The road not taken: Less traveled roads from the TGN to the plasma membrane [PDF]
: The trans-Golgi network functions in the distribution of cargo into different transport vesicles that are destined to endosomes, lysosomes and the plasma membrane. Over the years, it has become clear that more than one transport pathway promotes plasma

Glycopolymer vesicles with an asymmetric membrane [PDF]
Direct dissolution of glycosylated polybutadiene-poly(ethylene oxide) block copolymers can lead to the spontaneous formation of vesicles or membranes, which on the outside are coated with glucose and on the inside with poly(ethylene oxide).

Calcium/sodium exchange in purified secretory vesicles from bovine neurohypophyses [PDF]
Purified secretory vesicles isolated from bovine neurohypophyses take up Na+ under the same circumstances where an efflux of Ca2+ takes place, suggesting a Na+/Ca2+ exchange. Potassium cannot substitute for Na+ in this process. Also, a Ca2+/Ca2+ exchange

A role for the membrane in regulating Chlamydomonas flagellar length. [PDF]
Flagellar assembly requires coordination between the assembly of axonemal proteins and the assembly of the flagellar membrane and membrane proteins. Fully grown steady-state Chlamydomonas flagella release flagellar vesicles from their tips and failure to

Membrane vesicles in magnetotactic bacteria
Magnetotactic bacteria are microorganisms that respond to magnetic fields. We have studied the surface ultrastructure of Magnetospirillum magnetotacticum and uncultured magnetotactic bacteria from a marine environment using transmission electron microscopy and freeze-etching.

Extracellular membrane vesicles and nanotubes in Archaea [PDF]
ABSTRACTMembrane-bound extracellular vesicles (EVs) are secreted by cells from all three domains of life and their implication in various biological processes is increasingly recognized. In this review, we summarize the current knowledge on archaeal EVs and nanotubes, and emphasize their biological significance.

Matrix vesicles in membranous ossification.
Calcification process in membranous ossification was examined histologically by light and electron microscopies in comparison with that in enchondral ossification. The following results were obtained: 1) In the rat tibial articular cartilage, the extracellular matrix proceeding from the transitional to the hypertrophic zone consisted of the following ...

Effects of Monovalent and Divalent Cations on Ca2+ Fluxes Across Chromaffin Secretory Membrane Vesicles [PDF]
: Bovine chromaffin secretory vesicle ghosts loaded with Na+ were found to take up Ca2+ when incubated in K+ media or in sucrose media containing micromolar concentrations of free Ca2+. Li+- or choline+loaded ghosts did not take up Ca2+.
