Polyinosinic-polycytidylic acid sodium(Poly I:C) is a synthetic dsRNA that can imitate a viral infection and elicit host immune responses by triggering specific pattern-recognition receptors (PRRs) such as toll-like receptor 3(TLR3) and retinoic acid inducible gene I(RIG-I)-like receptors, including RIG-I and melanoma differentiation-associated gene 5. Poly I:C can be used as a vaccine adjuvant for cancer immunotherapy[1-3].
poly(I:C)(20 µg in 0.2 mL of cell suspension)-electroporated AML cells potently activate DC and NK cell functions and stimulate NK-DC cross-talk in terms of tumor cell killing[4]. Activation of the TLR3 signaling pathway in cancer cells through poly I:C(100 µg/ml;72 h) makes Hela cells (human cervical cancer) dose-dependent sensitive to apoptosis induced by the protein synthesis inhibitor cycloheximide (CHX) [5].
Poly I:C(10 µg/g;p.o.) exposure induces severe intestinal injury and inflammation[6]. Pre-treatment with the viral TLR3 agonist poly(I:C) (20/200 µg) modulated innate immune responses and strengthened the resistance of neutropenic mice against E. coli K1 meningoencephalitis[7].The intratumoral synergistic combination of poly(I:C)(25 µg;i.p; six times from day9-day21)+R848 significantly prevented tumor growth and metastasis in lung cancer and fibrosarcoma immunocompetent murine models[8].
