Abstract
We characterized the role of adenosine receptor (AR) subtypes in the modulation of glutamatergic neurotransmission by the chemokine fractalkine (CX3CL1) in mouse hippocampal CA1 neurons. CX(3)CL1 causes a reversible depression of excitatory postsynaptic current (EPSC), which is abolished by the A(3)R antagonist MRS1523, but not by A(1)R (DPCPX) or A(2A)R (SCH58261) antagonists. Consistently, CX3CL1-induced EPSC depression is absent in slices from A(3)R(-/-) but not A(1)R(-/-) or A(2A)R(-/-) mice. Further, A(3)R stimulation causes similar EPSC depression. In cultured neurons, CX3CL1-induced depression of AMPA current shows A(1)R-A(3)R pharmacology. We conclude that glutamatergic depression induced by released adenosine requires the stimulation of different ARs. (c) 2010 Elsevier B.V. All rights reserved.Entities:
