The ability to sense and respond to thermal stimuli at varied environmental temperatures is essential for survival in seasonal areas. In this study, we show that mice respond similarly to ramping changes in temperature from a wide range of baseline temperatures. Further investigation suggests that this ability to adapt to different ambient environments is based on rapid adjustments made to a dynamic temperature setpoint. The adjustment of this setpoint requires TRPM8 but not TRPA1 and is regulated by phospholipase C (PLC) activity. Overall, our findings suggest that temperature response thresholds in mice are dynamic, and that this ability to adapt to environmental temperature seems to mirror the in vitro findings that PLC-mediated hydrolysis of phosphoinositol 4,5-bisphosphate modulates TRPM8 activity and thereby regulates the response thresholds to cold stimuli.
