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 ...

The fatty membrane surrounding every living cell is a vibrant environment where countless biological processes take place.

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 ...

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 ...

Profilee Satyajit Mayor discusses his explorations of cell membranes, which are helping to update the classical fluid mosaic model of dynamic cellular boundaries. New research uncovered an alarming ...

A new study shows how an anticancer drug triggers an "outside in" signal that gets it sucked into a cancer cell. The work, ...

This influx of calcium at the contact site attracts and activates a kinase called CaMKII, a protein known to be important in ...

Current optical and electron microscopy imaging techniques are not suited for measuring the dynamic characteristics of living microorganisms at tiny scales due to complex sample preparation methods or ...

2 Endosymbiotic events are believed to have led to the development of membrane-bound organelles such as mitochondria. Thanks to mitochondria, eukaryotic ancestors had enough energy to develop into the ...

Plants droop and shed their leaves when parched, but with a splash of water, their stems regain strength and their leaves unfurl. This dramatic transformation is a clear signal for us to reach for ...
