Inhibitory effects of arachidonic acid on nicotinic transmission in bullfrog sympathetic neurons.
Inhibitory effects of arachidonic acid on nicotinic transmission in bullfrog sympathetic neurons. J. Neurophysiol. 78: 2396-2401, 1997. Arachidonic acid (AA, 0.2-40 mu M) reversibly reduced the amplitude of the fast excitatory postsynaptic potentials and the underlying currents (fast EPSCs) of bullfrog sympathetic neurons evoked by preganglionic nerve stimulation in a Ca2+-deficient solution. A...
متن کاملSlow synaptic transmission in frog sympathetic ganglia.
Bullfrog ganglia contain two classes of neurone, B and C cells, which receive different inputs and exhibit different slow synaptic potentials. B cells, to which most effort has been directed, possess slow and late slow EPSPs. The sEPSP reflects a muscarinic action of acetylcholine released from boutons on B cells, whereas the late sEPSP is caused by a peptide (similar to teleost LHRH) released ...
متن کاملMechanism of long-term potentiation of transmitter release induced by adrenaline in bullfrog sympathetic ganglia
A mechanism of the long-term potentiation of transmitter release induced by adrenaline (ALTP) was studied by recording intracellularly the fast excitatory postsynaptic potentials (fast EPSPs). The ALTP was produced during the blockade of K+ channels at the presynaptic terminals by tetraethylammonium (TEA). The synaptic delay, possibly reflecting a relative change in the duration of an action po...
متن کاملDifferential modulation of nicotinic acetylcholine receptor subtypes and synaptic transmission in chick sympathetic ganglia by PGE(2).
The diversity of neuronal nicotinic acetylcholine receptors (nAChRs) is likely an important factor in the modulation of synaptic transmission by acetylcholine and nicotine. We have tested whether postsynaptic nAChRs are modulated in a subtype-specific manner by prostaglandin E(2) (PGE(2)), a regulator of neuronal excitability in both the central and peripheral nervous systems, and examined the ...
