Delivery of Antisense Oligonucleotides Mediated by a Hydrogel System: In Vitro and In Vivo Application in the Context of Spinal Cord Injur

Biomaterials-based hydrogels are attractive drug-eluting vehicles in the context of RNA therapeutics, such as those utilizing antisense oligonucleotide or RNA interference based drugs, as they can potentially reduce systemic toxicity and enhance in vivo efficacy by increasing in situ concentrations. Here we describe the preparation of antisense oligonucleotide-loaded fibrin hydrogels exploring their applications in the context of the nervous system utilizing an organotypic dorsal root ganglio...

Studying T Cells N-Glycosylation by Imaging Flow Cytometry

Imaging flow cytometry is an emerging imaging technology that combines features of both conventional flow cytometry and fluorescence microscopy allowing quantification of the imaging parameters. The analysis of protein posttranslational modifications by glycosylation using imaging flow cytometry constitutes an important bioimaging tool in the glycobiology field. This technique allows quantification of the glycan fluorescence intensity, co-localization with proteins, and evaluation of the memb...

Factors involved in ubiquitination and deubiquitination of PEX5, the peroxisomal shuttling receptor

Peroxisomal matrix proteins are synthesized on cytosolic ribosomes and post-translationally targeted to the organelle by the soluble factor PEX5. Besides a role as a receptor, and probably as a chaperone, PEX5 also holds the key to the matrix of the organelle. Indeed, the available data suggest that PEX5 itself pushes these proteins across the peroxisomal membrane using as driving force the strong protein-protein interactions that it establishes with components of the peroxisomal membrane doc...
