HEK293 clones expressing TLR9
293/mTLR9 cells were obtained by stable transfection of HEK293 cells with a pUNO-TLR9 plasmid which expresses the murine TLR9 gene.
293XL/TLR9A cells were obtained by stable transfection of HEK293XL cells with a pUNO-TLR9 plasmid which expresses the human TLR9 gene.
The control cell line of 293/mTLR9 cells is 293/null.
The control cell line of 293XL/hTLR9A cells is 293XL/null cells.

Description
TLR9 is expressed in the endoplasmic reticulum of resting cells in contrast to most TLRs that are located on the plasma membrane [1]. TLR9 recognizes specific unmethylated CpG-ODN sequences, that distinguish bacterial DNA from mammalian DNA. TLR9 engages an intracellular signaling pathway that involves MyD88 leading to NF-κB translocation [2]. TLR9 recognizes different CpG motifs; the optimal sequences being GTCGTT and GACGTT for human TLR9 and murine TLR9 respectively [3]. TLR9 binds directly to CpG DNA and recognizes specifically CpG DNA that is unmethylated and single stranded [4].
