A study published in Nature Neuroscience demonstrates that the excess of glucose chains (glycogen) induces neuronal death and causes Lafora disease, a fatal kind of epilepsy that affects adolescents. This mechanism, unknown until now, may provide the key to understanding other neurodegenerative pathologies.

<p>After entering the egg, the centrosome (red) associated with the paternal nucleus (upper blue circle) organizes a microtubule network (green) that facilitates its fusion with the maternal nucleus (lower blue circle). Asterless is one of the proteins requi</p>

This finding shows that centrosomes, organelles inside the cell responsible for organizing the microtubule network, are required for the correct development of an organism.
