Nice paper from colleagues emphasising prion-like mechanisms in dementia and inclusion of CJD in funding mechanisms for dementia disorders. Surprising resistance to prion-like mechanisms in dementia communities which imo often stems from poor understanding https://t.co/Yt9YCTHsnz
Perhaps the most important take home message from her work is that there is intrinsic structural variability between individual preparations of α-synuclein PFFs generated under identical conditions, which needs to be accounted for when designing and interpreting experiments.
Online now in Neuron, the final published version of @xsakuraphie's PhD work on α-synuclein strain generation:
Stochastic misfolding drives the emergence of distinct α-synuclein strains: Neuron https://t.co/SvxrzsKyOZ
One of Raphie's most interesting findings was that α-synuclein PFFs that mimic the seeding behavior of Parkinson's disease brain extract can be generated in vitro, but we only obtained the specific "PD-like" PFF polymorph once from 35 independent PFF preparations.
Genki's results support a model in which P4HB helps to stabilizes PrPC levels but also directly enhances the conversion of PrPC into PrPSc.
Although much work remains to be done, targeting P4HB may constitute a new strategy for modulating prion replication.
I'm pleased to announce that our latest prion-related work is now available as a preprint:

Dr. Genki Amano looked at whether P4HB, a protein disufide isomerase often identified in PrPC interactome screens, affects PrPC biosynthesis and prion replication.
A huge congratulations to Dr. Raphaella So (@xsakuraphie) on a wildly successful PhD defense today. Also, a big thanks to @lvolpic for serving as the external examiner.
Congratulations to all involved in this study (including @speedyerica), and a special thanks to Benedikt Frieg and José Camino for performing the cryo-EM experiments.
It is my great pleasure to share our most recent work on α-synuclein strains: https://t.co/4EwLAS39OK. This study was led by @xsakuraphie and represents an amazing collaboration with Gunnar Schröder's lab.
Furthermore, our work reveals that stochastic misfolding results in considerable prep-to-prep variability among PFFs, which can influence downstream phenotypes. Thus, the inherent variability of α-synuclein PFFs needs to be accounted for when designing/interpreting experiments.
Lab field trip!
It’s rare to have so many lab members at a conference together (since we usually travel in packs of 2-3, max)
Thanks TRIDENT for having us :) Excited to be learning here in the beautiful town of London, ON

Today is #CJDAwarenessDay. #Prions cause devastating neurological diseases such as CJD in humans. No cures are available, but promising research recently presented at the #Prion2024 conference.
