Short-term depression and long-term enhancement of ACh-gated channel currents induced by linoleic and linolenic acid.

Abstract excerpt

The effects of cis-unsaturated free fatty acids such as linoleic and linolenic acid on ACh-evoked currents were examined using normal and mutant nicotinic acetylcholine (ACh) receptors lacking protein kinase C (PKC) phosphorylation sites on the alpha and delta subunits expressed in Xenopus oocytes. These free fatty acids reduced ACh-gated channel currents during treatment and to a greater extent in Ca2+-free...
