title: MPDP+ causes a non-reversible decrease in neostriatal synaptic transmission in mouse brain slice.
abstract: MPTP causes a Parkinson's disease-like syndrome in man and certain other animals. The toxic effect occurs if monoamine oxidase B is available, indicating that an MPTP metabolite may cause the toxic effect. We tested the effect of MPDP+, the first product of MPTP oxidation, and found that it, like MPTP, caused a non-reversible decrease in synaptic transmission in the mouse brain slice preparation. As the second oxidation product, MPP+ had been shown not to cause a similar, non-reversible decrease in synaptic transmission, MPDP+ is a better candidate for the role of toxic substance.
