Research Progress in Exosomes in the Pathogenesis of Bronchial Asthma / 中国医学科学院学报

Bronchial asthma is a heterogeneous chronic inflammatory disease involving multiple immune cells and structural cells.It is characterized by airflow limitation,airway hyperresponsiveness,and airway remodeling,with complex pathogenesis.In recent years,the research on exosomes has developed rapidly.Exosomes are small vesicles secreted by a variety of cells and are naturally found in various biological fluids,with stability and biocompatibility.Exosomes from different cells are involved in pathophysiological processes such as airway inflammation,remodeling,and hyperresponsiveness through specific mechanisms and play a regulatory role in multiple links in bronchial asthma.This review focuses on the role of exosomes from different cells in the pathogenesis of bronchial asthma.

The Role of Platelet Exosomes in Atherogenic Thrombosis --Review / 中国实验血液学杂志

Exosomes are subtypes of extracellur vesicles containing a variety of cell-specific proteins, lipids and nucleic acids released during cell activation or apoptosis, and play the role of intercellur communication mediators in different physiological and pathological processes. With the development of research in recent years, the role of platelet-derived exosomes in cardiovascular diseases has attracted extensive attention. This paper reviews the role of platelet-derived exosomes in atherosclerotic thrombosis and the potential role of platelet-derived exosomes as biomarkers for the diagnosis and treatment of atherosclerotic thrombotic disease and the problems to be solved.

Biosensor-based assay of exosome biomarker for early diagnosis of cancer / 医学前沿

Cancer imposes a severe threat to people's health and lives, thus pressing a huge medical and economic burden on individuals and communities. Therefore, early diagnosis of cancer is indispensable in the timely prevention and effective treatment for patients. Exosome has recently become an attractive cancer biomarker in noninvasive early diagnosis because of the unique physiology and pathology functions, which reflects remarkable information regarding the cancer microenvironment, and plays an important role in the occurrence and evolution of cancer. Meanwhile, biosensors have gained great attention for the detection of exosomes due to their superior properties, such as convenient operation, real-time readout, high sensitivity, and remarkable specificity, suggesting promising biomedical applications in the early diagnosis of cancer. In this review, the latest advances of biosensors regarding the assay of exosomes were summarized, and the superiorities of exosomes as markers for the early diagnosis of cancer were evaluated. Moreover, the recent challenges and further opportunities of developing effective biosensors for the early diagnosis of cancer were discussed.
