THP1-Dual™ KO-MyD Cells

MyD88 knockout dual reporter monocytes

THP1-Dual KO-MyD cells were specifically designed to monitor MyD88-mediated signaling.

They were generated from THP1-Dualcells by stable knockout of the MyD88 gene. They stably express two inducible secreted reporter genes: Lucia luciferase and SEAP (secreted embryonic alkaline phosphatase).
The Lucia luciferase reporter gene is under the control of an ISG54 (interferon-stimulated gene) minimal promoter in conjunction with five IFN-stimulated response elements.
The SEAP gene is driven by an IFN-β minimal promoter fused to five copies of the NF-κB consensus transcriptional response element and three copies of the c-Rel binding site.
As a result, they allow the simultaneous study of the IFN regulatory factor (IRF) pathway, by assessing the activity of Lucia luciferase and the NF-κB pathway, by monitoring the activity of SEAP. Both reporter proteins are readily measurable in the cell culture supernatant when using QUANTI‑Luc, a Lucia™ detection reagent and QUANTI-Blue, a SEAP detection reagent.

THP1-Dual™ KO‑MyD cells are unable to respond to the activation of receptors whose signaling is dependent on MyD88, such as TLR2, TLR4, TLR5, TLR8 and IL-1Rs.
These cells remain responsive to MyD88‑independent receptors, such as NOD1 and TNFR. Activation of the IRF pathway is unaffected by the knockout of the MyD88 gene.

THP1-Dual™ KO-MyD cells are resistant to the selectable markers blasticidin and Zeocin.

THP1 reporter cells are a family of cells derived from the human monocytic THP-1 cell line, which naturally expresses many pathogen recognition receptors (PRRs), including Toll-like receptors.

They respond to ligands for certain TLRs; namely, TLR2, TLR1/2, TLR2/6, TLR4, TLR5 and TLR8. These cells can also be used to study DNA sensing pathways, as they are highly responsive to PRR agonists that trigger interferon (IFN) signaling pathways.

THP1‑Dual™ cells feature two reporter genes that enable the simultaneous study of the NF-κB and IFN signaling pathways.
