Abstract
Introduction: Acute myeloid leukemia (AML) cells exhibit a profound capacity for resistance to conventional chemotherapeutic agents, posing a substantial challenge to existing therapeutic paradigms. Interestingly, this happens in the face of a luxuriant proliferation of leukemic blasts in the peripheral blood. This paradox of concurrent proliferative activity and cellular quiescence underscores a complex biological phenomenon that is intricately mediated by AML-derived Extracellular vesicles (EVs).
Areas covered: An extensive literature review search was done on Pubmed/Scopus/Web of Sciences databases to identify studies published between 2013 and 2024 elucidating and demonstrating the effect of AML-derived EVs, Microvesicles (MVs) and Exosomes (Exos) in regulating the normal and dysregulated bone marrow (BM) niche.
Expert opinion: The review delves into understanding the molecular mechanisms underlying the dual behavior of AML cells - proliferation and quiescence, with a special focus on the role of the EVs and their subtypes viz. Exos and MVs in establishing a discrete BM microenvironment that is subversive to chemotherapy. It offers a novel perspective on the intricate interplay between the leukemic cells and their microenvironment, with implications for therapeutic interventions targeting AML persistence and drug resistance.
期刊介绍:
Advanced molecular research techniques have transformed hematology in recent years. With improved understanding of hematologic diseases, we now have the opportunity to research and evaluate new biological therapies, new drugs and drug combinations, new treatment schedules and novel approaches including stem cell transplantation. We can also expect proteomics, molecular genetics and biomarker research to facilitate new diagnostic approaches and the identification of appropriate therapies. Further advances in our knowledge regarding the formation and function of blood cells and blood-forming tissues should ensue, and it will be a major challenge for hematologists to adopt these new paradigms and develop integrated strategies to define the best possible patient care. Expert Review of Hematology (1747-4086) puts these advances in context and explores how they will translate directly into clinical practice.
