Effect of red laser light on current-voltage curve of TRPV1-mediated current. TRPV1 was activated by 500 nM capsaicin. Open square were obtained before irradiation, filled circles at the end of a 2 min lasting irradiation period (637 nm, 36 mW), and open circles 2 min after the laser light was turned off. Data represent averages from 3 oocytes (SEM).
