Capsaicin 82-91 tumor necrosis factor Rattus norvegicus 0-27 18582539-2 2008 This study evaluated the hypothesis that TNFalpha increases the sensitivity of rat trigeminal neurons to capsaicin via two different mechanisms triggered by either brief or sustained exposure to the cytokine. Capsaicin 105-114 tumor necrosis factor Rattus norvegicus 41-49 18582539-3 2008 A brief (5 min) application of TNFalpha significantly sensitized capsaicin-evoked accumulation of intracellular calcium ([Ca2+]i) (226.4+/-37.7 nM vs. 167.5+/-31.3 nM) and increased capsaicin-evoked nocifensive behavior (78.3+/-9.7 vs. 30.9+/-3.6 s) as compared with vehicle pretreatment (P<0.01 for both). Capsaicin 65-74 tumor necrosis factor Rattus norvegicus 31-39 18582539-3 2008 A brief (5 min) application of TNFalpha significantly sensitized capsaicin-evoked accumulation of intracellular calcium ([Ca2+]i) (226.4+/-37.7 nM vs. 167.5+/-31.3 nM) and increased capsaicin-evoked nocifensive behavior (78.3+/-9.7 vs. 30.9+/-3.6 s) as compared with vehicle pretreatment (P<0.01 for both). Capsaicin 182-191 tumor necrosis factor Rattus norvegicus 31-39 18582539-5 2008 This long-term up-regulation of TRPV1 expression by TNFalpha correlated with enhancement in capsaicin-induced calcitonin gene-related peptide release (P<0.05). Capsaicin 92-101 tumor necrosis factor Rattus norvegicus 52-60 18582539-7 2008 In summary, our data demonstrate that TNFalpha directly enhances the sensitivity of rat trigeminal neurons to capsaicin via both rapid, non-genomic mechanisms as well as sustained genomic regulation in TRPV1 expression.
