Adaptors for clathrin-mediated traffic.
Clathrin-based systems are responsible for a large portion of vesicular traffic originating from the plasma membrane and the trans-Golgi network that reaches the endosomal compartment. The assembly of cytosolic clathrin forms the scaffold required for the local deformation of the membrane and for the formation of coated pits and vesicles. In this process, clathrin interacts in a coordinated fas...
متن کاملNew calibrated-leak microcatheters for cyanoacrylate embolization and chemotherapy.
A soft microcatheter developed 8 years ago has given radiologists the ability to explore and treat hypervascular lesions of the brain and spinal cord [1, 2] and to infuse chemotherapeutic agents beyond the ophthalmic artery. The microcatheter had a single lumen and ended in a balloon with a calibrated leak. If the leak size was appropriate, then the first part of the injection would expand the ...
متن کاملShapability, memory, and luminal changes in microcatheters after steam shaping: a comparison of 11 different microcatheters.
PURPOSE The purpose of this study was to compare the characteristics of shaped microcatheters, including shapability, durability, and luminal changes. MATERIALS AND METHODS Eleven brands of steam-shaped microcatheters and one brand of preshaped microcatheter were evaluated. There were 2 nonreinforced and 10 reinforced devices supported by coils. For evaluation of shapability, the tip angle of...
متن کاملClathrin Adaptors Really Adapt
The clathrin pathway is the principal route for receptor-mediated endocytosis and growth factor downregulation. Heterotetrameric clathrin adaptors directly link the clathrin coat with cargo transmembrane proteins that are sorted into coated pits and vesicles. A paper in this issue of Cell describes the atomic structure of the adaptor-protein 2 (AP-2) core, the portion that makes contacts with t...
متن کاملComplex curve microcatheters for berry aneurysm endovascular therapy.
By using images created with 3D rotational angiography or CT angiography as templates, it is possible to place anatomically correct curves on microcatheters, curves that reproduce the complex 3D vascular anatomy of individual patients. Catheters so curved conform to the anatomy of arteries leading to aneurysms and are less likely to be forced out of position as coil packing progresses.
