Agatolimod ((ODN 2006, PF-3512676, CpG 7909)) is a TLR9 agonist and immunomodulator with an EC50 of 180 nM against human TLR9. Agatolimod activates and upregulates the expression of both TLR9 and TLR6, and mediates downstream signaling pathways via IRAK4, IRF5, IRF7. Agatolimod induces Th1-type innate and adaptive immune responses, activates various immune cells and promotes antigen presentation, regulates antibody levels and immune cell infiltration, upregulates the secretion of multiple cytokines, induces apoptosis and cell cycle arrest, enhances cytotoxicity, and clears intracellular Salmonella. Agatolimod is applicable to research on COVID?19, breast cancer, lung adenocarcinoma, HPV-related tumors, melanoma, and salmonellosis[1][2][3][4][5].
