The roles of TRPV1 receptors in nervous system with a special emphasis on sleep and memory.

Transient receptor vanillin 1 (TRPV1) is widely expressed in the neural axis and surrounding tissues, and is easily activated by harmful stimuli such as pain and inflammatory responses. Previous studies have shown that activated TRPV1 channels regulate all levels of nervous system activity by improving calcium influx and modulating nervous system excitability. Recent studies have suggested that TRPV1 activation in the peripheral nervous system may induce sleep disorders, while activation in the central nervous system may ameliorate sleep disorders and assist memory consolidation processes. Here, we summarize the risk factors for inducing sleep disorders, the alteration of these risk factors by TRPV1 receptor activation, and the driving effect of TRPV1 receptor activity on memory consolidation.
