Cells that are about to die send a signal to an executioner protein, but sometimes, those cells can fight back and regenerate, becoming essentially a zombie cell.

Scientists at Nagoya University in Japan studied what happens when macrophages—a type of immune cell—encounter dying cancer cells in tumors and discovered a mechanism that accelerates tumor growth.

Even in death, cells leave a trace. Scientists have discovered a microscopic “Footprint of Death” that not only helps the immune system clean up but can also give viruses a new way to spread infection ...

Billions of cells die in your body every day. Some go out with a bang, others with a whimper. They can die by accident if they’re injured or infected. Alternatively, should they outlive their natural ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

The process of necrosis, a form of cell death, may represent one of the most promising ways to change the course of human aging, disease and even space travel, according to a new study. The process of ...

In Alzheimer's, brain cells die too soon. In cancer, dangerous cells don't die soon enough. That's because both diseases alter the way cells decide when to end their lives, a process called programmed ...

A study by the team of Prof. Kodi Ravichandran (VIB-UGent Center for Inflammation Research) and colleagues found that pyroptosis, a form of programmed cell death traditionally thought to be purely ...

BUFFALO, N.Y. — When the myelin sheath that surrounds nerve fibers in the brain and spinal cord becomes damaged, a number of debilitating conditions can result that limit mobility, inhibit ...

Some go gently into the night. Others die less prettily in freak accidents or deadly invasions, or after a showy display. By Amber Dance/Knowable Magazine Published Sep 27, 2024 8:00 AM EDT This ...
