Immunomodulatory Mechanisms of Secondary Hemophagocytic Lymphohistiocytosis
Journal: Journal of Clinical Medicine Research DOI: 10.32629/jcmr.v6i2.4042
Abstract
This study aims to comprehensively investigate the immunomodulatory mechanisms of secondary hemophagocytic lymphohistiocytosis (sHLH), focusing on cytokine and immune cell alterations to enhance diagnostic and treatment strategies. Through a systematic review of existing literature and clinical case analyses, we explored the roles of cytokines like IL-6, TNF-α, and IFN-γ, and immune cell changes in macrophages, T cells, and NK cells. We also examined the impact of genomic and epigenetic factors on sHLH pathogenesis. The results indicate that abnormal cytokine expression and immune cell dysfunction are central to sHLH development. Targeted therapies against specific cytokines show promise in managing sHLH. In conclusion, understanding these complex immunomodulatory mechanisms is crucial for developing more effective, personalized treatment plans to improve patient outcomes and survival rates. Future research should focus on standardized, multi-center studies to further elucidate these mechanisms and refine therapeutic approaches.
