Prion proteins play powerful role in survival, evolution of wild yeast strains
Prions, the much-maligned proteins most commonly known for causing "mad cow" disease, are commonly used in yeast to produce beneficial traits in the wild. Moreover, such traits can be passed on to subsequent generations and ...

Cellular stress can induce yeast to promote prion formation
It's a chicken and egg question. Where do the infectious protein particles called prions come from? Essentially clumps of misfolded proteins, prions cause neurodegenerative disorders, such as mad cow/Creutzfeld-Jakob disease, ...

Size of protein aggregates, not abundance, drives spread of prion-based disease
Mad Cow disease and its human variant Creutzfeldt-Jakob disease, which are incurable and fatal, have been on a welcome hiatus from the news for years, but because mammals remain as vulnerable as ever to infectious diseases ...
