Toll-like receptor (TLR) signaling plays an important role in the pathophysiology of many human inflammatory diseases, and regulating TLR responses by bioactive nanoparticles is anticipated to be beneficial in many inflammatory conditions. THP-1 cell-based reporter cells provide a versatile and robust screening platform for identifying novel inhibitors of TLR signaling.
