1 | The capacity of the proinflammatory cytokines, tumor necrosis factor alpha (TNF alpha) and interleukin 1 beta (IL-1 beta), to modulate the sensitivity of isolated sensory neurons grown in culture to the excitatory chemical agent capsaicin was examined. | Capsaicin | tumor necrosis factor | Rattus norvegicus |
2 | A 24 hr pretreatment of the neuronal cultures with TNF alpha (10 or 50 ng/ml), but not IL-1 beta (10 or 50 ng/ml), produced a concentration-dependent increase in the number of cobalt-labeled neurons after exposure to 100 nM capsaicin. | Capsaicin | tumor necrosis factor | Rattus norvegicus |
3 | Similarly, pretreatment with TNF alpha (10 ng/ml for 4, 12, and 24 hr) produced a greater than twofold increase in the average peak amplitude of the inward current evoked by 100 nM capsaicin. | Capsaicin | tumor necrosis factor | Rattus norvegicus |
4 | These results indicate that TNF alpha can enhance the sensitivity of sensory neurons to the excitation produced by capsaicin and that this enhancement likely is mediated by the neuronal production of prostaglandins. | Capsaicin | tumor necrosis factor | Rattus norvegicus |
