Monday, October 14, 2002They said the antibodies recognized AB in tangles, diffuse AB deposits and AB in blood vessels of the brain and were able to cross the blood-brain barrier, which suggests they might have the capacity to directly destroy plaques in the brain. The antibodies did not, however, attack the longer form of AB that occurs in the nerve cells of healthy people as well as Alzheimer's patients. The function of that type of AB is unknown, but healthy nerve cells can contain a lot of it. This selectivity is good news, because an attack on the longer form of AB could potentially result in complications. If healthy nerve cells contain a lot of it, then I'll keep mine, thank you, and not risk it to a vaccine. posted by Sydney on 10/14/2002 08:02:00 AM 0 comments 0 Comments: |
