[Extracellular vesicles and their role in hematological malignancies]

Area of Science:

• Biochemistry
• Cell Biology
• Oncology

Background:

• Extracellular vesicles (EVs) like apoptotic bodies, microvesicles, and exosomes are produced by all organisms.
• EVs play crucial roles in intercellular communication, immune responses, and angiogenesis in physiological and pathological states.
• Alterations in EVs suggest their potential as diagnostic and prognostic biomarkers.

Purpose of the Study:

• To provide an overview of extracellular vesicle research.
• To focus on the findings related to EVs in hematological malignancies.
• To explore the diagnostic and prognostic value of EVs in these cancers.

Main Methods:

• Literature review focusing on extracellular vesicles.
• Analysis of published research on EVs in hematological malignancies.
• Examination of quantitative and qualitative changes in microvesicles and exosomes.

Main Results:

• Quantitative and qualitative changes in microvesicles and exosomes show potential for diagnostics, prognostics, and minimal residual disease monitoring in hematological malignancies.
• Extracellular vesicles' role in downregulating natural killer cell activity in acute myeloid leukemia is demonstrated.
• Microvesicles are implicated in drug resistance in chronic lymphocytic leukemia.

Conclusions:

• Extracellular vesicles represent a promising area for biomarker development in hematological malignancies.
• Further research into EVs could lead to improved diagnostic and therapeutic strategies for blood cancers.
• EVs are integral to understanding disease mechanisms and monitoring treatment efficacy.
