Role of Adiposomes in Endothelial Dysfunction
NCT05199454 · View on ClinicalTrials.gov ↗
Study Summary
The development of type II diabetes (T2D) is strongly associated with obesity and both are well-established risk factors for cardiovascular disease. Knowing that vascular dysfunction is an early event in the development of cardiovascular disease in obese diabetic (OB-T2D) patients, The investigators set their long-term goal to define molecular mechanisms of vascular dysfunction and corrective strategies that target these mechanisms such as physical activity and weight loss. The investigators recently discovered that human adipose tissues release extracellular vesicles (adiposomes) that are efficiently captured by endothelial cells. Adiposomes are known to carry bioactive cargos such as proteins and micro RNAs; however, their lipid content has not been studied nor has their ability to transfer their lipid cargo to endothelial cells. In the current application, the investigators propose to investigate the role of adiposomes in communicating the unhealthy milieu, mainly dysregulated lipids, to endothelial cells in OB-T2D subjects. On top of these lipid species that the investigators propose to be carried by adiposomes are glycosphingolipids (GSLs). These lipids originate from the glycosylation of ceramides, a chemical process that is upregulated in the presence of inflammation and high glucose levels. Preliminary findings showed that in endothelial cells, GSL-rich adiposomes disturb plasma membrane structure and subsequently induce endothelial dysfunction. Moreover, the investigators found that preconditioning endothelial cells with high shear stress (which is an exercise mimetic) protected endothelial cells from the detrimental effects induced by adiposomes. Therefore, the central hypothesis is that adipose tissues in OB-T2D patients release GSL-loaded adiposomes that induce vascular endothelial dysfunction. The researchers propose that exercise and weight loss interventions (bariatric surgery) will restore adipose tissue homeostasis, reduce GSL-loaded adiposomes, and

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05199454
The ClinicalTrials.gov registry entry for NCT05199454 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 60 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Illinois at Chicago, which has 421 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Obesity appearing as the primary indexed condition, and to 1 intervention — of which Exercise training is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05199454 reports 1 study location spanning 1 distinct geographic area — top geographies include Illinois. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
