ELLPs

Caption

This microscope image shows extremely long-lived proteins, or ELLPs, glowing green on the outside of the nucleus of a rat brain cell. DNA inside the nucleus is pictured in blue. The Salk scientists discovered that the ELLPs, which form channels through the wall of the nucleus, lasted for more than a year without being replaced. Deterioration of these proteins may allow toxins to enter the nucleus, resulting in cellular aging.
