Its role as an oxidant scavenger has a protective role in preventing exaggerated tissue damage by scavenging oxidants (PubMed : 21912088, PubMed : 22489132). Can act as a potent amplifier of inflammation in autoimmunity as well as in cancer development and tumor spread (PubMed : 16258195). Has transnitrosylase activity; in oxidatively-modified low-densitity lipoprotein (LDL(ox))-induced S-nitrosylation of GAPDH on 'Cys-247' proposed to transfer the NO moiety from NOS2/iNOS to GAPDH via its own S-nitrosylated Cys-3 (PubMed : 25417112). The iNOS-S100A8/A9 transnitrosylase complex is proposed to also direct selective inflammatory stimulus-dependent S-nitrosylation of multiple targets such as ANXA5, EZR, MSN and VIM by recognizing a [IL]-x-C-x-x-[DE] motif (PubMed : 25417112).
