Abstract

The master circadian clock located in the suprachiasmatic nuclei (SCN) is synchronised by daily exposure to light. Recently, we implicated vasoactive intestinal polypeptide (VIP) and its VPAC2 receptor in mediating these photic effects on the clock. Remarkably, targeted deletion of the VPAC2 receptor stops the mouse SCN clock, indicating that VIP signalling pathways may also be important for sustaining central clock activity. In this proposal, we will establish the role of VIP and the VPAC2 receptor in regulating the circadian effects of light and in the maintenance of circadian rhythmicity and clock output, from the level of clock gene expression through to behaviour and neuroendocrine rhythms.
