HAPPY PRIDE 🏳️‍🌈

Under Trump, research using terms like “Trans,” “LGBTQ,” & “Gender identity” is being defunded. These terms reflect real people who deserve science that includes them.

Stand with us to protect LGBTQ+ science from political erasure.

A word cloud made from flagged terms in terminated NIH grant proposals. The most prominent words in large font include “trans,” “diverse,” “diversity,” “minority,” “sex,” “expression,” “mental health,” “gender,” and “women.” Other visible terms include “LGBTQ,” “racial,” “underrepresented,” “disability,” “barriers,” “black,” “equity,” “health equity,” “vaccine,” “bias,” and “intersectionality.” The word cloud highlights terms related to identity, inclusion, and marginalized communities.

How does APOE change your risk of developing Alzheimer's disease? At least partially by changing the function of immune cells in your brain 🧠🧬

💭 Our PhD & Postdoc reps initiated visits to our Technology Hubs for our researchers and kicked off with a visit to our Single-Cell and Spatial Transcriptome Hubs last week.

👋 Thanks Arek Kendirli, Janos Groh, Clara de la Rosa del Val, and Simon Frerich for hosting the first event of the series!

We've been studying mechanisms of resilience that protect lysosomes from damage and wrote a review on the topic. We consider lysosomal stress and damage on a spectrum. Please help me share as this is my first post 😀 and I don't have many followers! 🙏 Open Access: www.embopress.org/doi/full/10....

Excited to share our latest work with Denali Therapeutics as Deep Piction. Using our proprietary clearing & imaging, we’ve mapped the full targeting profile of brain-penetrating transport vehicles (ATVs) in both whole mouse bodies and monkey brains. nature.com/articles/s41...

We did it and now it is published: A highly Lewy-fold selective and quantitative Synuclein Aggregate Amplification Assay (SAA). Huge thanks to the amazing teams at MODAG GmbH, LMU Munich, and Bologna University!

This is really interesting. Known for a long time lysosomal enzymes are secreted- it’s the principle of cross correction for lysosomal
Storage diseases. However the idea lysosomes are released or degrading plaques extracellularly is 🤯. Do they differ from EVs/EPs?

Microglia degrade Alzheimer’s amyloid-beta deposits extracellularly via digestive exophagy
Jacquet et al. shows that microglia use digestive exophagy to engage large Aβ deposits that cannot be phagocytosed, forming acidic extracellular compartments on the aggregates into which lysosomal enz...

Very happy to announce that the PaquetLab is now on Bluesky. We are excited to connect with everyone interested in our research and present updates on our work and lab activities! Our lab engineers 3-dimensional models of #human-brain-tissue and the #BBB and applies them to investigate ...

In summary, we show that a novel therapeutic approach of single-dose peripheral AAV-induced delivery of a brain penetrant biotherapeutic molecule, can replace PGRN protein levels in the brain and ameliorate disease-relevant phenotypes! (8/8)
haasslab.bsky.social
What about a human model system? To assess this we also created a novel human TMEM106B/GRN DKO iPSC model that recapitulates TDP-43 pathology, neurodegeneration and lysosomal abnormalities – all phenotypes can be rescued by treatment with PTV:PGRN (7/8)

Increased PGRN levels lead to a reduction of TDP-43 pathology, decreased neurodegeneration and an amelioration of motor deficits and behavioural phenotypes! (6/8)

Applying AAV(L):bPGRN to Tmem106b x Grn double KO mice, we show that a single injection can restore progranulin levels in neurons, microglia, astrocytes and endothelial cells for a prolonged time (5/8)

In this study, we use a novel therapeutic approach, combining protein replacement with gene therapy. We exploit a liver-transducible AAV (AAV(L)), which induces brain penetrant (b)PGRN expression in hepatocytes and releases it to the blood to be transcytosed into the brain (4/8)
