Researchers have identified a mechanism involving fatty acid metabolism that may determine whether a damaged cell enters ...

Researchers at Toho University have uncovered a previously unrecognized mechanism controlling how dying cells release the inflammatory cytokine IL-33, a key driver of allergy, asthma, tissue ...

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.

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, ...

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 ...

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 ...

Like a poison pen, dying cells prick their neighbors with a lethal message. This may worsen sepsis, Vijay Rathinam and colleagues in the UConn School of Medicine report in the Jan. 23 issue of Cell.
