摘要：

Previous studies demonstrate that intrastriatal injections of fibrillar alpha-synuclein (alpha-syn) into mice induce Parkinson's disease (PD)-like Lewy body (LB) pathology formed by aggregated alpha-syn in anatomically interconnected regions and significant nigrostriatal degeneration. The aim of the current study was to evaluate whether exogenous mouse alpha-syn pre-formed fibrils (PFF) injected into the striatum of rats would result in accumulation of LB-like intracellular inclusions and nigrostriatal degeneration. Sprague-Dawley rats received unilateral intrastriatal injections of either non-fibrillized recombinant alpha-syn or PFF mouse alpha-syn in 1- or 2- sites and were euthanized at 30, 60 or 180 days post-injection (pi). Both non-fibrillized recombinant alpha-syn and PFF alpha-syn injections resulted in phosphotylated alpha-syn intraneuronal accumulations (i.e., diffuse Lewy neurite (LN)- and LB-like inclusions) with significantly greater accumulations following PFF injection. LB-like inclusions were observed in several areas that innervate the striatum, most prominently the frontal and insular cortices, the amygdala, and the substantia nigra pars compacta (SNpc). alpha-Syn accumulations co-localized with ubiguitin, p62, and were thioflavin-S-positive and proteinase-k resistant, suggesting that PFF-induced pathology exhibits properties similar to human LBs. Although alpha-syn inclusions within the SNpc remained ipsilateral to striatal injection, we observed bilateral reductions in nigral dopamine neurons at the 180-daytime-point in both the 1- and 2-site PFF injection paradigms. PFF injected rats exhibited bilateral reductions in striatal dopaminergic innervation at 60 and 180 days and bilateral decreases in homovanillic acid; however, dopamine reduction was observed only in the striatum ipsilateral to PFF injection. Although the level of dopamine asymmetry in PFF injected rats at 180 days was insufficient to elicit motor deficits in amphetamine-induced rotations or forelimb use in the cylinder task, significant disruption of ultrasonic vocalizations was observed. Taken together, our findings demonstrate that alpha-syn PFF are sufficient to seed the pathological conversion and propagation of endogenous alpha-syn to induce a progressive, neurodegenerative model of alpha-synucleinopathy in rats.
