1 The NK1 receptor antagonist SR140333 inhibits capsaicin-induced ERK phosphorylation in sensory neurons. Capsaicin Eph receptor B1 Rattus norvegicus
2 Capsaicin evoked a threefold increase in phospho-ERK in the sciatic nerve and a two- to threefold increase in the DRG at 3 h and 6 h after the treatment. Capsaicin Eph receptor B1 Rattus norvegicus
3 SR140333 markedly attenuated the capsaicin-induced increase in phosphorylated ERK. Capsaicin Eph receptor B1 Rattus norvegicus
4 Based on the present results and previous findings it can be postulated that the capsaicin-induced ERK phosphorylation in sensory neurons is not a direct effect by capsaicin, but that rather substance P release from the stimulated sensory neurons with an NK1-mediated nerve growth factor (NGF) production is involved. Capsaicin Eph receptor B1 Rattus norvegicus
