AbstractChronic tissue fibrosis is a common pathological feature of connective tissue diseases and malignant tumors, and its prevention has been a major focus of relevant research.However, the details of the mechanism of action of tissue-colonizing immune cells in fibroblast migration are unclear. In this study, connective tissue disease tissue specimens and solid tumor specimens were selected to observe the relationship between mast cells and interstitial fibrosis and the expression characteristics of mast cells. Our findings suggest that the number of mast cells in the tissue correlates with the degree of pathological fibrosis and that mast cells specifically express the chemokines CCL19 and CCL21, especially CCL19. CCR7+ fibroblasts are highly expressed in mast cell clusters. The mast cell line HMC-1 regulates CD14+ monocyte-derived fibroblasts via CCL19. In disease tissue fibrosis, mast cell activation may increase the expression of chemokines, especially CCL19, in the tissue, thereby inducing a large number of CCR7-positive fibroblasts to migrate to specific tissues. This study lays a foundation for the mechanism of tissue fibrosis and provides evidence for the mechanism by which mast cells induce fibroblast migration.Through the experimental results of this paper, we can combine the induction factors of chronic tissue fibrosis and put forward targeted health prevention strategies.Copyright © 2023 The Authors.
