Topic: Alpha Synuclein

Alpha synuclein and Lrrk2 are key players in Parkinson's disease and related disorders, but their normal role has been confusing and controversial. Data from acute gene-editing based knockdown, followed by functional assays, will be presented.

Parkinson's disease (PD) is the second most present neurodegenerative disease in the world after Alzheimer's. It is due to the progressive and irreversible loss of dopaminergic neurons of the substantia nigra Pars Compacta. Alpha synuclein deposits and the appearance of Lewi bodies are systematically associated with it. PD is characterized by four cardinal motor symptoms: bradykinesia / akinesia, rigidity, postural instability and tremors at rest. These symptoms appear when 80% of the dopaminergic endings disappear in the striatum. According to Braak's theory, non-motor symptoms appear much ea
