Loss of heat-activation with the chimeric VdTRPA1L channels. Two upper traces indicate the changes of intracellular calcium level in transfected (DsRed+) and non-transfected (DsRed-) cells with three chimeric VdTRPA1L channels in which the AR6, AR7, or ARs 6 and 7 were replaced by the corresponding ARs of HsTRPA1 (VdTRPA1L_human AR6, VdTRPA1L_human AR7, and VdTRPA1L_human ARs6/7) as well as DsRed by heat. Each line represents the intracellular calcium level in the individual cell measured by calcium imaging. The arrows show the time points when 5 μM ionomycin was added. The bottom traces show the changes of bath temperature by time (sec, second).
