Cells can spontaneously change shape even without external signals, but the underlying mechanisms behind this form of ...

Protein molecules are found embedded in the two layers of phospholipids. Membrane proteins have a wide variety of functions. Some allow a cell to respond to specific chemical signals from other cells, ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, ...

Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines nearly every aspect of their functioning. This ...

Researchers from Heinrich Heine University Düsseldorf (HHU) have – in collaboration with colleagues from Ludwig Maximilian University (LMU) in Munich – analysed the complex biochemical processes by ...

Researchers shifted the focus to the internal properties of the membrane itself, specifically its viscosity, highlighting its critical role in controlling deformation and dynamics during essential ...

Collaboration between researchers at the University of Geneva, Institut de biologie structurale de Grenoble, and the University of Fribourg has shown how lipids and proteins in cell membranes react in ...

Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

How large, fully folded proteins can pass through cell membranes without destroying them has long been one of the open ...

A study could open new pathways for understanding how cholesterol influences cell membranes and their receptors, paving the way for future research on diseases linked to membrane organization. A new ...

Nano-sized outer membrane vesicles (OMVs) are lipid-bilayered structures that primarily encapsulate periplasmic components, with minor inclusion of cytoplasmic materials. Rather than passive ...
