RIBOXXOL is a synthetic double stranded RNA (dsRNA). It has a length of 50 bp. It is composed of cytosines, inosines and guanosines.

Double stranded RNA is a potent activator of innate immunity. In the context of innate immunity, dsRNA is a pathogen associated molecular pattern (PAMP) that activates innate immune response through pathogen recognition receptors (PRR). The PRR of RIBOXXOL is Toll-like-receptor 3 (TLR3).
            
TLR3 is present in the endosome of myeloid dendritic cells (DCs) and Natural Killer cells [1]. Signaling of TLR3 is triggered by dsRNA with a length of more than 45 bp [2,3].
Triggering the TLR3-pathway through dsRNA induces IL-1ß, 1L-12 and type I IFNs production, improves cross-presentation of antigens and MHC class I expression.
RIBOXXOL promotes Th1 (cellular) immune response, production of IFN-y by NK cells, and  activates monocytes.

In animal models, RIBOXXOL enhances the adaptive immune response of peptide-based vaccines (in applications such as cancer, hepatitis), induces tumor specific T cell responses and high levels of cytokines (Th1). Moreover, RIBOXXOL displays a resistance to serum and body fluids. It is therefore ideal for experimental set-up in cell culture supplemented with Fetal Calf Serum (FCS) and in small animal models.
