Mechanism of action

Poly IC (polyinosinic-polycytidylic acid) mimics viral double-stranded RNA and binds to TLR3 on immune cells, triggering interferon production and activation of natural killer cells and cytotoxic T lymphocytes. This enhances antiviral and antitumor immune responses through pattern recognition receptor activation.
