Snorkel-tag based affinity chromatography for recombinant extracellular vesicle purification.

J Extracell Vesicles

October 2024

Institute of Molecular Biotechnology, Department of Biotechnology, BOKU University, Vienna, Austria.

Extracellular vesicles (EVs) are lipid nanoparticles and play an important role in cell-cell communications, making them potential therapeutic agents and allowing to engineer for targeted drug delivery. The expanding applications of EVs in next generation medicine is still limited by existing tools for scaling standardized EV production, single EV tracing and analytics, and thus provide only a snapshot of tissue-specific EV cargo information. Here, we present the Snorkel-tag, for which we have genetically fused the EV surface marker protein CD81, to a series of tags with an additional transmembrane domain to be displayed on the EV surface, resembling a snorkel.

Article Synopsis
  • Immunocompromised patients have shown weak responses to initial SARS-CoV-2 mRNA vaccinations, prompting recommendations for extra booster doses; however, real-world data on these recommendations is limited.
  • A two-year follow-up of the COVAXID clinical trial involved 364 participants, focusing on their immune responses and the effects of their vaccination schedule and underlying health conditions.
  • The study found that while some patients who initially had poor responses improved after additional doses, their immune response remained affected by their immunosuppressive status, emphasizing the need for ongoing vaccination efforts in these populations.

Increased plasma creatine concentrations are associated with the risk of type 2 diabetes, but whether this alteration is associated with or causal for impairments in metabolism remains unexplored. Because skeletal muscle is the main disposal site of both creatine and glucose, we investigated the role of intramuscular creatine metabolism in the pathophysiology of insulin resistance in type 2 diabetes. In men with type 2 diabetes, plasma creatine concentrations were increased, and intramuscular phosphocreatine content was reduced.

Estimating glomerular filtration in young people.

Clin Kidney J

September 2024

Department of Public Health and Primary Care, KU Leuven Campus Kulak Kortrijk, Kortrijk, Belgium.

Background: Creatinine-based equations are the most used to estimate glomerular filtration rate (eGFR). The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), the re-expressed Lund-Malmö Revised (r-LMR) and the European Kidney Function Consortium (EKFC) equations are the most validated. The EKFC and r-LMR equations have been suggested to have better performances in young adults, but this is debated.

Randomized Invitation to Systematic NT-proBNP and ECG Screening in 75-Year-Olds to Detect Atrial Fibrillation: STROKESTOP II.

Circulation

December 2024

Karolinska Institutet, Department of Clinical Sciences, Division of Cardiovascular Medicine, Danderyd University Hospital, Stockholm, Sweden (K.K.G., L.F., T.H., V.F., F.A.-K., M.R., J.E.).

Background: Guidelines have suggested screening for atrial fibrillation to enable early treatment and avoid downstream negative clinical events. We aimed to determine whether atrial fibrillation screening potentially enhanced by NT-proBNP (N-terminal pro-B-type natriuretic peptide) would reduce stroke or systemic embolism incidence compared with a control group and to determine whether it was safe for those with low NT-proBNP concentrations to forfeit prolonged screening.

Methods: In this randomized controlled trial, all 75- and 76-year-old individuals in Stockholm Region, Sweden, were randomized 1:1 to be invited to screening or serve as a control group.
