WebTLR4 is the most important member of the TLR protein family for LPS recognition and LPS-mediated inflammatory responses [66]. In addition, TLR4 requires lymphocyte antigen 96 [myeloid differentiation 2 (MD-2)] for LPS recognition by its extracellular portion [67]: without MD-2, TLR4 is not expressed on the cell surface [68]. WebJul 18, 2024 · Ba/F3 cells expressing TLR4-Flag (TLR4-F), TLR4-GFP (TLR4-G), MD2-Flag, and CD14 were pretreated with 500 μg/ml ciprofloxacin (CPFX) or levofloxacin (LVFX) for 1 h and then stimulated with 250 ng/ml of a biotinylated LPS (bLPS) or c LPS for 30 min. Cell lysates were immunoprecipitated with mouse anti-GFP antibody.

WebLPS binds to the proteins Toll-like receptor 4 (TLR4) and MD2 to activate pro-inflammatory signalling pathways. The TLR4-MD2 receptor complex is crucial for the host recognition of Gram-negative bacterial infection, and pathogens have devised many strategies to evade or manipulate TLR4-MD2 activity.
