AG1529 affects capsaicin-evoked nociceptor firing. (A) Representative recordings of APs firing from DRG neurones elicited by 0.5 μM capsaicin in the absence (Untreated) and presence (AG1529) of 1 µM AG1529. APs were recorded under current clamp mode. Horizontal lines denote the duration of compound pulse. (B) Ratio of second (P2) versus first (P1) peak of APs evoked by capsaicin application in the absence (n = 12) and the presence during the P2 of 1 µM AG1529 (n = 12). (C) Representative macroscopic ionic currents evoked by a series of depolarizing 5 mV voltage steps of 10 ms, from − 50 mV to 55 mV from a holding potential of − 70 mV, in the absence (black) and the presence (blue) of 1 µM AG1529. (D) and (E) current density to voltage relationships for the inward and outward currents of panel (C), respectively. All data are expressed as mean ± SEM. Data depicted in panel (B) was analysed using an unpaired, two-tail Student’s t-test. p-value is indicated.
