Until recently, scientists knew these diseases were triggered by a problem with mitochondrial fusion, but didn't understand fusion itself, says Jodi Nunnari, a UC Davis professor of molecular and cellular biology.

...susceptible to prion diseases, they do assume what scientists call the yeast prion state. Two protein domains called NM together form self-propagating amyloid fibers that give rise to the yeast prion state. Oligomers, which are typically seen when other proteins form amyloids, have also been seen during this pr...Amyloid fibers sprout one step at a time
... Drawing on expertise in the Vale laboratory, the scientists complemented these indirect studies with "single-molecule fluorescence technology" to observe fiber growth directly. In this technique, an immobilized fiber is first tagged with one fluorescent molecule. When shorter amyloid segments or monomers are ...Genes expose secrets of sex on the side
