TLR7 and/or TLR8 activation with ssRNA
TLR8 Agonist - RNA homopolymer - complexed with LyoVec™
ssPolyU/LyoVec™ is a lyophilized and complexed preparation of single-stranded poly-uridine (ssPolyU), able to activate the Toll-like receptors TLR7 and/or TLR8.
Single-stranded RNA (ssRNA) has been identified as the natural ligand of TLR7 and TLR8 [1]. ssRNA derived from HIV-1 or the influenza virus were shown to induce the production of proinflammatory cytokines in pDC [2,3]. This induction was reproduced using polyU or GU-rich oligoribonucleotides (ORNs).
Description
InvivoGen's ssPolyU is complexed with the cationic lipid LyoVec™ to protect it from degradation and facilitate its uptake. ssPolyU/LyoVec™ is a specific agonist of human TLR8 as verified by using our HEK-Blue™ reporter cell lines (see figure). Moreover, it activates mouse TLR7 [data not shown].
InvivoGen also offers a non-complexed version ssPolyU Naked.
Key features of ssPolyU/LyoVec™
- Specific activator of human TLR8
- No activation of human TLR7
- Non-complexed ssPolyU Naked is available
- Complexed with LyoVec™
- Each lot of ssPolyU/LyoVec™ is functionally tested
