U.S. researchers have developed a way to harness the immune system to test for Alzheimer's, an approach they say could lead to a blood test for the disease within months.
A study of the technology showed it accurately spotted Alzheimer's in blood samples from six people with the disease, Thomas Kodadek of the Scripps Research Institute in Jupiter, Florida, wrote Thursday in the journal Cell. The approach may work in other diseases, like cancer, Kodadek said in a telephone interview. The test looks for antibodies, or immune-system proteins, that help the body attack foreign invaders.
Antibodies fight off infections but Kodadek said researchers are beginning to think that most diseases cause changes in cells that make the body see the cells as foreign invaders. He believes the body may produce antibodies in response to a range of diseases and would like to develop blood tests that look for them.
His team used laboratory-made molecules called peptoids as antigen surrogates to screen for antibodies specific to Alzheimer's disease. Read more: msnbc.msn.com
