Circulating microparticles from obstructive sleep apnea syndrome patients induce endothelin-mediated angiogenesis

International audienceMicroparticles are deemed true biomarkers and vectors of biological information between cells. Depending on their origin, the composition of microparticles varies and the subsequent message transported by them, such as proteins, mRNA, or miRNA, can differ. In obstructive sleep apnea syndrome (OSAS), circulating microparticles are associated with endothelial dysfunction by reducing endothelial-derived nitric oxide production. Here, we have analyzed the potential role of circulating microparticles from OSAS patients on the regulation of angiogenesis and the involved pathway. VEGF content carried by circulating microparticles from OSAS patients was increased when compared with microparticles from non-OSAS patients. Circulating microparticles from OSAS patients induced an increase of angiogenesis that was abolished in the presence of the antagonist of endothelin-1 receptor type B. In addition, endothelin-1 secretion was increased in human endothelial cells treated by OSAS microparticles. We highlight that circulating microparticles from OSAS patients can modify the secretome of endothelial cells leading to angiogenesis.</p

A Case of Pulmonary Adenocarcinoma Presenting with Diffuse Cystic Lesions

The main causes of diffuse cystic lung diseases include lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis, Birt-Hogg-Dubé syndrome, lymphoid interstitial pneumonia, light chain deposition disease, Pneumocystis jirovecii pneumonia, hypersensitivity pneumonitis, and desquamative interstitial pneumonia. Diffuse cystic lung diseases are rarely caused by a malignant process, which are secondary to metastases from sarcomas and gastrointestinal and gynecologic adenocarcinomas. Here, we present a rare case of invasive pulmonary adenocarcinoma associated with progressive diffusion of cystic lesions, revealed by chronic cough and progressive shortness of breath. It is important for clinicians to be aware of this unusual imaging manifestation of lung cancer, to avoid misdiagnoses
