CHICAGO (CBS) -- Lysosomes – membrane-bound structures within each cell of humans and all animals – are sometimes known as the cells' "garbage disposals" or "cellular janitors." The structures are ...

Lysosomes are membrane-bound organelles in cells that act as recycling centers—breaking down waste materials, damaged organelles, and unwanted molecules using powerful digestive enzymes. Lysosomes ...

Fukuoka, Japan—The duplication and division of cells is critical to keeping all multicellular organisms alive. But the opposite process is equally important: cell death. Controlled death of cells, or ...

The duplication and division of cells is critical to keeping all multicellular organisms alive. But the opposite process is equally important: cell death. Controlled death of cells, or programmed cell ...

New research, published today in the journal Science, shows how lysosomes - organelles that act like cells' waste disposal system - respond to stress by becoming abnormally bloated, a process called ...

The rap sheet for β-CTF is growing longer. The C-terminal fragment, produced when β-secretase cleaves APP, binds to—and blocks assembly of—vacuolar ATPase, a proton pump that fuels acidification of ...

Macrophages rely on lysosomes to balance microbial killing with self-protection, generating reactive oxygen and nitrogen species during phagocytosis. Using platinum nanoelectrodes, researchers at ...
