ODN 2216 sodium
Based on 1 publication(s) in Google Scholar
ODN 2216 sodium is a type A CpG oligodeoxynucleotide vaccine adjuvant and a TLR9 agonist. ODN 2216 sodium interacts with TLR9 in the lysosomes of CD4+ T cells and activates feedback-dependent signaling pathways. ODN 2216 sodium induces the production of type I interferons, IL-6 and TGF-β via the IRAK4/IRF7 axis, while increasing intracellular ATP levels. ODN 2216 sodium not only induces the differentiation of CD4+ T cells into anti-inflammatory Th3-like regulatory phenotypes to inhibit autologous proliferation, but also enhances the specific CD8+ T cell-mediated cytotoxicity against Mammaglobin-A in breast cancer cells. ODN 2216 sodium is widely used in studies related to breast cancer and systemic lupus erythematosus.

ODN 2216 (sodium) (10 μM; 16 h pre-treatment, 9 days co-culture, 48 h cytotoxicity assay) does not significantly enhance MamA2.1-specific activation of primary HLA-A2+ CD8+ T cells or subsequent MamA-specific cytotoxicity against AU565 breast cancer cells compared to MamA2.1 peptide alone[1].
ODN 2216 (sodium) (3 μM; 24 h) induces TLR9-mediated IFN-α secretion by human PBMCs after 24 hours of incubation at a concentration of 3 μM[2].
ODN 2216 (sodium) (0.5-10 μM; 4 days) dose-dependently increases intracellular ATP and IL-6 levels in human PBMCs[2].
ODN 2216 (sodium) (500 ng/mL; 14 hours) physically interacts with intracellular TLR9 in lysosomes of human CD4+ CD25- T cells following 14-hour incubation with 500 ng/mL ODN 2216 FITC[3].
ODN 2216 (sodium) (500 ng/mL; 72 hours) induced increased proliferation of human CD4+ CD25- T cells, which is dependent on TLR9 signaling via TLR9, MyD88, IRAK1, and TRAF3, but not IRF7[3].
ODN 2216 (sodium) (500 ng/mL; 48 hours) treated human CD4+ CD25- T cells acquire dose-dependent suppressive activity against untreated autologous CD4+ T cells, with maximum suppression (48.57%) at a 4:1 suppressor:responder ratio[3].
