Stabilization of synaptic membranes by alpha-tocopherol against the damaging action of phospholipases. Possible mechanism of biological action of vitamin E.

Using fluorescent and ESR-spin probes, the effects of phospholipases A2, C and D on rat brain synaptosomal membranes were investigated. It was shown that the exposure of synaptosomal membranes to phospholipases A2, C and D results in their depolarization and an increase of the negative surface potential. In the case of phospholipases A2 and C, these changes… CONTINUE READING
