A timeline of tau-mediated synaptotoxicity Oligomeric tau has been increasingly implicated in synaptic impairments observed in Alzheimer’s disease. In a recent study, Pareja-Navarro and colleagues provide insights into the precise timeline of ...

Really happy to share a new article that myself and the wonderful @clairedurrant1.bsky.social have authored, discussing recent work which demonstrates a timeline of dysfunction at the synapse in response to oligomeric tau. See the Trends in Neuroscience Spotlight article 👉 lnkd.in/edH2y3FThttp...

FMRP regulates adult human cortical excitability via cyclic-AMP signalling Fragile X Syndrome (FXS) is a common inherited neurodevelopmental condition, resulting from loss of Fragile X Messenger Ribonuclear Protein (FMRP). Rodent models of FXS display cellular hyperexcitabil...

super excited to release this. nearly 7 years ago, we set out to investigate whether FMRP regulates excitability of neurons in living human brain tissue. we find loss of FMRP in adult neurons leads to elevated excitability, corrected by PDE4D inhibition.

Evidence for trans-synaptic propagation of oligomeric tau in human progressive supranuclear palsy - Nature Neuroscience McGeachan et al. observe oligomeric tau in synapses from individuals with progressive supranuclear palsy and provide evidence that tau pathology may spread through the brain via synapses.

'People think my wife is drunk but she's living with a rare brain disease' Edinburgh couple hope for treatment for rare neurological condition progressive supranuclear palsy.

See a lovely piece on STV highlighting the impacts of this disease on families . While our new findings will not lead to a new treatment today, we aim to bring hope to people living with PSP for the future news.stv.tv/east-central...

Delighted to share our paper examining synaptic tau in PSP. Many thanks to @robertmcgeachan.bsky.social @clairedurrant1.bsky.social and our many collaborators and funders. And extra special thanks to tissue donors who make this work possible.

Living human brain tissue used to mimic Alzheimer’s in breakthrough study Exclusive: British team exposed live cells to toxic proteins to gather rare insight into how dementia develops Scientists have used living human brain tissue to mimic the early stages of Alzheimer’s disease, the most common form of dementia, in a breakthrough that will accelerate the hunt for a cure. In a world first, a British team successfully exposed healthy brain tissue from living NHS patients to a toxic form of a protein linked to Alzheimer’s – taken from patients who died from the disease – to show how it damages connections between brain cells in real time.

Divergent actions of physiological and pathological amyloid-β on synapses in live human brain slice cultures - Nature Communications Understanding synapse loss in Alzheimer’s disease has been hampered by a lack of human model systems. Here, the authors show that manipulation of physiological or pathological Aβ has differing effects...

Fantastic to see this work from @clairedurrant1.bsky.social group out in print! Important results using living human brain tissue to study Alzheimer’s disease www.nature.com/articles/s41...

It was a pleasure to visit St Andrews to deliver a TEDx talk! www.youtube.com/watch?v=hJME...

@bonthronphd.bsky.social highlighted the importance of industrial collaborations to work towards a cure, as well as showing off our lovely microscopes!

Amazing to welcome HRH The Duchess of Edinburgh, Patron of Race Against Dementia to our lab! An incredible opportunity to showcase our work with living human brain slice cultures and the importance of investing in dementia research. We are very lucky to have her support.

Guests from Alzheimer Scotland recently visited our labs, sharing their inspiring personal stories, the impact of diagnoses on their lives as well as the advocacy work they do for those living with dementia and their families. A reminder of why we do what we do. 🧠🔬🧫https://tinyurl.com/97z8ha9v
