WebDec 31, 2024 · TLR3 specifically recognizes dsRNA derived from viruses, as well as polyinosinic–polycytidylic acid [poly(I:C)], a synthetic agonist that mimics viral dsRNA 2,3. WebNov 1, 2024 · Toll-like receptor 3 (TLR3) activation promotes IFN-β production, which induces apoptosis and impairs proliferation in some cancer cells. Herein, we tested whether the TLR3 agonist polyinosinic: polycytidylic acid (poly I:C) can improve chemotherapeutic efficacy in paclitaxel (PTX) resistant cell lines.
