As mitochondria have crucial roles in metabolism and signaling, their structure and function must be continuously monitored and rapidly adjusted to meet cellular demands. Critical to this regulation ...

Mitochondria are cell organelles surrounded by a double membrane. In addition to numerous essential functions in the metabolism of the cell, they also play a key role in the integration of signals ...

This partial figure from the paper illustrates the steps taken to compare the mitochondria of young and old mice. First, thin tissue slices were imaged with an advanced imaging method called serial ...

Many of us remember from high school biology class that mitochondria are the cell's "power plants." These small kidney-bean-shaped structures are what convert nutrients from food into ATP—the cell's ...

This Collection supports and amplifies research related to SDG 3 and SDG 9. Mitochondrial dysfunction has been identified as a hallmark of aging, playing a central role in age-associated decline ...

Mitochondria have primarily been known as the energy-producing components of cells. But scientists are increasingly discovering that these small organelles do much more than just power cells. They are ...

Researchers at the University of Jyväskylä have found that herpesvirus infection modifies the structure and normal function of the mitochondria in the host cell. The new information will help to ...

A stressful year leads to anxiety. Lasting isolation gives way to depression. An old trauma nags until it becomes paralyzing. Psychological and social experiences shape the brain, potentially leading ...

For decades, psychiatry has focused on neurotransmitters. Depression was a serotonin problem. Schizophrenia was a dopamine problem. Bipolar disorder was a mood stabilizer problem. This concept, while ...

The human heart is one of the hardest-working organs in the body. It never takes a day off and requires a continuous supply of energy to keep beating. To meet these enormous energy demands, heart ...
