Figure 7From: Comparison of P2X and TRPV1 receptors in ganglia or primary culture of trigeminal neurons and their modulation by NGF or serotonin Functional characterization of rat and mouse TG neurons. A, fraction of cells responding to α, β-meATP (independently from their response to capsaicin), to capsaicin (independently from their response to α, β-meATP) or to both agonists for rat (left panel; n = 33) and mouse (right panel; n = 50). B, persistence of the responsiveness of rat TG neurons in culture to α, β-meATP and capsaicin. a, Proportion of cells responding to α, β-meATP (black bars; n = 7, 7, 10 cell cultures for the 1st, 2nd and 3rd day, respectively) and capsaicin (grey bars; n = 7, 8 and 8 cell cultures for the 1st, 2nd and 3rd day). b, peak amplitude of currents elicited by α, β-meATP (black bars; n = 22, 11 and 31 cells for the 1st, 2nd and 3rd day, respectively) and capsaicin (grey bars; n = 16, 13 and 10 cells for the 1st, 2nd and 3rd day). Only cells responding to the agonist were included in the current analysis.Back to article page
