An inflammatory review of Parkinson's disease

Abstract

The symptoms of Parkinson's disease (PD) were first described nearly two centuries ago and its characteristic pathology identified nearly a century ago, yet its pathogenesis is still poorly understood. Parkinson's disease is the most prevalent neurodegenerative movement disorder and research into its pathogenesis recently accelerated following the identification of a number of causal genetic mutations. The mutant gene products all cause dysfunction of the ubiquitin-proteosome system, identifying protein modification and degradation as critical for pathogenesis. Modified non-degraded intracellular proteins accumulate in certain neuronal populations in all forms of the disease. However, neuronal degeneration is more highly selective and associates with substantial activation of microglia, the inflammatory cells of the brain. We review the current change in thinking regarding the role of microglia in the brain in the context of Parkinson's disease and animal models of the disease. Comparison of the cellular tissue changes across a number of animal models using diverse stimuli to mimic Parkinson's disease reveals a consistent pattern implicating microglia as the effector for the selective degeneration of dopaminergic neurons. While previous reviews have concentrated on the intracellular neuronal changes in Parkinson's disease, we highlight the cell to cell interactions and immune regulation critical for neuronal homeostasis and survival in Parkinson's disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
