Special Issue Information
Dear Colleagues,
Neurodegenerative diseases, including Alzheimer’s disease (AD), Parkinson’s disease, Huntington’s disease, and amyotrophic lateral sclerosis, are characterized by the progressive loss of neurons in specific brain regions. A hallmark of these conditions is the accumulation of misfolded and aggregated proteins, which disrupt cellular functions and significantly contribute to neuronal death. To counteract this, cells deploy sophisticated quality control systems such as molecular chaperones, the ubiquitin–proteasome system, autophagy, and the unfolded protein response. These mechanisms are crucial for ensuring proper protein folding and function, thereby preventing the harmful accumulation of misfolded proteins. The degradation of these aggregates through cell-mediated, enzymatic, and other clearance pathways is equally vital in the context of neurodegenerative diseases. For example, in AD, the enzymes responsible for the production of aggregation-prone amyloid β peptides, as well as their clearance mechanisms, are closely linked to the disease’s onset and progression. Understanding the intricate relationship between protein aggregation, the protein quality control system, clearance, and neurodegeneration is essential for developing new therapeutic strategies.
This Special Issue is dedicated to exploring the protein quality control system in the context of neurodegenerative diseases. Our aim is to elucidate the underlying mechanisms and highlight potential therapeutic strategies that could prove instrumental in managing these debilitating conditions.

Manuscript Submission Information
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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
