4. In hereditary forms of prion diseases, a genetic change (a mutation represented by the red dot) in one of the two genes encoding PrPc, may result in a slightly altered structure of the PrPc-protein. The mutation makes it easier for PrPc to change its conformation into PrPSc, initating a chain reaction that will result in the accumulation of a large number of PrPSc molecules. The filamentous aggregates that are gradually formed may contain both altered normal (unmutated) and mutated PrPSc.
Nobel Prizes and laureates
Six prizes were awarded for achievements that have conferred the greatest benefit to humankind. The 12 laureates' work and discoveries range from proteins' structures and machine learning to fighting for a world free of nuclear weapons.
