Abstract:
The important roles of extracellular vesicles in the pathogenesis of various diseases are rapidly being elucidated. As important vehicles of intercellular communication, extracellular vesicles, which comprise microvesicles and exosomes, are revealing important roles in cancer tumorigenesis and metastases and in the spread of infectious disease. The September 2012 Focused Meeting 'Microvesiculation and Disease' brought together researchers working on extracellular vesicles. The papers in this issue of Biochemical Society Transactions review work in areas including HIV infection, kidney disease, hypoxia-mediated tumorigenesis and down-regulation of immune cell functions in acute myeloid leukaemia by tumour-derived exosomes. In all cases, microvesicles and exosomes have been demonstrated to be important factors leading to the pathophysiology of disease or indeed as therapeutic vehicles in possible new treatments. The aim was, having enhanced our molecular understanding of the contribution of microvesicles and exosomes to disease in vitro, to begin to apply this knowledge to in vivo models of disease.
Insights
Extracellular vesicles, including microvesicles and exosomes, are key players in disease development and spread. Research is exploring their roles in cancer and infections for potential new therapies.
Area of Science:
- Cell Biology
- Pathophysiology
- Biochemistry
Background:
- Extracellular vesicles (EVs), encompassing microvesicles and exosomes, are crucial for intercellular communication.

- To explore the potential of EVs as therapeutic vehicles.
- To bridge the gap between in vitro and in vivo understanding of EV function in disease.
Main Methods:
- Review of research presented at the 'Microvesiculation and Disease' Focused Meeting.
- Analysis of studies on HIV infection, kidney disease, and cancer.
- Examination of EV-mediated immune cell function modulation in acute myeloid leukemia.
Main Results:
- EVs are implicated in cancer tumorigenesis, metastasis, and infectious disease spread.
- Tumor-derived exosomes can down-regulate immune cell functions.
- EVs are involved in the pathophysiology of diverse diseases.
Conclusions:
- Extracellular vesicles are vital mediators in disease processes.
