Abstract
Inflammation is a key driver of the progression of preleukemic myeloid conditions, such as clonal hematopoiesis of indeterminate potential (CHIP) and clonal cytopenia of undetermined significance (CCUS), to myelodysplastic syndromes (MDS). Inflammation is a critical mediator in the complex interplay of the genetic, epigenetic, and microenvironmental factors contributing to clonal evolution. Under inflammatory conditions, somatic mutations in TET2, DNMT3A, and ASXL1, the most frequently mutated genes in CHIP and CCUS, induce a competitive advantage to hematopoietic stem and progenitor cells, which leads to their clonal expansion in the bone marrow. Chronic inflammation also drives metabolic reprogramming and immune system deregulation, further promoting the expansion of malignant clones. This review underscores the urgent need to fully elucidate the role of inflammation in MDS initiation and highlights the potential of the therapeutical targeting of inflammatory pathways as an early intervention in MDS.
期刊介绍:
Seminars in Hematology aims to present subjects of current importance in clinical hematology, including related areas of oncology, hematopathology, and blood banking. The journal''s unique issue structure allows for a multi-faceted overview of a single topic via a curated selection of review articles, while also offering a variety of articles that present dynamic and front-line material immediately influencing the field. Seminars in Hematology is devoted to making the important and current work accessible, comprehensible, and valuable to the practicing physician, young investigator, clinical practitioners, and internists/paediatricians with strong interests in blood diseases. Seminars in Hematology publishes original research, reviews, short communications and mini- reviews.
