A novel TLR4-mediated signaling pathway leading to IL-6 responses in human bladder epithelial cells.
The vigorous cytokine response of immune cells to Gram-negative bacteria is primarily mediated by a recognition 5 molecule, Toll-like receptor 4 (TLR4), which recognizes lipopolysaccharide (LPS) and initiates a series of intracellular NF-kappaB-associated signaling events.Recently, bladder epithelial cells (BECs) were reported to express TLR4 and t
