The cell's endoplasmic reticulum (ER) plays a central role in protein synthesis, folding, and calcium (Ca²⁺) storage. When ...

A collaborative French–Swiss study reveals a previously unknown role for astrocytes in the brain's information processing. Published in the journal Cell, the research shows that these glial cells are ...

Janelia researchers have uncovered a novel way that two of the structures inside cells-the endoplasmic reticulum (ER) and lysosomes-coordinate the production of proteins, highlighting how interactions ...

The body's cells change their shape to close gaps such as wounds – with part of the cell flexing depending on the curve of the gap and the organization of cell-internal structures, a new study reveals ...

A team of researchers at the University of Colorado has found that the endoplasmic reticulum (ER) makes contact with at least two membraneless compartments in cells and influences their behavior. In ...

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of ...

When cells experience enough chronic stress, they can stop dividing permanently. In this state of cellular limbo, known as ...

Within aging organisms, cells slowly lose their youthful precision: Membranes stiffen, repair systems malfunction, and proteins begin to misfold and pile up. One of the cell organelles that ...
