Certain antibodies may be able to remove Alzheimer's plaques from the brain, according to new research carried about in mice. As much as 20 years before the symptoms of Alzheimer's set in, people with the disease begin to develop amyloid beta plaques that build up in the brain and, scientists believe, interfere with neural signals to cause cognitive and memory losses. But researchers at Washington University School of Medicine have developed an antibody that can remove the proteins these plaques are made of altogether, according to their new research. Several recent clinical trials have tried to use antibodies to target the plaques, but none have gotten past these trial phases, and many treatments have come with unsustainable side effects. The new approach may offer a way around these side effects and stop Alzheimer's plaques before its heart-breaking symptoms begin, the researchers hope.
