Biomimetic Lipopolysaccharide‐Free Bacterial Outer Membrane‐Functionalized Nanoparticles for Brain‐Targeted Drug Delivery

open access: yesAdvanced Science, 2022
The blood–brain barrier (BBB) severely blocks the intracranial accumulation of most systemic drugs. Inspired by the contribution of the bacterial outer membrane to Escherichia coli K1 (EC‐K1) binding to and invasion of BBB endothelial cells in bacterial ...

Outer membrane vesicles as platform vaccine technology [PDF]

open access: yesBiotechnology Journal, 2015
AbstractOuter membrane vesicles (OMVs) are released spontaneously during growth by many Gram‐negative bacteria. They present a range of surface antigens in a native conformation and have natural properties like immunogenicity, self‐adjuvation and uptake by immune cells which make them attractive for application as vaccines against pathogenic bacteria ...

Vesicle-Mediated Dendritic Cell Activation in Acinetobacter baumannii Clinical Isolate, which Contributes to Th2 Response

open access: yesJournal of Immunology Research, 2019
Acinetobacter baumannii, as a nonfermentation Gram-negative bacterium, mainly cause nosocomial infections in critically ill patients. With the widespread of multidrug-resistant Acinetobacter baumannii, the urgency of developing effective therapy options ...

Photoreceptor Outer Segment-like Structures in Long-Term 3D Retinas from Human Pluripotent Stem Cells. [PDF]

open access: yes, 2017
The retinal degenerative diseases, which together constitute a leading cause of hereditary blindness worldwide, are largely untreatable. Development of reliable methods to culture complex retinal tissues from human pluripotent stem cells (hPSCs) could ...

Heat shock enhances outer-membrane vesicle release in Bordetella spp.

open access: yesCurrent Research in Microbial Sciences, 2021
Pertussis, also known as whooping cough, is caused by the Gram-negative bacterium Bordetella pertussis, an obligate human pathogen. Despite high vaccination rates in high-income countries, resurgence of pertussis cases is an occurring problem that urges ...

Synaptic proteins promote calcium-triggered fast transition from point contact to full fusion. [PDF]

open access: yes, 2012
The molecular underpinnings of synaptic vesicle fusion for fast neurotransmitter release are still unclear. Here, we used a single vesicle-vesicle system with reconstituted SNARE and synaptotagmin-1 proteoliposomes to decipher the temporal sequence of ...

Genome-Wide Assessment of Outer Membrane Vesicle Production in Escherichia coli. [PDF]

open access: yesPLoS ONE, 2015
The production of outer membrane vesicles by Gram-negative bacteria has been well documented; however, the mechanism behind the biogenesis of these vesicles remains unclear.

Outer envelope membranes from chloroplasts are isolated as right-side-out vesicles [PDF]

open access: yes, 1992
Outer envelope membranes were isolated from purified chloroplasts of pea leaves. The sidedness of the vesicles was analyzed by (i) aqueous polymer-two phase partitioning, (ii) the effect of limited proteolysis on the outer-envelope proteins (OEP) 86 and ...

Production of Outer Membrane Vesicles and Outer Membrane Tubes by Francisella novicida [PDF]

open access: yesJournal of Bacteriology, 2012
Francisella spp. are highly infectious and virulent bacteria that cause the zoonotic disease tularemia. Knowledge is lacking for the virulence factors expressed by Francisella and how these factors are secreted and delivered to host cells. Gram-negative bacteria constitutively release outer membrane vesicles (OMV), which may function in the delivery of

Vesicular Nucleo-Cytoplasmic Transport—Herpesviruses as Pioneers in Cell Biology

open access: yesViruses, 2016
Herpesviruses use a vesicle-mediated transfer of intranuclearly assembled nucleocapsids through the nuclear envelope (NE) for final maturation in the cytoplasm.
