Extracellular vesicles containing the transferrin receptor as nanocarriers of apotransferrin

AbstractPrevious work by our group has shown the pro ‐differentiating effects of apotransferrin (aTf) on oligodendroglial cellsin vivo andin vitro. Further studies showed the remyelinating effect of aTf in animal demyelination models such as hypoxia/ischemia, where the intranasal administration of human aTf provided brain neuroprotection and reduced white matter damage, neuronal loss and astrogliosis in different brain regions.These data led us to search for a less invasive and controlled technique to deliver aTf to the CNS. To such end, we isolated extracellular vesicles (EVs) from human and mouse plasma and different neuron and glia conditioned media and characterized them based on their quality, quantity, identity and structural integrity by Western blot, dynamic light scattering and scanning electron microscopy. All sources yielded highly pure vesicles whose size and structures were in keeping with previous literary evidence. Given that, remarkably, EVs from all sources analyzed contained Tf receptor 1 (TfR1) in their composition, we employed two passive cargo ‐loading strategies which rendered successful EV loading with aTf, specifically through binding to TfR1.These results unveil EVs as potential nanovehicles of aTf to be delivered into the CNS parenchyma, and pave the way for further studies into their possible clinical application in the treatment of demyelinating diseases.

Authors: Miceli A, Raffa S, Donegani MI, Cossu V, Morbelli S, Marini C, Sambuceti G, Bauckneht M Abstract Sarcoidosis is a systemic inflammatory disease of unknown etiology, pathologically characterized by non-caseating granulomas involving several organs and tissues. This pathological process can eventually affect the heart during his course leading to fibrosis associated with systolic dysfunction, conduction disturbance, and even sudden cardiac death. Due to this prognostic impact, diagnosis is crucial to optimize clinical management. The low sensitivity of endomyocardial biopsy and its invasive nature prevents i...

Combination of Fluorine-18 Fluorodeoxyglucose Positron-Emission Tomography/Computed Tomography (¹⁸F-FDG PET/CT) and Tumor Markers to Diagnose Lymph Node Metastasis in Non-Small Cell Lung Cancer (NSCLC): A Retrospective and Prospective Study. Med Sci Monit. 2020 Jun 02;26:e922675 Authors: Zhai X, Guo Y, Qian X Abstract BACKGROUND The early diagnosis of lymph node (LN) metastasis is crucial for patients with non-small cell lung cancer (NSCLC). However, the diagnosis of LN metastasis mainly dependent on ¹⁸F-FDG PET/CT (fluorine-18 fluorodeoxyglucose positron-emission tomography/computed tomo...

Authors: Vijayvergiya R, Kanabar K, Kaushal S, Lal A, Krishnan S Abstract A 42-year-old female with end-stage chronic kidney disease, who was on maintenance hemodialysis for the last 3 years, presented with facial and upper-limb swelling of 2-month duration. A computed tomography (CT) scan confirmed significant stenosis of the superior vena cava (SVC). Following discussion in a multidisciplinary meeting, it was proposed to perform a repeat endovascular intervention to relieve the SVC obstruction and manage the migrated stent.
