A role for inflammation has been hypothesized in the etiology and progression of Parkinson’s disease (PD). In this study, we generated, characterized, and validated the first progressive PD-related mice model (C57/B6)-intrastriatal injection of lipopolysaccharide (LPS). We showed progressive and specific dopaminergic neurodegeneration in the substantia nigra, which is accompanied by striatal dopamine depletion and progressive behavioral impairment, which was alleviated by the use of the PD drug L-Dopa. We focused on the role of NO in inflammation-promoted cell death and suggest that the expression of the inducible nitric oxide synthase plays a role in the progressive loss of dopaminergic neurons but not the initial loss induced by LPS. With this model future research can be done in gene knockout mice to study other potential mechanisms of inflammation-induced neurodegeneration. In addition, this model can be used to screen therapeutics for PD at a more clinically relevant time (i.e., after LPS injection but before manifestation of PD-related behavioral impairment), as most PD drugs are screened in animal models where inhibitors are given pre-disease induction. Thus, this novel PD-related model should be further characterized and strongly considered as a tool for future drug studies.
