What will help to stop cell death? The idea is to prevent the agglutination of the amyloid, or Tau, protein from occurring in the first place. There are already chemicals that should reduce the agglutination of the Tau protein: one of them is methylene blue. In the test tube it has already been proved that the substance can prevent Tau agglutinations. The researchers first have to find out whether this also works in an animal model: Both the healthy fishes and the Tau fishes are treated with different concentrations of methylene blue. Can this be used to reduce the number of dead cells?
