ODN 1018
Based on 2 publication(s) in Google Scholar
ODN 1018 (1018 ISS) is a TLR9 agonist and immune modulator. ODN 1018 exhibits adjuvant activity and augments CD8+ T cell responses with LNP-encapsulated OVA peptides. ODN 1018 triggers sustained suppression of allergic airway inflammation. ODN 1018 can be used for the research of allergic asthma and systemic lupus erythematosus.

Biological Activity

TLR9 |
ODN 1018 (0.7 μM) stimulates proliferation and IL-6 production in purified human B cells, and this stimulation is inhibited by IRS at 0.35-0.7 μM[3].
ODN 1018 (0.7 μM; 48 h) activates mouse splenocytes to produce IL-6 via TLR9, and this activation is dose-dependently inhibited by IRS 869 at 0.0875-0.7 μM[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
ODN 1018 (20 μg; intranasally; weekly; 1-17 weeks) induces sustained suppression of allergic airway inflammation in ragweed-sensitized mice, with 5 weekly doses sufficient for durable effects associated with TReg induction[2].
ODN 1018 (50 μg; s.c.) induces a lethal TLR9-mediated inflammatory response in D-galactosamine-pretreated BALB/c mice[3].
ODN 1018 (25 μg; s.c.) stimulates TLR9-mediated cytokine (IL-6, IL-12) production in BALB/c mice[3].

Animal Model:BALB/c (6-8 week old female, ragweed-sensitized allergic asthma model)[2]
-
Dosage:20 μg
-
Administration:intranasally; weekly; 1, 3, 5, 8, 12, 13, 16, or 17 weeks
-
Result:Suppressed bronchoalveolar lavage (BAL) eosinophilia, BAL IL-4, IL-5, IL-13 levels, and lung Th2-associated genes (Il13, Ccl11, Gob5, Fizz1) through 13 subsequent weekly ragweed exposures (12 weekly treatments).
Induced significant, lasting reduction of Th2-mediated responses (5 weekly treatments); Upregulated lung regulatory T cell (TReg)-associated genes (Foxp3, Il10, Tgfb1, Lag3, Tnfrsf4, Il2ra) and increased TReg activity (CD4+CD25+ T cells from treated mice suppressed CD4+CD25- T cell proliferation more effectively than those from ragweed-only mice) (16 weekly treatments).
Induced a moderate Th1 shift (progressive increase in lung Ifng, Cxcl9, Cxcl10 expression) but Th2 suppression did not require IFN-γ; Prevented ragweed-pulsed bone marrow dendritic cells from restoring Th2 responses.
