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.

Hisato Konoeda¹, Hong Yang², Chengliang Yang¹, Annette Gower¹, Chun Xu¹, Wei Zhang¹, Mingyao Liu^1,3

¹Latner Thoracic Surgery Research Laboratories, Toronto General Hospital Research Institute, University Health Network, ²Respiratory Medicine Research Laboratory, Institute of Translation Medicine, Shanghai General Hospital, Shanghai Jiaotong University, ³Institute of Medical Science, Faculty of Medicine, University of Toronto

We have previously used a gold nanoparticle peptide hybrid to intravenously deliver a synthetic peptide, protein kinase C-delta inhibitor, which reduced ischemia-reperfusion-induced acute lung injury. Here we show the detailed protocol of the drug formulation. Other intracellular peptides can be formulated similarly.
