Researchers at New York University and the University of Chicago have developed artificial, fully synthetic cell-like structures that autonomously ingest, process, and push out material, recreating an ...

We present a stochastic model of active vesicular transport and its role in cell polarization, which takes into account positive feedback between membrane-bound signaling molecules and cytoskeletal ...

For decades it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers have now elucidated the transport path ...

The cytosolic free calcium concentration of higher plant cells is maintained at about 0.1 μM by the action of membrane calcium transporters. These act to remove calcium from the cytosol and expel it ...

Glucose serves as a major source of energy for metabolic processes in mammalian cells. Since polar molecules cannot be transported across the plasma membrane, carrier proteins called glucose ...

A balanced potassium household is critical for the survival of both people and bacteria. As bacteria are exposed to much greater fluctuations in environmental conditions, the controlled intake of ...
