Session IV — Nobel Laureate Panel Discussion I

Breakthroughs Don’t Travel in Straight Lines

Three Nobel laureates — Carolyn Bertozzi (Chemistry 2022), Randy Schekman (Physiology/Medicine 2013), and Thomas Südhof (Physiology/Medicine 2013) — on what’s working, what’s hyped, and what they’d tell their younger selves. Moderated by Joseph Wu (Stanford).


Current Research Directions

  • Bertozzi: The glycocalyx as a transport problem — a new blood-brain barrier shuttle from glycoscience
  • Schekman: (1) Extracellular vesicles as biomarkers — trillions of “little sentinels” for early cancer detection; (2) Parkinson’s — running ASAP (Aligning Science Across Parkinson’s) with Sergey Brin’s family office, 150+ lab network
  • Südhof: From how synapses release to how connections form — and what goes wrong in schizophrenia and Alzheimer’s. Frontier: drugs that promote synaptic connectivity

The Translation Cliff

  • Bertozzi: The single most common failure mode: the biology doesn’t translate. PK divergence, species differences. Fixable if you survive the runway — in this funding climate, you usually can’t.
  • Schekman: Animal models for neurodegeneration are a “persistent embarrassment.” Newer alpha-synuclein knock-in mice are finally recapitulating Parkinson’s progression.
  • Bertozzi (solutions): Better organoids, humanized transgenics, lower regulatory barriers for Phase 0 human studies.

The Amyloid Cautionary Tale

  • Amyloid plaques are removable by antibodies — but removal does not reliably reduce dementia
  • Most Alzheimer’s patients carry APOE4/APOE3 defects, not APP mutations — decades and billions spent on the wrong frontier
  • ASAP’s design principle: lots of shots on goal; don’t repeat the amyloid mistake with Lewy bodies in PD
  • Brightest near-term target: LRRK2 — 30+ biotechs, including Denali’s brain-penetrant kinase inhibitor
  • Südhof excited about Montara (Kevan Shokat’s brain-only delivery platform, including brain-only LRRK2 inhibitor)

Exosomes: Diagnostics Yes, Delivery No

  • Schekman (diagnostics): Genuinely excited — a startup detecting stage-one ovarian cancer by reading three tumor antigens on individual particles
  • Schekman (delivery): Skeptical to dismissive — exosomes lack a fusogen; they get internalized, dumped to the lysosome, and degraded

How to Start a Company from Academia

  • Bertozzi: Start as SAB/consultant → find unmet need at your science intersection → spin out only with a technical co-founder from your own bench
  • Südhof: Co-found if you must — but only take the CEO seat if you’d genuinely enjoy it
  • Schekman: His yeast secretion work (1970s) led to 30% of the world’s recombinant insulin — he never ran the experiment himself

Funding the Gap

  • Philanthropy (ASAP) can do targeted miracles but can’t replace the NIH
  • Hybrid academic-industry models (GSK-Harvard, Stanford-Takeda) die on leadership turnover
  • Until incentive alignment improves, “keep submitting grants”

Advice to Young Scientists

  1. Follow the question, not the application
  2. Don’t romanticize the executive role
  3. Find a technical co-founder from your own bench
  4. Take the human-translation problem personally
  5. Resist the dominant hypothesis
  6. Aim at what no one knows how to do yet
