Latest Cell membrane Stories
Opening up a new door in synthetic biology, a team of researchers has developed a microfluidic device that produces a continuous supply of tiny lipid spheres that are similar in many ways to a cell's outer membrane.
Neurofibrillary tangles – odd, twisted clumps of protein found within nerve cells – are a pathological hallmark of Alzheimer's disease.
The physical model to describe the hydrophobic interactions of molecules has been a mystery that has challenged scientists and engineers since the 19th century.
Researchers at the University of Illinois at Chicago think so, and a biosensor they've created that measures membrane lipid levels may open up new pathways to disease treatment.
Cell-penetrating peptides, such as the HIV TAT peptide, are able to enter cells using a number of mechanisms, from direct entry to endocytosis, a process by which cells internalize molecules by engulfing them.
The crystal structure of the dynamin protein — one of the molecular machines that makes cells work — has been revealed, bringing insights into a class of molecules with a wide influence on health and disease.
Toxin proteins are genetically engineered into our food because they kill insects by perforating body cell walls, and Professor Rikard Blunck of the University of Montreal's Group for the study of membrane proteins (GÉPROM) has detected the molecular mechanism involved.
The delivery system for an important class of proteins in the cell membrane can be fully replicated with a mere three components.
It is helpful â€” even life-saving â€” to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that's easy to read is a challenge.
As the gatekeepers of ion flow through cell membranes, ion channels are of key interest in numerous cellular processes.
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
