Time-of-day-dependent expression of purinergic receptors in mouse suprachiasmatic nucleus.

ABSTRACT: Purinergic P2X and P2Y receptors are involved in mediating intercellular signalling via purines such as adenosine triphosphate (ATP). P2X and P2Y receptors have been implicated in numerous body functions including learning, memory and sleep. All of these body functions show time-of-day-dependent variations controlled by the master circadian oscillator located in the suprachiasmatic nucleus (SCN). Evidence exists for a role of purinergic signalling in intercellular coupling within SCN. However, few studies have been performed on the expression of purinergic receptors in SCN. Therefore, we analyse the expression of seven P2X (P2X1-7) and eight P2Y (P2Y1-2, 4, 6, 11-14) receptors in mouse SCN and address their time-of-day-dependent variation by using immunohistochemistry and real-time polymer
