Apoptosis is a highly regulated form of programmed cell death essential for embryonic development, tissue homeostasis and elimination of damaged or infected cells. Two principal signalling cascades ...

"Our results demonstrate that the microalga Guillardia theta experiences apoptotic cell death in physiological conditions, similar to animal cells. Since these algae already existed prior to the ...

After cells die, they leave a residue that sends messages to other cells in ways that are valuable to the immune system. But this process can also be hijacked by viruses such as influenza, according ...

When cells are about to die, they send signals that trigger proteins which are supposed to destroy them, but it doesn’t always happen that way. Some cells activate the signal but then resist the ...

Apoptosis, or programmed cell death, is a tightly regulated biological process necessary for normal tissue maintenance and development. However, aberrations in apoptotic signaling networks are ...

In every organism, the regulation of cell populations is a constant process. This balance relies on a continuous interplay between "guardian" proteins that promote cell survival and "killer" proteins ...

New research has uncovered a hidden pathway that allows COVID-19 to infect the immune system and trigger damaging inflammation in the lungs. The study by La Trobe University and WEHI researchers found ...

Newborn mice experienced apoptotic cell death after exposure to the anesthetic agent isoflurane, according to a study published in Anesthesia-Analgesia. Researchers from the University of Cincinnati’s ...

Unlike accidental cell death, some cells can actively decide to die through a controlled process. This is called programmed cell death and can occur in different forms, including apoptosis and ...

Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, ...

Here’s what you’ll learn when you read this story: When cells are about to die, they send signals that trigger proteins which are supposed to destroy them, but it doesn’t always happen that way. Some ...
