Subunit-dependent modulation of kainate receptors by muscarinic acetylcholine receptors.
Interactions between cholinergic and glutamatergic neurotransmitter systems influence synaptic transmission and plasticity. While previous studies have examined cross-talk between acetylcholine (ACh) and NMDA or AMPA receptors, little is known about the effect of ACh on kainate receptors (KARs). We show that stimulation of m1 or m3 muscarinic ACh receptors (mAChRs) for 2min potentiates recombin...
متن کاملAllosteric Modulation of Muscarinic Acetylcholine Receptors
An allosteric modulator is a ligand that binds to an allosteric site on the receptor and changes receptor conformation to produce increase (positive cooperativity) or decrease (negative cooperativity) in the binding or action of an orthosteric agonist (e.g., acetylcholine). Since the identification of gallamine as the first allosteric modulator of muscarinic receptors in 1976, this unique mode ...

متن کاملAlcohol Modulation of Neuronal Nicotinic Acetylcholine Receptors Is Subunit Dependent
Background: We have previously shown that n-alcohols exert a dual action on the 4 2-type neuronal nicotinic acetylcholine (ACh) receptors (AChRs), with shorter-chain alcohols potentiating and longerchain alcohols inhibiting ACh-induced currents. Ethanol potentiates the current in 4 2 receptors, yet it has little or no effect on the 3 2 receptors. Because the 4 AChRs are present predominantly in...
متن کاملSubunit-dependent modulation of kainate receptors by extracellular protons and polyamines.
Synaptic activity causes significant fluctuations in proton concentrations in the brain. Changes in pH can affect neuronal excitability by acting on ligand-gated channels, including those gated by glutamate. We show here a subunit-dependent regulation of native and recombinant kainate receptors by physiologically relevant proton concentrations. The effect of protons on kainate receptors is volt...
