Gene vaccine for Alzheimer's disease shows promising results
... T cells. When we get to human studies, we hope to show
that humans can make human antibodies against the amyloid as well." Current treatments for Alzheimer's disease focus on the symptoms since no therapies have been clinically proven to slow or prevent progression of the disease. Amyloid protein deposi...
