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...

πŸš€ Our new preprint is out!
We uncover that TAF15 forms amyloids that propagate in a prion-like manner via defined APR motifs.

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

🚨Thrilled our work is out in @NatureComm!🚨

Energetic profiling of >110 cryo-EM amyloid fibrils (IAPP, tau, Ξ±-syn) reveals how APRs + cofactors shape fibril maturation and disease-relevant polymorphs.

Medin drives AΞ²40 to adopt AΞ²42-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 AΞ² in Alzheimer’s disease and, in particular, cerebral amyloid angiopathy (CA...

🚨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 AΞ²40 toward AΞ²42‑like fibril polymorphs. Grateful to have played a part!

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...

🚨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.
