Accumulating evidence implicates the relationship between neuroinflammation and pathogenesis in idiopathic Parkinson's disease (iPD). The nose has recently been considered a gate way to the brain which facilitates entry of environmental neurotoxin into the brain. Our study aims to build a PD model by a natural exposure route. In this report, we establish a new endotoxin-based PD model in mice by unilateral intranasal (i.n.) instillation of the lipopolysaccharides (LPS) every other day for 5 months. These mice display a progressive hypokinesia, selective loss of dopaminergic neurons, and reduction in striatal dopamine (DA) content, as well as α-synuclein aggregation in the SN, without systemic inflammatory and immune responses. This new PD model provides a tool for studying the inflammation-mediated chronic pathogenesis and searching for therapeutic intervention in glia-neuron pathway that will slow or halt neurodegeneration in PD.
