TAF15 amyloids propagate via defined motifs in a prion-like fashion
TATA-box binding protein-associated factor 15 (TAF15) is an RNA-binding member of the FET family recently identified as the primary fibrillar constituent in a subset of frontotemporal lobar degenerati...

🚨Thrilled our work is out in @NatureComm!🚨 Energetic profiling of >110 cryo-EM amyloid fibrils (IAPP, tau, α-syn) reveals how APRs + cofactors shape fibril maturation and disease-relevant polymorphs. Read the full paper: doi.org/10.1038/s414...

Energetic profiling reveals thermodynamic principles underlying amyloid fibril maturation - Nature Communications
Energetic profiling of cryo-EM time series for IAPP, tau, and α-synuclein reveals how amyloid fibril maturation is driven by sequence-encoded hotspots. Rearrangement of APRs anchors growth, while cofa...

🚨New Preprint Alert🚨 Collaborative effort from my post‑doc days at @vib-switch-lab.bsky.social, so many brilliant colleagues came together to show how medin steers Aβ40 toward Aβ42‑like fibril polymorphs. Grateful to have played a part! www.biorxiv.org/content/10.1... #amyloid #Alzheimers

Medin drives Aβ40 to adopt Aβ42-like fibril polymorphs in vitro
Medin, a vascular amyloid derived from MFG-E8, is the most prevalent form of localized human amyloid and co-localizes with Aβ in Alzheimer’s disease and, in particular, cerebral amyloid angiopathy (CA...

🚨New lab preprint!🚨 Thermodynamic profiling of cryoEM fibrils shows that key stabilizing motifs shuffle during amyloid maturation, while cofactors ease structural frustration to let energetically optimal polymorphs emerge. www.biorxiv.org/content/10.1...

Energetic profiling reveals thermodynamic principles underlying amyloid fibril maturation
Amyloid fibrils adopt diverse structural polymorphs that underlie disease-specific phenotypes, but the thermodynamic principles guiding their formation and maturation remain poorly understood. Here, w...
