The effect of growth factor treatment on AEA- and ACEA-evoked CGRP release. TG neurons were grown in the presence of the indicated concentrations of NGF (panel A), GDNF (panel B) or BDNF (panel C) for five days and then exposed to 100 nM CAP, 30 μM AEA or 30 μM ACEA for 10 min, and the released CGRP was quantified (n = 12). Panel D, TG neurons were grown in the absence of growth factors or in the presence of 100 ng/ml NGF or GDNF for 5 days and exposed to the indicated concentrations of AEA (molar, log units) to assess CGRP release (### p < 0.001; GDNF and NGF vs. no growth factor; two-way ANOVA, Bonferroni post-test, n = 6).
