By tweaking genes used by placental and cancerous cells to evade immune detection, scientists have created non-immunogenic neuronal grafts that may help Parkinson’s patients [1]. Sneakiness needed In recent years, scientists have learned to produce cells via cellular reprogramming, a process in which differentiated cells are driven back to a pluripotent, stem-like state. These are...

Experimenting on rodents, researchers have found a pathway through which exercise could fight Parkinson's disease and a molecule that might recapitulate this effect. Fighting inflammation is crucial in Parkinson's Parkinson's disease is characterized by Lewy bodies and the loss of dopaminergic neurons [1]. Recent work has found that this degeneration is related to neuroinflammation: the...

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...

Scientists have tested a novel method of providing cells with healthy mitochondria to fight Parkinson’s disease [1]. Replacing damaged mitochondria Parkinson’s disease is the second-most prevalent neurodegenerative disorder, and it affects 10 million people worldwide. The disease is age-related, as its prevalence rises rapidly in people older than 65, although some people are diagnosed much...

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...
