ODN 1826 (0.05 mg; i.p.; 1, 3, 5, 8, 11, 13 days) has a strong anti-tumor growth effect in a Lewis lung cancer mouse tumor model[6].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:6-week-old male C57BL/6NTac mice; GL261 glioma or B16F10 melanoma subcutaneously implanted in posterior flanks[4].
-
Dosage:100 μg/tumor
-
Administration:Intratumoral injection; every 3 days for up to 4 treatments
-
Result:Slowed tumor growth, increased F4/80+ macrophages and B220+ B cells in tumors, with variable responses (50% mice showed prolonged stasis) (in GL261 glioma model).
Achieved complete tumor regression and induced long-term immune memory in combination with Cyclophosphamide (HY-17420).
Delayed growth but did not induce regression, with modest increases in F4/80+ macrophages and B220+ B cells in combination with Cyclophosphamide (in B16F10 melanoma model).

ODN 1826 (CpG, 500 ng per well; 24 h) significantly promoted the repolarization of M2-typed bone marrow-derived cells (BMDM), which stood for tumor-associated macrophages (TAM), with a significant increase of M1 (iNOS) and a decrease of M2 markers (Fizz1 and Mrc1).

Cytotoxicity analysis of DC 2.4 cells treated with DNA-OprF/PcrV + CpG (ODN 1826) for 24 h. CpG was functionally integrated with the DNA vaccine via physical mixing. Specifically, 10 μg of pVAX1-OprF, 10 μg of pVAX1-PcrV, and 10 μg of CpG ODN were vortex-mixed in 150 μl of 1640 medium, followed by the addition of 60 μl of transfection reagent (mass-to-volume ratio = 1:2). The mixture was incubated at room temperature for 30 min to form transfection complexes, sterilized by passage through a 0.22 μm filter, and used immediately.

Scale bar = 50 μm. These results revealed no obvious tissue pathological changes or inflammatory cell infiltration in the four treatment groups, including the DNA-OprF/PcrV + CpG group.

Human astrocytes were treated with varying concentrations of CpG oligodeoxynucleotides (0, 100, 1000, and 5000 ng/mL) for 24 h. Protein expression levels of TLR9, total NF-κB, and phosphorylated NF-κB (p-NF-κB) were analyzed by Western blot with GAPDH as loading control.
