Tenure - deeply grateful to the students, postdocs, mentors, collaborators, and colleagues who made this possible. The next chapter will expand the lab towards a couple of new directions, including multiplexed interfacing with deep tissues and reengineering drug discovery.

Because my lab was located at a @nprcnews.bsky.social we had resources to move fast and within months Jerzy and Sin had redesigned a version of the RMA protein for IG1 Fc receptor in primates they called, NHP-RMAs. We injected the protein into the brain and O.M.G it worked inspiring this tweet.

We will be making a marmoset version soon fwiw, but the NHP version worked in mice, so I wouldn't be surprised if the macaque version worked in marmoset.

Monitoring gene expression in the brain with a simple blood test? In collaboration with @jerzyszablowski.bsky.social & his lab we figured out how to do it nonhuman primates using noninvasive neuroengineering of synthetic serum markers. nam11.safelinks.protection.outlook.com?url=https%3A...

How can serum marker tests be made more sensitive? The lab of @jerzyszablowski.bsky.social shows that editing markers in vivo to reduce their half-life can provide more sensitive measurement of gene expression dynamics. Read more: www.pnas.org/doi/10.1073/...

It does take a lot. The hope is that all the companies doing BBB permeable AAVs like Apertura, Capsida, Sangamo, Voyager etc. will find something that works 10-100-fold more efficiently.

Jerzy Szablowski @jerzyszablowski.bsky.social · 03/06/2025
Ultrasound BBB opening in large animals (or humans) is doable but somewhat complex. I do think the prices and complexity will go down over time for both gene delivery and BBB opening.

Jerzy Szablowski @jerzyszablowski.bsky.social · 03/06/2025
Doing whole brain BBB-permeable gene delivery + with FUS release of synthetic markers could allow to study multiple sites without surgery and monitoring intracellular gene expression. e.g. pubmed.ncbi.nlm.nih.gov/39110811/

That would be neat. Hong Chen at WUSTL has done some pioneering work in using FUS to release native proteins from the brain into the blood. There's non zero chance that native proteins carry sufficient information. If not, then the synthetic markers probably will, but would need gene delivery.

What do you want to study? I am always curious about what are the experimental hurdles people have. I am wondering if it site-specific liquid biopsy would be useful for you. It's much more technically complicated but can study different regions on different days.

Jerzy Szablowski @jerzyszablowski.bsky.social · 03/06/2025
There are some hurdles for human translation eg need for exogenous gene delivery. There are also ways to mitigate them. If our bright focus grant works out it should make translation realistic. There will be more work on optimization in nhps like higher signal, longer duration, recording c-fos etc

Thanks Mark. I think we were surprised it worked so robustly. Still lots of work to do, in mice we could do orders of magnitude signal and track c-fos, arc etc. Next paper, if we can get the funding. This was done on a shoestring.

qPCR can measure expression of virtually any gene... in homogenized tissues. Here, we show an "in-vivo qPCR" equivalent, where we measure a sequence-specific transcript with synthetic serum markers and enzyme-based signal amplification. www.biorxiv.org/content/10.1...
Schematic explaining In vivo tracking of active transcription. Injection of gene therapy is followed by measurement of the transcripts with RNA sensors, which produce a synthetic serum marker called RMA.
