The Tol-Pal complex maintains bacterial outer membrane (OM) stability by regulating lipid homeostasis. (Left) In Gram-negative bacteria, the OM acts as a protective barrier, blocking entry of harmful ...

Structural insights into two lipid transport systems in Gram-negative bacteria aid the understanding into their underlying mechanisms. The Tol-Pal complex (left) and the OmpC-Mla system (right) ...

A set of new imaging tools now allows researchers to see how specific fat molecules, called phospholipids, are distributed across cell membranes in three dimensions and at nanometer-scale precision.

Scientists have uncovered an elegant biophysical trick that tuberculosis-causing bacteria use to survive inside human cells, a discovery that could lead to new strategies for fighting one of the world ...

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, ...

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 ...
