Summary
This Special Issue focuses on advancing our understanding of the cellular and molecular mechanisms that govern immune–epithelial regulation during disease pathogenesis.
Immune–epithelial interactions are essential for maintaining tissue homeostasis and orchestrating immune responses, yet their dysregulation underlies a wide range of chronic inflammatory, autoimmune, and infectious diseases.
We aim to highlight studies that explore how immune cells and epithelial cells communicate through signaling pathways, transcriptional and epigenetic regulation, cytokine networks, and receptor–ligand interactions. Integrative analyses using single-cell and bulk transcriptomics, proteomics, metabolomics, or spatial multi-omics are especially encouraged when they provide mechanistic insight into cell-type–specific functions and molecular regulatory circuits.
We welcome contributions that:
(i)uncover cellular and subcellular processes driving immune activation, tolerance, and epithelial remodeling;
(ii)dissect signaling cascades and transcriptional programs shaping immune–epithelial cross-talk;
(iii)employ functional assays or mechanistic models to validate molecular interactions; and
(iv)develop computational frameworks that elucidate the structural and regulatory basis of immune–epithelial coordination.
By integrating molecular, cellular, and systems-level perspectives, this Special Issue seeks to provide deep mechanistic insights into immune and epithelial biology, advancing the foundational understanding of inflammation, infectious, and immune-mediated disease.
