Toll-like receptor 4 (TLR4) expressed on spinal microglia and astrocytes has been suggested to play an important role in the regulation of pain signalling. The purpose of the present work was to examine the links between TLR4, glial activation and spinal release of prostaglandin E(2) (PGE(2)) and tumour necrosis factor (TNF), and the role these factors play in TLR4-induced tactile allodynia.
