USE A FRAGMENT АВ FOR TREATMENT OF ALZHEIMER'S DISEASE

摘要

The invention provides methods useful for effecting prophylaxis or treatment of Alzheimer's disease. Such methods entail administering A-beta fragments from a central or C-terminal regions of A-beta. Such fragments can induce a polyclonal mixture of antibodies that specifically bind to soluble A-beta without binding to plaques. The antibodies can inhibit formation of amyloid deposits of A-beta in the brain of a patient from solublethus preventing or treating the disease. Fragment A-beta 15-24 and subfragments of 5-10 contiguous amino acids thereof are preferred immunogens due to their capacity to generate a high titer of antibodies.
