Infectious diseases are the leading cause of death in both adults and children, with respiratory infections being the leading cause of death. A growing body of evidence suggests that bacterially released extracellular membrane vesicles play an important ...

Three-dimensional architecture and biogenesis of membrane structures associated with hepatitis C virus replication [PDF]
All positive strand RNA viruses are known to replicate their genomes in close association with intracellular membranes. In case of the hepatitis C virus (HCV), a member of the family Flaviviridae, infected cells contain accumulations of vesicles forming ...

Bacterial communication through membrane vesicles [PDF]
ABSTRACT Bacteria can communicate through diffusible signaling molecules that are perceived by cognate receptors. It is now well established that bacterial communication regulates hundreds of genes. Hydrophobic molecules which do not diffuse in aqueous environments alone have been identified in bacterial communication, that raised the ...

Active zone material is an organelle that is common to active zones along the presynaptic membrane of chemical synapses. Electron tomography on active zones at frog neuromuscular junctions has provided evidence that active zone material directs the ...

Small extracellular vesicles are membrane-bound vesicles secreted into extracellular spaces by virtually all types of cells. These carry a large number of membrane proteins on their surface that are incorporated during their biogenesis in cells.

Fusion of neurohypophyseal membranes in vitro [PDF]
Freeze cleaving electron microscopy has shown that fusion of isolated secretory vesicles from bovine neurohypophyses was induced by Ca 2+ in micromolar concentrations. Mg 2+ and Sr 2+ were ineffective. Mg 2+ inhibited Ca 2+-induced fusion. In suspensions

A Sec14 domain protein is required for photoautotrophic growth and chloroplast vesicle formation in Arabidopsis thaliana. [PDF]
In eukaryotic photosynthetic organisms, the conversion of solar into chemical energy occurs in thylakoid membranes in the chloroplast. How thylakoid membranes are formed and maintained is poorly understood.

Latent acetylcholinesterase in secretory vesicles isolated from adrenal medulla [PDF]
A new procedure is described for the preparation of highly purified and stable secretory vesicles from adrenal medulla. Two forms of acetylcholinesterase, a membrane bound form as well as a soluble form, were found within these vesicles.

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.
