A 6-Hydroxydopamine In Vivo Model of Parkinsons Disease

互联网

532
Animal models of Parkinson’s disease are essential to explore pathophysiological hypotheses and to test new treatment options, including neurotrophic factors. Catecholaminergic neurotoxins used to generate such models are 6-hydroxydopamine and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. These neurotoxins predominantly kill dopaminergic neurons through oxidative damage and mitochondrial failure, although 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine fails to induce a significant dopaminergic neurodegeneration in rats. The present chapter describes a protocol for the 6-hydroxydopamine rat model based on stereotaxic injection performed only unilaterally, which mimics an early-to-mid stage of the disease.
