Their study, Dr. Chesebro says, indicates that prion diseases can be divided into two groups: those with plaques that destroy brain blood vessels and those without plaques that lead to the sponge-like damage to nerve cells. Dr. Chesebro says the presence or absence of the prion protein anchor appears to determine which form of disease develops.

The new mouse model used in the study and the two new human GSS cases, which also lack the usual prion protein cell anchor, are the first to show that in prion diseases, the plaque-associated damage to blood vessels can occur without the sponge-like damage to the brain. If scientists can find an inhibitor for the new form of prion disease, they might be able to use the same inhibitor to treat similar types of damage in Alzheimer's disease, Dr. Chesebro says.
