生物活性:
ODN 2007, a class B CpG ODN (oligodeoxynucleotide), is a Toll-like receptor (TLR) ligand. ODN 2007 can be used as an immunomodulator, vaccine adjuvant, and enhance immune responses in mammals, fish, and humans. ODN 2007 sequence: 5'-TCGTCGTTGTCGTTTTGTCGTT-3'.

体内研究:
ODN 2007 (intraperitoneal injection, 1 μg, once) can enhance the immune response by regulating the expression of immune system-related genes in zebrafish infected withVibrio traumaticus FJ03-X2.Animal Model:Zebrafish infected with Vibrio traumaticus FJ03-X2
Dosage:1 μg
Administration:Intraperitoneal injection; once
Result:Showed a cumulative mortality rate of 15.0% in treated group while the control group reached 42.1%.Showed a significant decrease in the expression levels of all intestinal immune-related genes such as TNF、IFNg1-2、IL-1β、IL-10, especially IL-1β decreased by 99.88%.

体外研究:
ODN 2007 (1 or 5 μg/mL, 3-18 h) induces significantly chicken macrophage interferon IFN-γ and IFN-β expression. ODN 2007 (10 μg/mL, 0.5-12 h) can increase levels of phosphorylation of ERK2 and AKT, stimulate the production of NO.
