(WikiDoc) - Scientists looking at prenatal brain development have come up with a novel theory on how Alzheimer's kills brain cells. According to research published in Nature, a chemical mechanism that "prunes" unwanted cells in early brain development may get hijacked late in life, putting the brain in a kind of self-destruct mode. A key protein behind the pruning process, APP, is known to play a role in Alzheimer's, though researchers have been unsure how it works exactly. The researchers plan on trying to disrupt the mechanism in adult brains, and seeing if that halts the progression of the disease.
