Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ensure the signal reaches the correct effector without triggering pathways ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...

Cells can spontaneously change shape even without external signals, but the underlying mechanisms behind this form of ...

Located at the cellular interface, membrane proteins play critical regulatory roles in the signaling between a cell and its interacting environment, making them popular and ideal drug targets.

Researchers shifted the focus to the internal properties of the membrane itself, specifically its viscosity, highlighting its critical role in controlling deformation and dynamics during essential ...

Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do ...
