Histone deacetylase (HDAC) inhibitors have been demonstrated to be beneficial in animal models of neurodegenerative diseases. Such results were mainly associated with the epigenetic modulation caused by HDACs, especially those from class I, via chromatin
That is the billion-dollar question of dementia research. Scientists have made progress in understanding what happens in the brain as the disease progresses, but they still don’t know just what kicks off these changes. Researchers believe that the vast majority of Alzheimer’s cases are due to...
Parkinson’s disease (PD) is a common neurodegenerative disorder, with idiopathic and multifactorial origin, whose mainly pathological hallmarks are the loss of dopaminergic neurons of the Substantia Nigra pars compacta (SNpc) and the brain accumulation of α-synuclein-positive Lewy bodies (De Virgilio...
(in Alzheimer’s disease), tau [25] (in numerous neurodegenerative diseases), prions [26] (in transmissible spongiform encephalopathies), alpha-synuclein [27] (in synucleinopathies, including Parkinson’s disease) and superoxide dismutase 1 [28] (in amyotrophic lateral sclerosis). Exosomes have ...

[60]. Autophagy is modulated by a wide range of proteins encoded by autophagy-related genes (ATGs) in several consecutive stages [61]. Although autophagy is a survival mechanism that helps the cell clear out damaged components [62], defective autophagy signaling is involved in the pathogenesis ...
Mixed dementia.Sometimes, a person has brain changes caused by more than one type of dementia. This is called mixed dementia. For example, you may have blocked or damaged blood vessels in your brain (vascular dementia) and brain plaques and tangles (Alzheimer’s disease) at the same time. ...
