Inflammation drives myelodysplastic syndromes (MDS) by promoting clonal selection and ineffective hematopoiesis. Targeting inflammation may improve prognosis and treatment sensitivity in MDS patients.
Area of Science:
- Hematology
- Immunology
- Stem Cell Biology
Background:
- Myelodysplastic syndromes (MDS) involve ineffective hematopoiesis within a context of chronic inflammation and immune dysregulation.
- Aging-associated inflammaging and bone marrow microenvironment remodeling actively shape MDS progression.
Purpose of the Study:
- To review the interplay between inflammation and MDS pathogenesis.
- To explore how inflammation influences clonal selection, hematopoiesis, and disease evolution.
Main Methods:
- Narrative review integrating insights from translational immunology, stem cell biology, multi-omics, and clinical studies.
- Examination of reciprocal interactions between inflammation and MDS.
Main Results:
- Chronic inflammation selects for and expands mutation-bearing clones in hematopoietic stem cells.
- Persistent inflammation, immune dysfunction, and stromal alterations worsen ineffective hematopoiesis and clonal dominance.
- Genetic lesions (e.g., TP53, spliceosome mutations) amplify inflammation and confer clonal advantage.
- Peripheral blood inflammatory markers correlate with MDS prognosis and treatment response.
Conclusions:
- Inflammation is a key factor in MDS initiation, progression, and treatment sensitivity.
- Integrating inflammatory signatures with genomic profiling can refine risk stratification.
- Therapeutic strategies targeting inflammation may restore marrow homeostasis and limit disease evolution.

Interactions Between Signaling Pathways
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
