New findings on the recycling centres of cells

Both animal and plant cells depend on autophagy in which damaged or superfluous cell material is removed. The degradation of substrates is done by proteins. In animals, it takes place in a cell organelle called the lysosome ...

Insect or virus? How plants know

Most plants have plenty of enemies, from insects and other grazing creatures to various diseases, droughts and many other stressors.

Motor proteins and membrane dynamics

Membranes composed of a lipid bilayer define the outer surface of nucleated cells (the plasma membrane) and delimit the vital organelles within these cells, such as mitochondria and nuclei. The membrane curvature determines ...

Discovery casts doubt on cell surface organization models

Like planets, the body's cell surfaces look smooth from a distance, but contoured closer up. An article published in Communications Biology describes previously unknown implications of the way data from cell surfaces are ...

Cell membrane

The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment.

It is a semipermeable lipid bilayer found in all cells. It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes such as cell adhesion, ion channel conductance and cell signaling. The plasma membrane also serves as the attachment point for both the intracellular cytoskeleton and, if present, the extracellular cell wall.
