293/TLR3 cells were obtained by stable transfection of HEK293 cells with a pUNO-TLR3 plasmid which expresses the human or murine TLR3 gene.

The control cell line of 293/TLR3 cells is 293/null.


293/TLR, NOD and control clones were transfected transiently with pNiFty-SEAP and stimulated with TLR and NOD ligands. After 16 hour stimulation, NF-κB-induced SEAP activity was assessed using QUANTI-Blue™, a SEAP detection medium.

Description

TLR3 recognizes double-stranded RNA (dsRNA), a molecular pattern associated with viral infection. Stimulation with poly(I:C), a synthetic analog of dsRNA, was shown to induce hyporesponsiveness in TLR3-deficient mice and considerable responsiveness in HEK293 cells expressing TLR3 [1], suggesting a specific recognition to poly(I:C) by TLR3. TLR3 signals mainly through a MyD88-independent pathway involving the TRIF/TICAM1 adapter protein that leads to the production of IFN-ß and causes dendritic cells to mature [2].
