Polyinosinic-polycytidylic acid (poly(I:C)) is a synthetic double-<wbr></wbr>stranded RNA (dsRNA) that activates toll-<wbr></wbr>like receptor 3 and retinoic acid inducible gene 1 (RIG-<wbr></wbr>1)-<wbr></wbr>like receptors, including RIG-<wbr></wbr>1 and melanoma differentiation associated gene 5. Through these actions, poly(I:C) activates NF-<wbr></wbr>κB, induces IFN-<wbr></wbr>α, promotes dendritic cell maturation, and stimulates both innate and adaptive immunity. As poly(I:C) imitates dsRNA found in some viral genomes, it bolsters immune defense against certain viruses. Poly(I:C) also directly triggers apoptosis in some cancer cells.
