Poly(U)
Poly (U) (Polyuridylic acid) is an RNA chain that exists in a disordered extended state at room temperature and serves as a TLR7 ligand. Poly (U) produces distinguishable blocking effects when transported through α-hemolysin nanopores. Poly (U) forms a triple helix with adenosine or adenosine monophosphate, thereby significantly promoting the nucleotide bond condensation reaction between adenosine monophosphate and adenosine, while exerting minimal effects on other nucleosides. When conjugated with cationic lipids, Poly (U) specifically stimulates plasmacytoid dendritic cells to produce type I interferons.

Biological Activity
|
TLR7 |
Poly(U) (10 μg/mL) enabled α-hemolysin nanopores to distinguish 150 nt poly(U) from poly(A) via shorter translocation durations (centered at 1.4 μs/nt and 6 μs/nt) and absence of 55% amplitude blockade shoulders[1].
Poly(U) (30 μg/mL; 24 h) does not induce IFN-α or IL-12p40 production from Flt3L-induced murine bone marrow dendritic cells alone, but does induce both cytokines when mixed with Lipofectamine 2000, with IFN-α levels reaching ~10 ng/mL and IL-12p40 levels reaching ~4 ng/mL after 24 hours[2].
