Specific binding of 3H-MPTP to brain homogenates is displaced predominantly by MAO-A inhibitor clorgyline in rat, and by MAO-B inhibitor deprenyl in monkey. A covalently bound metabolite is formed by MAO-B in vitro from MPTP, through a reaction almost completely inhibited by physiological concentrations of glutathione and significantly reduced by other(More)
UNLABELLED GII.4 noroviruses (NoVs) are the primary cause of epidemic viral acute gastroenteritis. One primary obstacle to successful NoV vaccination is the extensive degree of antigenic diversity among strains. The major capsid protein of GII.4 strains is evolving rapidly, resulting in the emergence of new strains with altered blockade epitopes. In(More)
A saturable, specific, high-affinity binding site for [3H]1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine was found in rat brain homogenates. The CNS regional distribution, the subcellular fractionation, and the displacement by pargyline, clorgyline, and deprenyl suggest that this binding site may correspond to monoamine oxidase.(More)
The formation of a reactive intermediate in the oxidative metabolism of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) that can covalently bind to monoamine oxidase or other cellular macromolecules has been postulated by several authors. We report here direct in vitro evidence that MPTP is converted by monoamine oxidase, predominantly type B, to a(More)
