CGRP release by NMDA, glutamate, and capsaicin in TG cells: (A) Histogram showing CGRP concentration in control (ctrl) and after application of glutamate (Glu, 1 mM with 10 µM glycine) for 15 min to TG cells obtained from P10-P12 rats. Notice that CGRP level was not changed by glutamate application; (B) CGRP concentration in control and after exposure to NMDA (30 µM with 10 µM glycine) for 15 min. Like with glutamate, after application of NMDA, the level of CGRP remained at a basal level; (C) CGRP concentration after exposure to capsaicin (1 µM), positive control. Notice large increase in CGRP release. Mean ± SEM. * p < 0.05.
