Cracking open the black box of autoimmune disease
...as a kind of military unit, a defense network that guards
the body from invaders. Seen in this way, a group of white blood cells called T cells are the frontline soldiers of immune defense, engaging invading pathogens head on. These T cells are commanded by a second group of cells called regulatory T cel...
Scientists uncover critical step in DNA mutation
...," said Landman. "Perhaps such inherent complexity guards
us from harmful mutagenetic events occurring more frequently, and it is possible that similar principles may hold in other important processes of biological relevance." "This type of research requires the development of new modeling strategies and ...
