Linking Multivesicular Bodies to Resistance against Fungal Invasion [PDF]

The Plant Cell, 2010
Powdery mildew fungi infect a wide variety of monocots and dicots, forming feeding structures called haustoria in epidermal cells of their hosts (reviewed in [Eichmann and Huckelhoven, 2008][1]).

THE FORMATION OF MULTIVESICULAR BODIES FROM THE NUCLEAR ENVELOPE [PDF]

The Journal of Cell Biology, 1970
Cells of the gas gland of the perch Perca fluviatilis L., stimulated to increased generation of gas by the repeated emptying of the swim-bladder, were examined in the electron microscope. Intense activity of the nuclear envelope was demonstrated. Simple vesicles originating from the external nuclear membrane and the so-called multivesicular bodies ...

A Hydrodynamic Bioreactor for High‐Yield Production of Extracellular Vesicles from Stem Cell Spheroids with Defined Cargo Profiling

Advanced Science, EarlyView.
This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...

CircTspan3 Promotes Cartilage Development Through ANNEXIN A2‐Mediated Ferroptosis and Apoptosis Inhibition and Exosome‐Mediated Paracrine Signaling

Advanced Science, EarlyView.
This study reveals that XBP1s drives production of circTspan3, a circular RNA that strengthens cartilage by boosting anabolic activity and limiting cell death. Phosphorylated ANXA2 directs circTspan3 into exosomes, enabling paracrine repair. Exosomal circTspan3 expands growth‐plate cartilage and promotes in vivo regeneration, highlighting its promise ...

An early secretory pathway mediated by GNOM-LIKE 1 and GNOM is essential for basal polarity establishment in Arabidopsis thaliana [PDF]

, 2015
Spatial regulation of the plant hormone indole-3-acetic acid (IAA, or auxin) is essential for plant development. Auxin gradient establishment is mediated by polarly localized auxin transporters, including PIN-FORMED (PIN) proteins. Their localization and

RAL-1 controls multivesicular body biogenesis and exosome secretion [PDF]

Journal of Cell Biology, 2015
Exosomes are secreted vesicles arising from the fusion of multivesicular bodies (MVBs) with the plasma membrane. Despite their importance in various processes, the molecular mechanisms controlling their formation and release remain unclear. Using nematodes and mammary tumor cells, we show that Ral GTPases are involved in exosome biogenesis.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

Advanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

ISGylation controls exosome secretion by promoting lysosomal degradation of MVB proteins

Nature Communications, 2016
Multivesicular bodies (MVB) are endosomal compartments that can either fuse with the plasma membrane for the secretion of exosomes, or fuse with the lysosome and be degraded along with their contents.

Nectar and oleiferous trichomes as floral attractants in Bulbophyllum saltatorium Lindl. (Orchidaceae) [PDF]

, 2017
Although many Orchidaceae have deceit flowers that produce no reward, the most common reward, when present, is nectar. Bulbophyllum, however, is unusual in that the labellar secretions of most species investigated to date lack sugars, and, therefore ...

Dual mechanisms specify Doa4‐mediated deubiquitination at multivesicular bodies [PDF]

The EMBO Journal, 2007
Doa4 is a ubiquitin-specific protease in Saccharomyces cerevisiae that deubiquitinates integral membrane proteins sorted into the lumenal vesicles of late-endosomal multivesicular bodies (MVBs). We show that the non-catalytic N terminus of Doa4 mediates its recruitment to endosomes through its association with Bro1, which is one of several highly ...
