TLR7/8 Agonist 4（Cat No.:I044694）is a synthetic small-molecule immune stimulant that activates Toll-like receptors 7 and 8 (TLR7/8), key components of the innate immune system. By triggering these receptors, the compound promotes the production of pro-inflammatory cytokines, type I interferons, and other immune mediators, enhancing both innate and adaptive immune responses. TLR7/8 Agonist 4 is primarily used in preclinical research for cancer immunotherapy, vaccine adjuvants, and antiviral strategies. Its dual activation of TLR7 and TLR8 makes it effective in stimulating dendritic cells and monocytes, offering potential for robust immunomodulatory applications.
