Description
Polyinosinic-polycytidylic acid (poly(I:C)) is a synthetic analog of double stranded RNA (dsRNA), a molecular pattern associated with viral infection. Poly(I:C) can activate the immune response through two distinct pathogen recognition receptors (PRRs). Endosomal poly(I:C) activates TLR3 while cytosolic poly(I:C) activates RIG-I/MDA-5. Triggering the TLR3 pathway induces IL-12 and type I IFNs production, and improves MHC class II expression and cross-presentation of antigen. Stimulation of MDA-5 enhances the production of type I IFNs that play a critical role in enhancing T and B cell immunity. Poly(I:C) promotes Th1 (cellular) biased immunity through its induction of IL-12 and type I IFNs. Poly(I:C) has been tested as an adjuvant in numerous animal models. Promising results have been obtained using poly(I:C) as an adjuvant in flu vaccine delivered intranasally to mice. Poly(I:C) has also been shown to enhance the efficacy of peptide-based cancer vaccines by promoting tumor specific T cell responses in mice. Immunization of mice with poly(I:C) resulted in a strong Th1 response and high levels of serum type I IFN.
Preparation of Sterile Stock Solution (1 mg/ml)
Add 10 ml of the endotoxin-free physiological water provided to the 10 mg Poly(I:C) vial. - Mix the solution by pipetting up and down. - Heat the mixture for 10 minutes at 65 - 70°C. Allow the solution to cool for 1 hour at room temperature to ensure proper annealing.
