After treatment, the mice’s memories were essentially shunted back into a younger state. The researchers found that reprogrammed engrams displayed molecular behavior of more youthful cells. Using a ...

The capacity of an organism to regenerate depends on cell dedifferentiation followed by proliferation. Mammals, in general, have limited regenerative capacity. Now, a team of researchers at the Salk ...

Age-related memory decline and neurodegenerative diseases like Alzheimer's are often thought of as irreversible. But the brain is not static; neurons continually adjust the strength of their ...

Viruses have spent billions of years perfecting the art of invading cells, hijacking their machinery and spreading with ruthless efficiency. Now researchers are turning that evolutionary expertise ...

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

Most tissues in the body can regenerate themselves after an injury, but unfortunately heart muscle cells aren’t one of them. Now, scientists at the Max Planck Institute have shown in mice that ...

For all they do for us, our hearts aren't very good at repairing themselves. So when a person suffers a heart attack, their blood pump is left with a large amount of scar tissue, which can impede the ...

A team of health and medical researchers affiliated with a host of institutions across Sweden has tested the possibility of reprogramming cancer cells into cDC1 cells as a means for destroying the ...

One promising strategy to remuscularize the injured heart is the direct cardiac reprogramming of heart fibroblast cells into cardiomyocytes. Researchers have identified TBX20 as the key missing ...

A new way of reprogramming our immune cells to shrink or kill off cancer cells has been shown to work in the otherwise hard to treat and devastating skin cancer, melanoma. The discovery demonstrates a ...
