Insights on nutrient traffic in living cells

September 22, 2005 

In a new study that may have important applications in medicine, researchers from the University of California Santa Barbara found that cells have evolved a surprising, but efficient, way to regulate the transport of goods to the nucleus and surrounding organelles. 
Nutrients and signals outside of a cell get to the cell nucleus by way of carriers called endosomes. Endosomes travel through a cell on a highway of structural supports called microtubules. 
Researchers studied the motion of endosomes by putting florescent tags, which glow under certain types of light, on individual endosomes and recording their motion through a microscope. They found that endosomes do not travel straight to the nucleus. Instead, they randomly travel toward and away from the nucleus with no preferred direction.
