Special Issue Information

Dear Colleagues,

It is crucial to understand the cellular and molecular mechanisms that underlie neurodevelopmental and neurological disorders to develop novel treatments. Indeed, many disorders, such as Alzheimer's disease and autism spectrum disorder, are associated with abnormalities and disruptions in crucial processes and neurobiological functions, such as neural migration, neuronal morphogenesis, and synaptogenesis. Both inherited and de novo mutations may play a significant role in the development of these disorders, with the potential to profoundly affect neurodevelopmental pathways and cellular functions in adulthood. Using advanced techniques, such as CRISPR-Cas9 genome editing and high-throughput sequencing, researchers can unravel the molecular basis contributing to the onset of neurodevelopmental and neurological disorders, thereby identifying potential therapeutic targets.

This Special Issue features original and review articles about cellular and molecular studies on neurodevelopmental and neurological disorders, utilizing current techniques, such as CRISPR/Cas9, multi-omics, etc., in any system, including animal (rodents, flies, worms, fishes, etc.) and human models, gene-modified animals, and human induced pluripotent stem cells (hiPSCs). Topics of interest include, but are not limited to, the following:

  • Autism spectrum disorder (ASD);
  • Attention deficit hyperactivity disorder (ADHD);
  • Schizophrenia;
  • Bipolar disorder;
  • Intellectual disability (ID);
  • Cognitive disorders;
  • Alzheimer's disease (AD);
  • Parkinson's disease (PD);
  • Traumatic brain injury (TBI);

Our interest is in molecular and cellular analyses of pathological features and functions of mutated proteins, including less-of-function molecules and/or gain-of-function molecules. We are also interested in articles that describe how disease-responsible genes and proteins function in normal brain development and function.

This Special Issue is supervised by Dr. Kazuhito Toyooka and assisted by Dr. Liu Xiaonan. We warmly welcome the submission of short communications, original research articles, and review articles.

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.

Air pollution is a major global health threat, responsible for over 8 million deaths in 2021, including 700,000 fatalities among children under the age of five. It is currently the second leading risk factor for mortality worldwide. Key pollutants, such as particulate matter (PM2.5, PM10), ozone, sulfur dioxide, nitrogen oxides, and carbon monoxide, have significant adverse effects on human health, contributing to respiratory and cardiovascular diseases, as well as neurodevelopmental and neurodegenerative disorders. Among these, particulate matter poses the most significant threat due to its highly complex mixture of organic and inorganic compounds with diverse sizes, compositions, and origins. Additionally, it can penetrate deeply into tissues and cross the blood–brain barrier, causing neurotoxicity which contributes to the development of neurodegenerative diseases. Although the link between air pollution and neurological disorders is well documented, the precise mechanisms and their sequence remain unclear. Beyond causing oxidative stress, inflammation, and excitotoxicity, studies suggest that air pollution induces epigenetic changes. These epigenetic alterations may affect the expression of genes involved in stress responses, neuroprotection, and synaptic plasticity. Understanding the relationship between neurological disorders and epigenetic changes induced by specific air pollutants could aid in the early detection and monitoring of central nervous system diseases.
