Summary: By studying EPC-EXO from patients with coronary heart disease and healthy volunteers, it was found that C-EPC-EXO was less effective than H-EPC-EXO in improving angiogenesis. Manipulating the bioactivities of C-EPC-EXO through miR-199a-3p inhibition and cRGD decoration can significantly promote ECs-mediated angiogenesis for treating ischemic vascular diseases.

Summary: Aging is a key factor in vascular dysfunction and the development of ischemic stroke. ACE2-enriched exosomes derived from endothelial progenitor cells (EPCs) have been shown to protect aging endothelial cells (ECs) from hypoxia-induced injury. This study aimed to investigate the potential of ACE2-enriched EPC exosomes (ACE2-EPC-EXs) in reducing brain ischemic injury by inhibiting cerebral EC damage through miR-17-5p and associated molecular mechanisms. The results demonstrated that ACE2-EPC-EXs were more effective in improving cerebral microvascular density, blood flow, and reducing brain cell senescence, infarct volume, and neurological deficit in aged mice compared to EPC-EXs. In aging ECs, ACE2-EPC-EXs also showed greater efficacy in reducing senescence, oxidative stress, and apoptosis, and promoting cell viability and tube formation compared to EPC-EXs. This research suggests that ACE2-EPC-EXs have promising protective effects against neurovascular injury in aging ischemic stroke by activating the miR-17-5p/PTEN/PI3K/Akt signaling pathway.

Summary: The transplantation of iVECs can ameliorate white matter infarct by suppressing neuroinflammation and promoting remyelination through the recruitment of Tregs. However, suppression of neuroinflammation alone does not promote remyelination, indicating the important role of Tregs in the mechanism of iVEC transplantation.

Summary: Stroke is the second leading cause of death and disability, with limited therapeutic strategies. Blood-based biomarkers, such as microRNAs and exosomes, are recognized as useful tools to predict prognosis in patients with stroke. This systematic review identified 72 circulating biomarkers with prognostic value in stroke recovery, including 68 miRNAs predictive for motor recovery and seven biomarkers predictive for cognitive recovery. The most significant correlations were found with miR-21, miR-29b, miR-125b-5p, miR-126, and miR-335. Serum miR-9 and neutrophil miR-29b were identified as promising biomarkers for further studies.

Summary: This study demonstrates that Schwann cells-derived exosomes (SCs-Exos) can promote proliferation, migration, and tube formation of brain-derived endothelial cells (bEnd.3 cells). It is found that SCs-Exos express high levels of the pro-angiogenesis molecules, Integrin-beta 1. The angiogenic effect of SCs-Exos on bEnd.3 cells is dependent on Integrin-beta 1 expression. In an spinal cord injury (SCI) model, treatment with SCs-Exos attenuates tissue damage and enhances functional recovery by promoting angiogenesis, which requires the involvement of Integrin-beta 1.

Summary: Ischemic diseases, characterized by insufficient blood flow leading to decreased oxygen and nutrient uptake, are a significant global contributor to disability and mortality. Up-regulation of angiogenesis, particularly through stem cell-derived exosomes, shows promise in treating these diseases by promoting blood vessel formation. Further research is needed to address limitations in exosome isolation and application, and to effectively translate preclinical findings into clinical practice.

Summary: MicroRNAs (miRNAs) play a crucial role in regulating gene expression and have shown potential as biomarkers for diagnosis and monitoring in various diseases. This review focuses on circulating and extracellular vesicle-derived miRNAs as biomarkers in bone-related diseases, with a specific emphasis on osteoporosis and osteosarcoma. The review covers the history and biology of miRNAs, different types of biomarkers, and the current understanding of miRNAs as biomarkers in bone-related diseases. Limitations in miRNA biomarker research and future perspectives are also discussed.

Summary: Severe trauma disrupts bone marrow function, resulting in persistent anemia and immunosuppression. Exosomes, which are extracellular vesicles, have been implicated in various diseases and cellular functions. This study investigates the effects of trauma plasma-derived exosomes on bone marrow hematopoiesis and explores the potential mechanisms underlying the altered bone marrow function after severe trauma.

Summary: This study investigated the potential of circulating donor lung-specific exosome profiles for the early diagnosis of acute rejection in a rat orthotopic lung transplant model. The results showed that the levels of circulating donor exosomes peaked on day 1, decreased significantly by day 2, and reached baseline levels by day 3, indicating that this biomarker may provide an early detection of acute rejection before histologic manifestation of injury to the pulmonary allograft.

Summary: The study aims to determine whether transplant center volume affects ACR-related outcomes in children after lung transplantation. The study found that children treated for ACR at high-volume centers have higher survival rates compared to low-volume centers, but similar survival rates to medium-volume centers. ACR incidence is lowest at high-volume centers, and post-ACR treatment survival outcomes are also superior.

Summary: Based on a study of 250 subjects without lung disease, it was found that chest X-ray (CXR) can accurately estimate lung volume and has strong correlations with computed tomography (CT) measurements. The correlation between CXR measurements and true lung volumes is significantly stronger than the correlation with height, weight, or predicted total lung capacity.
