Special Issue Information

Dear Colleagues,

The study of epigenetics has emerged as a critical frontier in our understanding of the intricate relationship between genes and the environment in the development and progression of mental disorders. Epigenetic processes, which regulate gene expression without altering the underlying DNA sequence, have been increasingly recognized as a key mechanism by which environmental factors can influence the risk and manifestation of conditions such as schizophrenia, bipolar disorder, major depressive disorder, and eating disorders.

Mounting evidence suggests that epigenetic modifications, driven by factors like nutrition, stress, and early-life experiences, can lead to long-lasting changes in brain function and behavior, ultimately contributing to the onset and trajectory of mental disorders. Whereas genetic studies have identified numerous risk loci associated with these conditions, the complex interplay between genes and environment remains incompletely understood. Studies on the epigenetics of mental disorders have the potential to elucidate novel pathways and targets for prevention and intervention, as epigenetic changes may be reversible or amenable to pharmacological modulation.

Potential topics include, but are not limited to:

  • Epigenetic or epigenomic studies in patients with mental disorders;
  • Epigenetic or epigenomic studies on animal or cellular models of mental disorders;
  • Studies on the gene–environment interactions in mental 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.

The intrauterine environment is increasingly recognised as a critical period for the emergence of mental health vulnerabilities. This review explores how adverse maternal exposures, such as psychological stress, infection, malnutrition, and environmental toxins, can disrupt foetal neurodevelopment via epigenetic mechanisms, contributing to the risk of psychiatric and neurodevelopmental disorders. Focusing primarily on human studies, we synthesise evidence on DNA methylation, histone modifications, and non-coding RNAs as key pathways through which the intrauterine environment influences gene regulation in the developing brain. We examine how timing of exposure, foetal sex, and gene–environment interactions modulate these effects, with particular attention to disorders such as schizophrenia, autism spectrum disorder, depression, and anxiety. The placenta emerges as a central mediator, both reflecting and shaping epigenetic changes in response to maternal signals. We also discuss the reversibility of epigenetic marks and highlight emerging interventions, including nutritional supplementation and maternal mental health support, that may buffer or reverse prenatal epigenetic programming. Methodological challenges are addressed, including tissue specificity and causal inference, and future directions are proposed toward integrating epigenetic biomarkers into early risk assessment and precision mental health and psychiatry. This review emphasises the importance of the prenatal period as a window of vulnerability and opportunity for shaping lifelong mental health. Full article
