Special Issue Information
Dear Colleagues,
Alzheimer’s disease (AD) and related neurodegenerative disorders are complex conditions with intricate molecular underpinnings. AD often shares pathological features with other neurodegenerative diseases, including Parkinson’s disease, Huntington’s disease, and amyotrophic lateral sclerosis. Common mechanisms include protein misfolding, aggregation, and accumulation, leading to the formation of characteristic pathological structures, such as amyloid plaques and neurofibrillary tangles. In AD, pathogenesis involves multiple interconnected mechanisms. The aggregation of amyloid-β (Aβ) peptides and the formation of neurofibrillary tangles due to hyperphosphorylated tau proteins lead to synaptic dysfunction and neuronal loss. Additionally, the dysregulation of calcium homeostasis, oxidative stress, and mitochondrial dysfunction contribute to pathogenesis. Emerging evidence suggests the involvement of inflammation, where microglial activation and astrocytic response perpetuate neuronal damage.
Moreover, dysfunctions in proteostasis, including impaired autophagy and ubiquitin-proteasome system activity, contribute to the accumulation of misfolded proteins, exacerbating neurodegeneration. Aberrant lipid metabolism and disrupted signaling cascades, such as the Wnt and insulin signaling pathways, further contribute to disease progression. Furthermore, genetic predisposition, including the role of apolipoprotein E (APOE) alleles, plays a crucial role in disease susceptibility.
Understanding these intricate molecular mechanisms holds promise for the development of targeted therapeutic interventions, such as Aβ aggregation inhibitors, tau-directed therapies, anti-inflammatory agents, and modulators of proteostasis. Integrative research efforts are needed to unravel the complex interplay between these mechanisms and to develop effective strategies for the prevention and treatment of Alzheimer's Disease and related neurodegenerative disorders.

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.
