ABSTRACT:
In vivo assays for selecting candidate therapeutics for inhibiting amyloidoses, such as congophilic and fibrillar .beta./A4 amyloid deposition in brain. A candidate reagent is administered to a first rat in a first infusate comprising .beta./A4 peptide and perlecan by continuous infusion into the hippocampus for at least one week. The candidate reagent is selected as a candidate therapeutic for inhibiting congophilic and fibrillar .beta./A4 amyloid deposition in brain if the first infusate diminishes congo red and thioflavin S staining indicative of amyloid deposition adjacent to the infusion site, as compared with a second rat receiving a second infusate consisting essentially of .beta./A4 peptide and perlecan.
