Human TLR9 (Toll-Like Receptor 9) CLIA Kit

Toll-Like Receptor 9; Cd Antigen Cd289

TLR9_HUMAN ; Reactome: R-HSA-109704 ; Gene ID: 54106

Tissue Specificity: Highly expressed in spleen, lymph node, tonsil and peripheral blood leukocytes, especially in plasmacytoid pre-dendritic cells. Levels are much lower in monocytes and CD11c+ immature dendritic cells. Also detected in lung and liver.

Function: Key component of innate and adaptive immunity. TLRs (Toll-like receptors) control host immune response against pathogens through recognition of molecular patterns specific to microorganisms. TLR9 is a nucleotide-sensing TLR which is activated by unmethylated cytidine-phosphate-guanosine (CpG) dinucleotides. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Controls lymphocyte response to Helicobacter infection. Upon CpG stimulation, induces B-cell proliferation, activation, survival and antibody production.
