Special Issue Information

Dear Colleagues,

The intricate crosstalk between epigenetic regulation and immune function has emerged as a pivotal area of investigation in both basic and translational research. Epigenetic mechanisms—including DNA methylation, histone modifications, chromatin remodeling, and non-coding RNAs—play fundamental roles in governing immune cell development, differentiation, activation, and functional plasticity. In turn, immune signaling pathways can reshape the epigenetic landscape, particularly in response to inflammation, infection, cancer, and autoimmune conditions.

This Special Issue aims to explore the mechanistic and functional intersections between epigenetics and immunology, with a focus on how these interactions influence immune regulation in health and disease. We welcome a broad range of contributions, including original research articles, reviews, and perspectives, that investigate how epigenetic mechanisms shape innate and adaptive immune responses, memory formation, immune tolerance, and dysfunction.

Topics of interest include, but are not limited to, the following:

  • Immune surveillance and recognition of epigenetic marks;
  • Epigenetic regulation of immune cell development and function;
  • Chromatin dynamics in innate and adaptive immunity;
  • Epigenetic plasticity in response to inflammation and environmental cues;
  • Mechanisms of tumor immune evasion driven by epigenetic alterations;
  • Tools and technologies for epigenetic editing in immune cells;
  • Epigenetic-based therapeutic strategies for immunological disorders and cancer.

This Special Issue aims to serve as a platform for interdisciplinary dialogue and discovery, bringing together insights from epigenetics and immunology to foster the development of innovative diagnostic and therapeutic approaches.

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. Epigenomes is an international peer-reviewed open access quarterly journal published by MDPI.

Innate Immune Surveillance and Recognition of Epigenetic Marks

The innate immune system protects against infection and cellular damage by recognizing conserved pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). Emerging evidence suggests that aberrant epigenetic modifications—such as altered DNA methylation and histone marks—can serve as immunogenic signals that activate pattern recognition receptor (PRR)-mediated immune surveillance. This review explores the concept that epigenetic marks may function as DAMPs or even mimic PAMPs. I highlight how unmethylated CpG motifs, which are typically suppressed using host methylation, are recognized as foreign via Toll-like receptor 9 (TLR9). I also examine how cytosolic DNA sensors, including cGAS, detect mislocalized or hypomethylated self-DNA resulting from genomic instability. In addition, I discuss how extracellular histones and nucleosomes released during cell death or stress can act as DAMPs that engage TLRs and activate inflammasomes. In the context of cancer, I review how epigenetic dysregulation can induce a “viral mimicry” state, where reactivation of endogenous retroelements produces double-stranded RNA sensed by RIG-I and MDA5, triggering type I interferon responses. Finally, I address open questions and future directions, including how immune recognition of epigenetic alterations might be leveraged for cancer immunotherapy or regulated to prevent autoimmunity. By integrating recent findings, this review underscores the emerging concept of the epigenome as a target of innate immune recognition, bridging the fields of immunology, epigenetics, and cancer biology.
