Special Issue Information

Dear Colleagues,

In recent years, the relationship between abnormal protein accumulation in neurons and aging has garnerd significant attention, particularly in the context of neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease. Understanding the changes in the brain and the aging process of neural tissues is a crucial step towards preventing and treating neurodegenerative disease, and Alzheimer’s disease (AD) and Parkinson’s disease (PD) constitute representative examples. Notably, the FDA’s approval of antibody therapy targeting amyloid beta in AD has sparked considerable interest. This milestone holds great significance in AD, a disease characterized by the presence of two types of abnormal protein accumulation: tau and amyloid. While antibody therapies for PD, primarily targeting alpha-synuclein, were anticipated, unfortunately, they were all prematurely halted during their clinical trials.

This Special Issue aims to focus on the association between aging and neurodegenerative disease while highlighting neuropathological features and presenting the latest research findings in this field. By comprehending the changes in the brain during aging, we will delve into the neuropathological characteristics of major neurodegenerative disease, such as AD, PD, PSP, and CBD. Moreover, we will provide an overview of the recent advancements in research related to abnormal proteins implicated in neurodegenerative diseases, including tau, amyloid beta, and alpha-synuclein. The potential for early diagnosis and treatment strategies based on neuropathological features will also be addressed. Through this refined collection of articles, we aim to shed light on the intricate connection between aging and neurodegenerative diseases, offering valuable findings for researchers, clinicians, and healthcare professionals, and fostering new perspectives in the understanding and management of 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.

Parkinson’s disease (PD) is characterized by a long prodromal period, during which patients often have sleep disturbances. The histaminergic system and circadian rhythms play an important role in the regulation of the sleep–wake cycle. Changes in the functioning of these systems may be involved in the pathogenesis of early stages of PD and may be age-dependent. Here, we have analyzed changes in the expression of genes associated with the regulation of the sleep–wake cycle (Hnmt, Hrh1, Hrh3, Per1, Per2, and Chrm3) in the substantia nigra (SN) and striatum of normal male mice of different ages, as well as in young and adult male mice with an MPTP-induced model of the early symptomatic stage (ESS) of PD. Age-dependent expression analysis in normal mouse brain tissue revealed changes in Hrh3, Per1, Per2, and Chrm3 genes in adult mice relative to young mice. When gene expression was examined in mice with the MPTP-induced model of the ESS of PD, changes in the expression of all studied genes were found only in the SN of adult mice with the ESS model of PD. These data suggest that age is a significant factor influencing changes in the expression of genes associated with sleep–wake cycle regulation in the development of PD. Full article

Abstract
Elderly human brains are vulnerable to multiple proteinopathies, although each protein has a different transmission pathway. Tau-immunoreactive astrocytes are well-known in elderly brains. In contrast, astrocytic plaques, a hallmark in corticobasal degeneration (CBD), rarely occur in aging and neurodegenerative disease other than CBD. [...] Read more.
Elderly human brains are vulnerable to multiple proteinopathies, although each protein has a different transmission pathway. Tau-immunoreactive astrocytes are well-known in elderly brains. In contrast, astrocytic plaques, a hallmark in corticobasal degeneration (CBD), rarely occur in aging and neurodegenerative disease other than CBD. To elucidate the clinicopathological correlation of aging-related pathology in CBD, we examined 21 pathologically proven CBD cases in our institute (12 males and 9 females, with a mean age of death 70.6 years). All CBD cases showed grains and neurofibrillary tangles (NFTs). Fifteen cases (71.4%) showed beta-amyloid deposition such as senile plaques or cerebral amyloid angiopathy. Three cases (14.3%) had Lewy body pathology. One case was classified as amygdala-predominant Lewy body disease, although no cases met the pathological criteria for Alzheimer’s disease. Five cases (23.8%) displayed Limbic-predominant and age-related TDP-43 encephalopathy (LATE). NFTs, grains, and TDP-43-positive neuronal inclusions were widely distributed throughout the limbic system of CBD patients, but their densities were low. CBD might a have similar cell vulnerability and transmission pathway to that of multiple proteinopathy in aging brains. Full article
