Normal metabolic activity produces reactive oxygen species (ROS) that, if not eliminated, can damage cellular components. As a result, ROS from overactive mitochondria are frequently cited as a source ...

The nanotubes extend out and tunnel into the T-cell, creating tiny passages between cells that deliver mitochondria directly.

How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...

An enzyme that helps clear damaged mitochondria can act as a molecular switch and potentially prevent neurons from dying.

Healthy tissues recycle damaged mitochondria before they can weaken tissues, but this recycling slows as people age. Credit: Amazentis Thanks to public health measures and modern medicine ...

Our cells use oxygen to generate energy by burning nutrients to keep various processes in the cell working. While making this energy in the mitochondria (the cell’s power plants), the cell also ...

A specially designed drug prevented laboratory mice from developing heart failure after heart attacks, according to new ...

When energy is scarce or when the insulin signal is interrupted, mitochondrial recycling is reduced and cells continue to use ...
