Portrait: Stockholm University
Büttner came up through the Graz school of yeast cell death, and her own laboratory now asks a question one level up from a single pathway: how do organelles inside one cell stay coordinated, and what happens to protein homeostasis and cellular fitness when that coordination degrades with age.
In this corpus she appears on both spermidine papers. EIS2009 established that the polyamine induces autophagy and extends lifespan in yeast, flies, worms and human immune cells; EIS2016 carried it into mice and made the cardiac protection depend on Atg5. Her presence on both is one reason the Atlas can treat them as one line of evidence rather than two unrelated results.
She is also a co-author of the yeast cell death nomenclature guidelines, which is the kind of work that keeps a field's terms usable — the same reason this Atlas is careful about what counts as autophagy and what counts only as autophagosome number.
