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.

🔥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.

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 Data access: humanphenotypeproject.org Full paper: tinyurl.com/4kftyndh Thanks to all the people who led this work: Lee Reicher, Smadar Shilo, Anastasia Godneva, Guy Lutsker, Liron Zahavi, Saar Shoer, David Krongauz, Michal Rein, Sarah Kohn, Tomer Segev, Yishay Schlesinger, Daniel Barak, Zachary Levine, Ayya Keshet, Rotem Shaulitch, Maya Lotan-Pompan, Matan Elkan, Yeela Talmor-Barkan, Yaron Aviv, Maya Dadiani, Yonatan Tsodyks, Einav Nili Gal-Yam, Haim Leibovitzh, Lael Werner, Roie Tzadok, Nitsan Maharshak, Shin Koga, Yulia Glick-Gorman, Chani Stossel, Maria Raitses-Gurevich, Talia Golan, Raja Dhir, Yotam Reisner, Adina Weinberger, Hagai Rossman, and Le Song And special thanks to all participants of the Human Phenotype Project

Check out our MS describing the in vivo cycle of chaperonin TRiC/CCT, in a wonderful collaboration with Martin Beck's lab: nature.com/articles/s41586-0… 1) The study established TRiC's important function in folding newly translated proteins and defines its ATP-driven cycle

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. @abu_remaileh @Stanford_ChEMH, @ASAP_research, @BrainResilience, @CZI @cziscience Cell-Type Resolved Protein Atlas of Brain Lysosomes Identifies SLC45A1-Associated Disease as a Lysosomal Disorder biorxiv.org/content/10.1101/…
