When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) interwoven through in the cell’s chromosome (red). Right side shows all the ...

T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the ...

Researchers at the University of Michigan have revealed that cells use a previously unknown feat of molecular craftsmanship ...

A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life ...

A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular debris.

Researchers at the Kennedy Institute of Rheumatology have found that physically resisting the formation of an immunological synapse actually promotes a stronger immune response. The findings could ...

It has long been known that our bodies derive energy from sugar. Researchers at RPTU University Kaiserslautern-Landau have ...

A well-fitted ‘disguise’ allows transplanted mitochondria to slip into cells whose own mitochondria are defective, scientists reported 18 March in Cell 1. Administration of these cloaked mitochondria ...

For five decades, scientists have known about a notorious cancer-causing enzyme called SRC. But they always assumed it only ...
