Background: S100A8

Mouse S100A8, also known as CP-10, Calgranulin A and MRP8, is a 10 kDa member of the S100 family of calcium-binding proteins (1, 2). Mouse S100A8 is an 89 amino acid protein that contains short sequential modules, including an N-terminal alpha -helix, a Ca++-binding EF-hand segment, a short central linker region, a second EF-hand segment, and a C-terminal alpha -helix. S100A8 forms homodimer, and also heterodimerizes with S100A9. In the presence of Ca++, the heterodimers form heterotetramers (3, 4). The dimeric S100 A8/A9 complex is found both intracellularly and extracellularly. It binds to heparan sulfate and is chemotactic for PMNs and macrophages. Like S100A9, S100A8 is up-regulated in neutrophils and monocytes at sites of inflammation (e.g. psoriasis, rheumatoid arthritis, cardiac ischemia) and are present at elevated concentrations in rheumatoid arthritis synovial fluid (5-7). It functions both intracellularly and extracellularly, where it binds to RAGE and CD36. In addition, S100A8 was shown to activate lung alveolar epithelial cells, osteoclasts, and chondrocytes in TLR4-dependent manner, inducing proinflammatory cytokines and chemokines including, IL-6, IL-8, KC, and MCP-1 (8-10). In osteoarthritic chondrocytes, S100A8 and A9 also promoted expression of matrix metalloproteinases (MMP-1, -3, -9, and -13) potentially affecting to cartilage breakdown (10). The amino acid sequence of mouse S100A8 is 80% and 57% identical to that of rat and human S100A8, respectively (11, 12).
