Together, we describe two compensatory secretion pathways that could be important to delay neurodegeneration. However, prolonged upregulation of these pathways could contribute to neuroinflammation.

Additionally, we show the release of exosomes is upregulated and that this release is critical to stave off apoptosis

We find that the secretion of LC3+ autophagic membrane extracellular vesicles (SLAM-EVs) is upregulated in neurons harboring a Parkinson's disease causing mutation

SLAM-EVs contain known autophagic cargos including mitochondria and synaptic proteins

Very excited to share my postdoc work- out now at PNAS!

Learn more about how neurons facing chronic autophagic stress compensate by upregulating two secretion pathways

This is going to hurt science. 🧪

Call, email, and if possible visit, your representatives. This is personal whether you want it to be or not.

This morning, the US National Science Foundation fired 168 employees, approximately 10% of its workforce, for no cause other than they were the agency's most recent hires. 🧪

Co-workers are leaving supportive messages before they have to clear out of the building at 5 p.m. Sent to me by a source ⬇️
Handwritten notes on a metal table at the National Science Foundation, 2/18/25. The messages include "You deserve better! Thank you!"; "Thank you colleagues! This RIF is WRONG. These orders are immoral & illegal"; and "Your service will forever be remembered and deeply valued - ENG directorate".

Very good source to understand indirect costs by Sally Rockey, former Deputy Director for Extramural Activities at NIH.

Very thorough and clear.

If you want to understand indirect costs or have family or friends who are pestering you to explain IDC, send them this...

⚠️ Effective Monday 2/10/25, NIH indirect rate capped at 15%. Applies to existing & future grants.

—> Deep budget cuts & program closures coming to a university near you.

Is this the break the glass moment for university administrators who have been silent so far about the attack on science?

Shout out to Dr. Bishal Basak in @erikaholzbaur.bsky.social at @upenn.bsky.social for spearheading the work on identifying a new stress response pathway that regulates mitophagy in neurons!

🎉 We are celebrating Bishal Basak from CRN Team Hurley as our January #NetworkSpotlight. Bishal worked on a Team paper where he identified a novel, neuron-specific mitophagy pathway. Thank you, Bishal!

If you’re a federal govt employee targeted for leave or termination on the basis of your DEI work, please file an EEO (Equal Employment Opportunity) complaint & retain legal counsel.

I’m a former NIH PI. Happy to refer you to a law firm that has successfully sued the govt many times!

Pls repost 🙏❤️

I just reached out to my senators about the NIH situation. If you need to find out how much impact NIH has in your state in terms of dollars in and their economic impact here's a link: www.unitedformedicalresearch.org/nih-in-your-...

Step 1) find your rep

www.congress.gov/members/find...

Step 2) send an email or call their office

Step 3) tell them that federal spending on scientific advancement is the best hope we have to “win against china” or whatever these guys are obsessed with these days

Study sections are the review panels that allocate NIH research grants. They bring in experts from around the country and have to be scheduled many months in advance; they provide the funds that keep the nation's biomedical research going.

It's hard to overstate the disruption this causes.

All NIH study sections canceled indefinitely. This will halt science and devastate research budgets in universities.

The United States built a publicly funded scientific enterprise that worked miracles. We went to the moon and mars, laid the groundwork for computing revolutions, turned AIDS from a death sentence to a chronic condition, drastically cut cancer deaths. And now we're just going to dismantle it?
