HEK293 clones expressing human TLR7 HA-tagged

293XL/hTLR7-HA cells were obtained by stable transfection of HEK293XL cells with the pUNO-hTLR7-HA plasmid which expresses the human TLR7 gene fused at the 3'end to the influenza hemaglutinine (HA).

The control cell line for 293XL/hTLR7-HA cells is 293XL/null cells.

Description

TLR7, which is abundantly expressed in lung, placenta, spleen and PBL, is phylogenetically close to TLR8 and TLR9 [1]. TLR7 recognizes small synthetic molecules such as loxoribine and R848, an imidazoquinoline compound [2]. TLR7 signaling involves the MyD88-dependent signaling cascade and induces the production of IFN-α, TNF-α and IL-12. Recently, single-stranded RNA (ssRNA) was identified as the natural ligand of TLR7 [3, 4]. ssRNA derived from HIV-1 or the influenza virus were shown to induce the production of proinflammatory cytokines in PDC. TLR7 signaling is abrogated by chloroquine indicating that it is dependent on endosomal acidification.
