An international research team has discovered a previously unknown mechanism that plays a key role in the signaling pathways ...

Death ends the body’s ability to function as a whole, but it does not kill every cell at the same instant. Research has shown that some human cells remain viable for hours or even days after death, ...

This suggests that immune cells may intentionally access nuclear DNA from dying cells as part of regulated immune signaling processes. Such extracted nuclear DNA could act as molecular messengers, ...

Given the right conditions, certain types of cells are able to self-assemble into new lifeforms after the organism they were ...

During transplantation, blood flow to the donor liver must stop as it's moved to the recipient. Once transplanted, oxygen-rich blood is restored, yet doing so can cause what is called ...

A new study from Ben-Gurion University of the Negev (BGU) has identified a molecular switch that controls whether stressed ...

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 ...

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.

Scientists discovered a population of cells that can start the process of programmed cell death, survive it, and then help rapidly rebuild damaged tissue. Their descendants become far more resistant ...

The thymus is essential for producing the T cells that protect us from infections and cancer. But this organ is also highly sensitive to damage. Treatments like chemotherapy, radiation, and ...

IL-33 is primarily released through NINJ1-mediated membrane rupture, whereas the timing of NINJ1 activation induced by Gasdermins and other factors differs between individual cells. Researchers at ...
