Effect of neurotoxic divalent cations on the activity of the intrinsic nerve ending membrane-associated sialidase of bovine brain.

abstract：:We have previously shown that 5-methyltetrahydrofolate influences neuro-secretion. The present study more precisely characterises the processes involved and considers one probable site of action. Focusing on the tyrosine-noradrenalin axis in cerebellum we showed 5-methyltetrahydrofolate causes a significant reduction ...
