TLDR Immune-epithelial interactions are crucial for tissue repair, but unchecked can cause diseases.
The document explores the critical role of immune-epithelial interactions in tissue regeneration and repair, particularly in the skin and gut. It highlights how immune cells, such as macrophages and regulatory T cells (Tregs), influence hair follicle stem cells (HFSCs) and intestinal stem cells (ISCs) through various signaling pathways, promoting proliferation, differentiation, and maintaining homeostasis. The study emphasizes the importance of immune signals in re-epithelialization and the potential for leveraging these interactions in therapeutic strategies for regenerative medicine and treating epithelial inflammatory diseases. It also discusses the concept of inflammatory memory in epithelial stem cells and its implications for repair functions, suggesting that understanding these interactions could lead to new therapies for inflammatory diseases and enhance regenerative medicine.
