Abstract
The effects of soybean transphosphatidylated phosphatidylserine(SB−tPS)on cholinergic synaptic functions were investigated using cerebral cortical synaptosomes from mice.Treatment of the synaptosomes with SB−tPS increased high K+−induced acetylcholine(ACh)release in a bell−shaped, dose−dependent manner without affecting ACh synthesis.SB−tPS(10 and 50μM)also enhanced synaptosomal synthesis of sn−glycero−3−phosphocholine, but did not affect phosphorylcholine synthesis.In contrast, the choline synthesis was significantly reduced as SB−tPS concentration increased.The present result that SB−tPS modified the cholinergic pathway can partly explain its nootropic functions.
