Presynaptic inhibition is one of the major control mechanisms in the CNS. Previously we reported that adenosine A1 receptors mediate presynaptic inhibition at the retinotectal synapse of goldfish. Here we extend these findings to metabotropic glutamate receptors (mGluRs) and report that presynaptic inhibition produced by both A1 adenosine receptors and(More)
This study aims to identify the inhibitory role of the spinal glucagon like peptide-1 receptor (GLP-1R) signaling in pain hypersensitivity and its mechanism of action in rats and mice. First, GLP-1Rs were identified to be specifically expressed on microglial cells in the spinal dorsal horn, and profoundly upregulated after peripheral nerve injury. In(More)
Presynaptic adenosine receptors inhibit transmitter release at many synapses and are known to exist on retinotectal terminals. In this paper we show that adenosine decreases retinotectal field potentials by approximately 30% and investigate the mechanism. First, as judged by the effects of specific calcium channel blockers, retinotectal transmission was(More)
Nonimmunosuppressant immunophilin ligands have been found previously to stimulate neurite growth in culture and to promote regeneration of peripheral and central nerve fibers in vivo. To further characterize the effectiveness of these ligands, we have investigated the effect of the immunophilin ligand GPI-1046 in 6-hydroxydopamine (6-OHDA)-lesioned rats. In(More)
