The murine ATP-binding cassette transporter C5 (Abcc5/MRP5/cMOAT) plays a role in memory consolidation, circadian rhythm regulation and glutamatergic signalling

Abstract ATP-Binding cassette (ABC) transporters are a family of integral membrane ATPases that transport a large number of structurally unrelated compounds. The physiological role of the orphan transporter Abcc5 remains poorly understood. As previous work demonstrated that the loss of Abcc5 activit...

description Abstract ATP-Binding cassette (ABC) transporters are a family of integral membrane ATPases that transport a large number of structurally unrelated compounds. The physiological role of the orphan transporter Abcc5 remains poorly understood. As previous work demonstrated that the loss of Abcc5 activity leads to elevated levels of NAAG in the brain, the impact of Abcc5 ablation was ascertained using behavioural phenotyping, circadian rhythm analysis and electrophysiological recordings of brain slices from Abcc5 −/− mice and compared to wild-type littermates. Behavioural phenotyping of Abcc5 −/− mice shows that the loss of murine Abcc5 activity results in profound changes in pre-pulse inhibition (PPI) as well as altered memory consolidation. Circadian measures of activity showed a delay in the timing of Abcc5 −/− mice activity rhythm peak. Additionally, activity defined sleep analysis highlighted differences in sleep patterns in Abcc5 −/− mice compared to wild-type controls. Patch clamp recording from pyramidal cells in the 2/3 layer of the frontal cortex showed altered synaptic AMPA/NMDA receptor current ratios and increased frequency of spontaneous excitatory postsynaptic currents (sEPSC). This study demonstrates that the loss of functional Abcc5 transporters does have behavioural consequences in mammals and alters NMDA receptor activity. These results highlight a previously unknown role of Abcc5 in the brain.
