Nurr1 in Parkinson's disease and related disorders.
Chu Y, Le W, Kompoliti K, Jankovic J, Mufson EJ, Kordower JH
This study shows that Nurr1 protein levels drop in specific brain neurons when they contain pathological clumps associated with Parkinson's, Alzheimer's, and PSP. The reduction of Nurr1 correlates with the loss of dopamine-producing markers, suggesting it is a consequence of neurodegeneration rather than a primary cause.
- Nurr1 levels decrease in substantia nigra neurons containing alpha-synuclein clumps in Parkinson's disease.

Castelo-Branco G, Sousa KM, Bryja V, Pinto L, Wagner J, Arenas E
Ventral midbrain glial cells secrete Wnt-5a to help neural precursors develop into dopamine-producing neurons. This process relies on region-specific transcription factors and is partially blocked when Wnt-5a signaling is inhibited.
- Midbrain glia, not cortical glia, produce high levels of Wnt-5a.
