Poly(C)

Poly(C) (Polycytidylic acid) is a pleiotropic immunostimulant that specifically binds to TLR3, RIG-I and MDA5 receptors. Poly (C) recruits adaptor proteins to activate downstream signaling pathways and induce the production of type I interferons and inflammatory cytokines. Poly (C) triggers cancer cell apoptosis via the intrinsic or extrinsic caspase pathway, thereby exerting inhibitory effects on tumor growth and metastasis. Poly (C) acts as a vaccine adjuvant to modify the tumor microenvironment, regulate the expression of endothelial adhesion molecules and induce virus-like immune responses. Poly (C) can be applied to research related to melanoma, various solid tumors, hematological malignancies and autoimmune insulin-dependent diabetes mellitus^[1][2][3].
