BRIT1 allows DNA repair teams access to damaged sites
Like a mechanic popping the hood of a car to get at a faulty engine, a tumor-suppressing protein allows cellular repair mechanisms to pounce on damaged DNA by overcoming a barrier to DNA access.

For decades, microbiologists assumed that macrophages, immune cells that can engulf and poison bacteria and other pathogens, killed microbes by damaging their DNA. A new study from the University of Illinois disproves that.

When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis.
