GPI‑anchored protein nanoclusters license migrasome expansion and serve as exocytic platforms for migrasome

Nature Communications
Migrasomes are dynamic organelles that form on migrating cells and mediate intercellular communication through secretory cargo release. Expansion of migrasomes has classically been attributed to tetraspanin-enriched microdomains (TEMs). Here we show that

The Potential of α-Spinasterol to Mimic the Membrane Properties of Natural Cholesterol

Molecules, 2017
Sterols play a unique role for the structural and dynamical organization of membranes. The current study reports data on the membrane properties of the phytosterol (3β,5α,22E)-stigmasta-7,22-dien-3-β-ol (α-spinasterol), which represents an important ...

Metallic spacers to enhance membrane distillation

, 2018
Despite membrane distillation (MD) being well acknowledged as a green technology due to the capability to treat water using waste heat, the efficient use of this heat remains one of the biggest challenge for MD to be cost-effective.

Influence of Hydraulic Pressure on Performance Deterioration of Direct Contact Membrane Distillation (DCMD) Process

Membranes, 2019
Direct contact membrane distillation (DCMD) is a membrane distillation (MD) configuration where feed and distillate directly contact with a hydrophobic membrane.

The structure of plant photosystem I super-complex at 2.8 Å resolution

eLife, 2015
Most life forms on Earth are supported by solar energy harnessed by oxygenic photosynthesis. In eukaryotes, photosynthesis is achieved by large membrane-embedded super-complexes, containing reaction centers and connected antennae.

CD133 Shapes Extracellular Vesicle Cargo and Angiogenic Function in Basal‐Like Triple‐Negative Breast Cancer

Journal of Extracellular Vesicles
Extracellular vesicles (EVs) are central mediators of tumour‐stroma communication, yet the mechanisms governing their biogenesis and functional cargo remain poorly understood.

Structural basis of Ca2+-dependent activation and lipid transport by a TMEM16 scramblase

eLife, 2019
The lipid distribution of plasma membranes of eukaryotic cells is asymmetric and phospholipid scramblases disrupt this asymmetry by mediating the rapid, nonselective transport of lipids down their concentration gradients.

Packaged release and targeted delivery of cytokines by migrasomes in circulation

Cell Discovery
In dynamic systems like the circulatory system, establishing localized cytokine gradients is challenging. Upon lipopolysaccharide (LPS) stimulation, we observed that monocytes release numerous migrasomes enriched with inflammatory cytokines, such as TNF ...
