HEK293 clones expressing TLR8
293XL/TLR8 cells were obtained by stable transfection of HEK293XL cells with a pUNO-TLR8 plasmid which expresses the human TLR8 gene.
The control cell line of 293XL/TLR8 cells is 293XL/null cells.

Description
TLR8 was identified together with TLR7 and TLR9 and is expressed more abundantly in PBL and lung [1]. Human TLR8 and TLR7 were reported to independently confer responsiveness to R848, an imidazoquinolone with antiviral activity. R848 induces the activation of NF-κB in HEK293 cells transfected with human TLR8 but not in HEK293 cells expressing murine TLR8, suggesting a species specificity [2]. Recently, single-stranded RNA (ssRNA) was identified as the natural ligand of human TLR83. GU-rich ssRNA oligonucleotides derived from HIV-1 were shown to activate DC and macrophages. TLR8 recognizes ssRNA in the endosomal compartment and leads to the secretion of cytokines [3].
