In many neurodegenerative diseases, proteins clump in the brain, forming so-called amyloid fibrils. Yet there exists a cellular defence mechanism that counteracts this process and even dissolves fibrils already formed. The mechanism is based on the activity of molecular helpers, so-called chaperones of the heat shock protein 70 family.

Even though repeated hits to the head are common in professional sports, the long-term effects of concussions are still poorly understood.

Researchers showed that na enzyme functions in genome maintenance by preventing double-stranded breaks in DNA during brain development in mice. In mice lacking this enzyme, these breaks occurred during epigenetic regulation of gene expression in the developing hippocampus, peaking two weeks after birth. The increased breaks were associated with abnormal neuronal dendrites and poor memory ability.
