Special Issue Information
Dear Colleagues,
In some neurodegenerative diseases, the pathology is characterised by the presence of toxic proteins that accumulate in aggregates in the brain. The aggregates and/or oligomers appear to be toxic, causing injury or cell death. However, the role of these aggregates in disease is not fully understood. These pathological proteins are implicated in neurodegenerative diseases that trigger progressive degeneration through largely unknown pathogenic mechanisms, and lack valid therapeutic approaches. In this Special Issue, the focus will be on the cellular regulation of pathological proteins in neurodegenerative diseases such as Alzheimer's disease (AD), Huntington’s disease (HD), Parkinson's disease (PD), frontotemporal dementia (FTD), dementia with Lewy bodies (DLB), amyotrophic lateral sclerosis (ALS) and prion disease (PrD).
This Special Issue will highlight the current knowledge on the regulation of pathological aggregates that form in neurodegenerative diseases.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.

Abstract: Parkinson's disease (PD) is pathologically defined as the deposition of α-synuclein (α-syn) containing Lewy bodies (LBs) and Lewy neurites (LNs). Accumulating evidence suggests that α-syn may spread within the nervous system in a prion-like manner. Extracellular vesicles (EVs) may contribute to this pathway. We and others reported ATP13A2/PARK9-deficiency results in the reduction of EVs while its overexpression leads to increased EV generation. To analyze the effect of the EV-mediated a-syn secretion in neighboring neurons, we plan to examine the alternations of Atp13a2 levels on α-syn spreading in vivo. [Methods] At three months after inoculating mouse α-syn fibrils into the striatum of three Atp13a2 null and three wild-type mice, we stained the brain sections with anti-phosphorylated α-syn antibodies, and then quantified LBs/LNs in each brain regions. We also injected the lentivirus carrying human ATP13A2 two weeks before the inoculation to examine the effect of increased levels of ATP13A2. [Results] While LBs/LNs were formed in the entire brains, no significant difference was observed in LB/LN formation between Atp13a2-deficient and wild-type mice. Interestingly, overexpression of ATP13A2 leads to decreased LB/LN formation in entire brains. [Conclusion] These results combined with our previous studies suggest that enhanced secretory pathways by increased ATP13A2 levels attenuate the spreading of α-syn in brains, suggesting a protective role of ATP13A2 in α-synucleinopathies.
