In Aging, a pair of researchers has published a perspective connecting fat (lipid) accumulation and cellular senescence in neurons to Parkinson's disease. α-syn, but not just α-syn Parkinson's disease is characterized by the loss of a specific population of neurons: the dopaminergic neurons in the substantia nigra, a part of the brain that governs movement...

A new paper elaborates on how and why microglia fail to clean up the α-synuclein protein of Parkinson's disease, gradually making the disease worse. The aggregation of Parkinson's Why We Age: Loss of ProteostasisThe loss of proteostasis is the failure of the protein-building machinery of the cell and the accumulation of misfolded proteins, which is...

In the Journal of Inflammation, researchers from Johns Hopkins University have published a detailed review of the relationship between brain inflammation and the principal diseases of dementia. A focus on genetics and environment One out of twenty Americans over 85 have Parkinson's disease [1], and seven out of twenty have Alzheimer's [2]. While genes are...

A team of researchers publishing in Nature Communications has described nanobodies that can destroy the α-synuclein aggregates that characterize Lewy bodies, which are associated with dementia and Parkinson's disease [1]. What are nanobodies? Traditional antibody therapies, while promising in some studies, are too large to enter cells in order to affect the aggregates there [2]....

A study published in Cell Reports has found α-synuclein, the fundamental protein of Parkinson's disease, to be critical in immune function. The gut-brain axis as a channel for disease Parkinson's disease, which causes damage to the portion of the brain responsible for movement, is widely known to be caused by the aggregation of α-synuclein. This...

An open-access paper published in Nature Communications sheds light on how an accumulation of α-synuclein protein in brain cells contributes to causing Parkinson’s disease. In particular, the researchers discovered how clumps of the protein damage important proteins on mitochondrial surfaces, leading to impaired energy production, swelling and bursting of the mitochondria themselves, and, ultimately, cell...
