In certain contexts, the Notch receptor may participate in “reverse signaling,” influencing neighboring cells directly.

In a groundbreaking study on the synthesis of cellulose -- a major constituent of all plant cell walls -- a team has captured images of the microscopic process of cell-wall building continuously over ...

Microtubules perform an active role in communication within the cell by transmitting received signals to the cell's functional units. Researchers at the Paul Scherrer Institute PSI and the Department ...

(MEMPHIS, Tenn. – November 6, 2025) The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme’s “tail” called phosphorylation patterns.

Dead cells after the self-destruction and fragmentation process. The large green areas are the “eat me” signals which alert immune cells to kick-start clean-up and recycling process, while the small ...

Cell walls are a crucial structure of plant life, protecting cells from damage, giving plants shape, and containing ...

Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...

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 ...
