ODN M362 sodium is a TLR9 agonist that acts as a vaccine adjuvant. ODN M362 sodium activates mouse splenocytes, induces apoptosis in human hepatocellular carcinoma cells, upregulates proinflammatory cytokines in human hepatocellular carcinoma cells, and inhibits the proliferation of human hepatocellular carcinoma cells. ODN M362 sodium upregulates the expression of TLR9/TLR6, activates downstream signaling pathways via IRAK4 and IRF7, and strongly amplifies antigen-specific cellular immune responses to participate in innate immune activation. ODN M362 sodium can be used in research related to hepatocellular carcinoma and breast cancer[1][2].
