Abstract: "The neutral and phospholipid composition of mouse brain infected with scrapie prions was investigated. During the later stages of this disease, the level of dolichol decreased by 30% whereas the level of dolichyl phosphate increased by 30%." P.283 left column 3rd paragraph: "The dolichol content of brain increases continuously during the whole lifetime of the mouse, but this increase occurred to a much lesser extent in scrapie-infected animals. In the final stage of the disease process, the difference in the dolichol contents of brains from infected and uninfected animals was as much as 30%. Decreased dolichol concentrations have also been found in the brains of patients with Alzheimer’s disease (Soderberg et al., 1992). In model membranes, dolichol has a destabilizing effect and increases both the membrane fluidity and permeability (de Ropp and Troy, 1985, Valtersson et al., 1985)." |
