Excerpt
TNFR1 and TNFR2 are receptors for the pro-inflammatory chemokine TNFα. Inflammation of the temporomandibular joint (TMJ) and hypersensitivity were induced in mice lacking both TNFα receptors (TNFR1/R2 -/-). After recovery from this initial priming TMJ insult lasting less than a week, a gastrointestinal (GI) chemical irritation is administered 3 weeks later. This “double-hit” initiates a recrudescence of inflammation and hypersensitivity persisting at least 18 weeks. …
