Recent advances in immunology and histopathology have highlighted the critical role of stromal-immune cell interactions in shaping tissue-specific immune responses and influencing disease progression. Stromal cells, including fibroblasts, endothelial cells, and pericytes, once considered passive structural components, are now recognized as active players in immune regulation. Through direct cell-cell contact and the secretion of cytokines, chemokines, and extracellular matrix components, stromal cells orchestrate the recruitment, activation, and retention of immune cells within tissues. This dynamic interplay is essential for maintaining immune homeostasis but can also contribute to pathological outcomes in chronic inflammation, autoimmunity, fibrosis, and tumorigenesis. Histological studies using advanced staining techniques and tissue imaging have revealed distinct spatial patterns of stromal-immune interactions across different organs, highlighting their tissue-specific nature. For instance, cancer-associated fibroblasts (CAFs) in tumors create immunosuppressive microenvironments, while in autoimmune diseases like rheumatoid arthritis, stromal cells perpetuate inflammation by sustaining pathogenic immune cell niches. Understanding these cellular crosstalk mechanisms from a histological perspective allows for precise identification of key cellular players and their microenvironmental contexts. Moreover, targeting stromal components and their signaling pathways holds promise for novel therapeutic approaches that modulate local immunity without broadly suppressing systemic immune functions. This review emphasizes the importance of integrating histological insights with immunological research to uncover the complex network of stromal-immune interactions in health and disease. Such integration could lead to more accurate disease models and personalized treatment strategies tailored to the tissue-specific immune landscapes.
