The disclosed invention relates to the finding that the A2M-2 deletion mutation, which is a predisposing factor for Alzheimer's Disease, leads to the production of altered .alpha..sub.2 M RNA transcripts and proteins. Based on this finding, the invention provides for new therapeutic agents for AD, including molecules having A.beta. and low density lipoprotein receptor-related protein (LRP) binding domains, peptides, nucleic acid molecules, antisense oligonucleotides, and viral vectors for gene therapy. In addition, the invention relates to pharmaceutical compositions containing these therapeutic agents, methods of using these therapeutic agents to combat Alzheimer's Disease, and methods of screening for therapeutic agents that can combat Alzheimer's Disease.

A invenção divulgada relaciona-se a encontrar que o mutation do apagamento A2M-2, que é um fator predisposing para a doença de Alzheimer, conduz à produção de transcripts e de proteínas alterados do RNA do alpha..sub.2 M. Baseado neste encontrar, a invenção fornece para agentes therapeutic novos para o ANÚNCIO, including as moléculas que têm A.beta. e domínios obrigatórios receptor-relacionados da proteína do lipoprotein da densidade baixa (LRP), peptides, moléculas do ácido nucleic, oligonucleotides do antisense, e vetores viral para a terapia do gene. Além, a invenção relaciona-se às composições pharmaceutical que contêm estes agentes therapeutic, métodos de usar estes agentes therapeutic combater a doença de Alzheimer, e métodos de selecionar para os agentes therapeutic que podem combater a doença de Alzheimer.
