Special Issue Information

Dear Colleagues, 

Neurodegenerative diseases are increasingly recognized as significant social challenges across many countries. A common pathogenic feature these disorders share is the accumulation of misfolded and aggregated proteins within the brain. Since most neurodegenerative diseases are characterized as proteinopathies, a primary therapeutic strategy involves the removal of these harmful proteins from brain tissue. This book will explore the multifaceted roles of neuroproteins in the development of neurological disorders and investigate innovative therapeutic strategies targeting neuroprotein dysfunction. We invite submissions that delve into the molecular mechanisms of neuroprotein misfolding and aggregation, as well as advances in identifying and validating neuroprotein biomarkers.

We are also interested in research on RNA-based and gene-editing therapeutics, the effects of neuroprotein-related epigenetic changes, and the application of high-throughput proteomic techniques. Contributions to small molecule and protein-based treatments are welcome, alongside studies on the role of neuroproteins in immunological interactions, stroke, neuroinflammation, and traumatic brain injury. Additionally, we encourage articles that present new findings from preclinical models and clinical trials focused on neuroprotein pathways. We invite contributions that enhance our understanding of neuroproteins from both functional and pathological perspectives.

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.

Alzheimer’s disease and other neurodegenerative disorders are characterized by the accumulation of misfolded proteins, such as amyloid-beta, tau, and α-synuclein, which disrupt neuronal function and contribute to cognitive decline.

Alzheimer’s disease and other neurodegenerative disorders are characterized by the accumulation of misfolded proteins, such as amyloid-beta, tau, and α-synuclein, which disrupt neuronal function and contribute to cognitive decline. Heparan sulfate proteoglycans, particularly syndecans, play a pivotal role in the seeding, aggregation, and spreading of toxic protein aggregates through endocytic pathways. Among these, syndecan-3 is particularly critical in regulating the internalization of misfolded proteins, facilitating their propagation in a prion-like manner. This review examines the mechanisms by which syndecans, especially SDC3, contribute to the seeding and spreading of pathological protein aggregates in neurodegenerative diseases. Understanding these endocytic pathways provides valuable insights into the potential of syndecans as biomarkers and therapeutic targets for early intervention in Alzheimer’s disease and other related neurodegenerative disorders.
