Special Issue Information

Dear Colleagues,

In recent decades, the human life span has risen significantly, and the proportion of the aging population is constantly growing, presenting significant health and economic challenges. The risk of certain disorders, such as those related to neurodegeneration, stroke, obesity, and diabetes, is invariably increased by aging. In this Special Issue, the focus will be on molecular and cellular mechanisms of metabolic and neurodegenerative disorders, particularly diabetes, obesity, Alzheimer's diseases, stroke, vascular dementia, and Huntington’s disease. These diseases are characterized by gradual degeneration, by relatively unexplained pathogenic mechanisms, particularly neuronal circuits, and are devoid of valid therapeutic approaches. Precise awareness of the particular cell and molecular mechanisms underlying metabolic disorders and neurodegeneration is a priority for the scientific community in this scenario. This Special Issue aims to provide an overview of the main signaling pathways and molecules involved in the process of aging, highlighting their intimate connection with the onset of metabolic and neurodegenerative disorders.

This Special Issue highlights global research initiatives to examine causes, recognize biomarkers of diseases, and strategies/therapies that can alleviate the effects of diseases and reduce the social and economic effects of metabolic and neurodegenerative disorders. Original research and review papers on topics, including, but not limited to, the involvement and contribution of oxidative stress and inflammation in diabetes and obesity, new mechanisms involving neuroinflammation, oxidative stress, mitochondrial dysfunction in metabolic and neurodegenerative disorders, gut–brain interaction, and non-coding RNAs in metabolic and neurodegenerative disorders, are requested for this Special Issue. In addition, we hope to attract research aimed at identifying disease biomarkers for early diagnosis and innovative therapeutic methods or techniques to avoid the development of neurological disorders.

In short, the Special Issue welcomes high-quality studies that apply to cell and animal models.

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.

In recent times, there has been a significant increase in researchers’ interest in the functions of microRNAs and the role of these molecules in the pathogenesis of many multifactorial diseases. This is related to the diagnostic and prognostic potential of microRNA expression levels as well as the prospects of using it in personalized targeted therapy. This review of the literature analyzes existing scientific data on the involvement of microRNAs in the molecular and cellular mechanisms underlying the development of pathologies such as Alzheimer’s disease, cerebral ischemia and reperfusion injury, and dysfunction of the blood–brain barrier.

Elderly people over the age of 65 are those most likely to experience Alzheimer’s disease (AD), and aging and AD are associated with apparent metabolic alterations. Currently, there is no curative medication against AD and only several drugs have been approved by the FDA, but these drugs can only improve the symptoms of AD. Many preclinical and clinical trials have explored the impact of adjusting the whole-body and intracellular metabolism on the pathogenesis of AD. The most recent evidence suggests that mitochondria initiate an integrated stress response to environmental stress, which is beneficial for healthy aging and neuroprotection. There is also an increasing awareness of the differential risk and potential targeting strategies related to the metabolic level and microbiome. As the main participants in intracellular metabolism, mitochondrial bioenergetics, mitochondrial quality-control mechanisms, and mitochondria-linked inflammatory responses have been regarded as potential therapeutic targets for AD. This review summarizes and highlights these advances. Full article
