Fig. three Schematic representation of cellular and molecular functions linked to METH-induced DA neurotoxicity inside the striatum. METH enters dopaminergic neurons through DAT and passive diffusion. Within just these neurons, METH enters synaptic vesicles by means of VMAT-two and results in DA release in the cytoplasm by disturbing pH harmony. Within the cytoplasm, DA auto-oxidizes to type harmful DA quinones accompanied by era of superoxide radicals and hydrogen peroxides. Subsequent development of hydroxyl radicals via interactions of superoxides and hydrogen peroxide with transition metals contributes to oxidative anxiety, mitochondrial dysfunctions, and peroxidative harm to pre-synaptic membranes. The involvement of endogenous DA in METH toxicity is supported by conclusions the TH inhibitor, α-methyl-p-tyrosine, which blocks DA synthesis, affords safety towards METH toxicity.
