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 ...

Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the contents in, and forms an intracellular vesicle called an endosome. This vesicle travels through ...

Most cells in the body send out little messengers called extracellular vesicles that carry proteins, lipids, and other ...

The laboratory of Ege Kavalali, professor and chair of the Department of Pharmacology, published a paper in Nature ...

Some Pseudomonas species use specialized microscopic membrane devices to fight back against competing bacteria.

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

In the model, this is the grape. Cell membrane close cell membraneThis surrounds the outside of animal cells and controls what can enter and exit it.: In the model, this is the balloon.

Profilee Satyajit Mayor discusses his explorations of cell membranes, which are helping to update the classical fluid mosaic model of dynamic cellular boundaries. On March 7, researchers will rally in ...

A study explores how cationic fusogenic liposomes temporarily modify membrane properties during fusion, offering new insights ...

A vivid new image is taking shape in the world of cell biology: Imagine bacteria adhering to the surface of a cell, perhaps at the site of an injury or wound. In response, a white blood cell arrives ...

A new approach to elucidate the operation and control of Polymer Electrolyte Membrane (PEM) fuel cells is being developed. A global reactor engineering approach is applied to PEM fuel cells to ...
