In a new preprint from my lab @LeibnizFLI we found that polyamines sustain the regeneration of the intestinal epithelium in old mice 👇biorxiv.org/content/10.1101/…

Our paper introduces membrane-impermeable caspase inhibitors that use GSDMD pores as their entry route.
Because these compounds can't cross an intact membrane, they enter only cells already forming GSDMD pores — before pore density exceeds the cell's repair capacity. This confers built-in specificity: the drug acts solely on pyroptotic cells, leaving apoptosis and healthy cells untouched, addressing the off-target toxicity that has limited earlier, cell-permeable caspase inhibitors.
The effect goes beyond arresting cell death. Cells already committed to pyroptosis reverse course and regain viability — a "Lazarus effect" that challenges the assumption that lytic cell death, once initiated, is irreversible.
In essence, these unexpected results could create new opportunities for precisely targeting inflammatory cell death while safeguarding healthy tissue.

My lab is moving to Stanford, and we’re looking for an RA and a Postdoc to join us.
The position will focus on ovarian and brain aging in flies. If you’re excited about genetics, aging, and discovery, we’d love to hear from you.

🔥Out now in @CellCellPress from the amazing @QiushuangW & co: dietary arginine shapes anti-viral & anti-tumor immunity, repressing MHC-I translation in a codon-usage–dependent way—impairing defense against flu, SARS-CoV-2 & colon cancer. 🧵👇 cell.com/cell/abstract/S0092…
1/9. Very happy to share that my postdoctoral work is now out in @CellCellPress . Dietary arginine drives codon-dependent MHC class I translation and improves immunity in colon tumorigenesis and respiratory viral infection: Cell cell.com/cell/fulltext/S0092…

Protein synthesis is not equally accurate across organs.
Excited to share our new preprint:
biorxiv.org/content/10.64898…
We developed a new mouse model to quantitatively monitor translation errors and uncovered the spatiotemporal dynamics of the “quality” of protein synthesis.

Our Brain LysoAtlas is now out in Cell!
We map the cell-type-specific protein composition of lysosomes and link SLC45A1 to neurological disease.

New exciting work from Jae Ho Lee in our lab, in a fantastic collaboration with Alessandro Ori @AOri_lab and Alessandro Cellerino @Alessan82703458 on why and how the brain ages and becomes vulnerable to neurodegenerative diseases science.org/doi/10.1126/scie…

Excited to share a milestone published in @NatureMedicine from our decade-long effort to build The Human Phenotype Project, a unique longitudinal cohort with unmatched depth of clinical and multi-omic profiling, enabling truly predictive, personalized medicine.
Led together with @ericxing, it is a global collaboration between @WeizmannScience, @MBZUAI, and Japanese partners, spanning 30,000+ participants and continuing to grow internationally
By devising AI models trained on individuals deeply profiled with genetics, microbiome, glucose, sleep, bone density, and more, we can now forecast diseases before symptoms appear and simulate treatment or lifestyle outcomes.
Key findings:
• Re-defined metabolic risk thresholds
• Predicted menopause impact via biological aging
• Mapped organ-specific aging trajectories
• Developed models for early detection of diabetes & heart disease
This dataset is a blueprint for digital health twins, AI-driven tools grounded in real-world, longitudinal data

Our new paper from the @FrydmanLab published in @ScienceMagazine identifies 22 TRiC mutations in patients with brain disorders of unknown origin. We characterized these disease-linked mutations in 3 model species and found them to be dominant mutations.

I am thrilled to announce that our work in collaboration with Alessandro Ori’s lab @AOri_lab, @Blue_ceil is out!
We made a significant breakthrough in understanding the role of lysosomes in the brain with the development of the first cell-type-resolved lysosomal protein atlas. This comprehensive map details the lysosomal proteome across major brain cell types—neurons, astrocytes, microglia, and oligodendrocytes.
