293/hTLR3-HA cells were obtained by stable transfection of HEK293 cells with the pUNO-hTLR3-HA plasmid which expresses the human TLR3 gene fused at the 3'end to the influenza hemaglutinine (HA).

The control cell line for 293/hTLR3-HA cells is 293/null.

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].
