Living cells say: Can you hear me now? (MIT)
It has long been known that cells release chemical signals in response to
outside conditions, triggering reactions inside the cell.
But it turns out that such communication is a two-way street: New research
shows that cells’ signaling mechanisms can tell whether their signals are
being received, and then adjust the volume of their messages as needed.
Cells use these chemical signaling systems to control many basic functions.
For example, signaling can control how genes are turned on and off in response
to external or internal cues, how cells grow and organize their internal
structures, and even how and when cells trigger their own death, a process
known as apoptosis.
The new finding could lead to new ways of finely controlling cells’ output of
signal molecules, which could be useful for everything from synthetic biology
to slowing the spread of cancer cells.
Researchers led by MIT’s Domitilla Del Vecchio, a Keck Career Development
Associate Professor in Biomedical Engineering, first proposed three years ago
that the signaling systems within cells might detect and respond to nearby
receptors for their signals. Their new research now presents the first direct
experimental evidence in support of this theory.
A paper on these results, …
