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, ...

Bacteria and yeast need to prevent leakage of numerous small molecules through their cell membrane. Biochemists have studied how the composition of the membrane affects passive diffusion and the ...

Abstract Dimerization of transmembrane (TM) proteins is a fundamental process in cellular membranes, central to numerous physiological and ...

The transport of amino acids and other molecules across the cell's membrane plays a crucial role in the metabolism of cells and, therefore, in human health. Current research hints that cancer, cystic ...

Some analytical and numerical results are presented for pattern formation properties associated with novel types of reaction–diffusion (RD) systems that involve the coupling of bulk diffusion in the ...

In a pioneering discovery, researchers at UNIST have captured, for the first time, the elusive intermediate stages involved in the pairing of cell membrane proteins. Contrary to long-held beliefs that ...

Spiky nanorobots powered by magnets have been developed to carry drugs and pierce tumor cell membranes, a key barrier to effective cancer treatment. By boosting drug entry, these "microscopic scalpels ...

Researchers engineered magnetic nanorobots that carry anticancer drugs and penetrate tumor cell membranes, improving ...
