The transient receptor potential TRPV1 is a nonselective cation channel that mediates pain sensations and is commonly activated by a wide variety of exogenous and endogenous, physical and chemical stimuli. While TRPV1 receptors are mainly found in nociceptive neurons of the peripheral nervous system, these receptors have also been described in the brain where their role is far less understood. Activation of TRPV1 reportedly regulates neurotransmitter release at several central synapses. Here we show, however, that TRPV1 suppresses excitatory transmission in rat and mouse dentate gyrus by regulating postsynaptic function in an input-specific manner. This suppression is due to a Ca2+-calcineurin and clathrin-dependent internalization of AMPA receptors. Moreover, synaptic activation of TRPV1 triggers a form of long-term depression (TRPV1-LTD) mediated by the endocannabinoid anandamide in a type 1 cannabinoid receptor-independent manner. Thus, our findings reveal a novel form of endocannabinoid- and TRPV1-mediated regulation of synaptic strength at central synapses.
