How GPT‑5 Helped an Immunologist Solve a Three‑Year Puzzle on Glucose's Effect on T Cells

Friends — from the OpenAI ecosystem: GPT‑5 helped immunologist Derya Unutmaz resolve a three‑year puzzle: how glucose affects T‑cell specialization.

- Essence: a 2022 experiment showed that cells in deoxyglucose media produced explosive Th17 expansion, while simply reduced glucose did not.
- AI contribution: the model proposed a mechanism — deoxyglucose impairs IL‑2 synthesis, removing a barrier to Th17 differentiation, and correctly predicted outcomes.
- Practice: GPT‑5 functions as a colleague — speeding reviews, modeling and experimental design, but demands expert validation and responsible application.

Why this matters: such tools can materially accelerate biomedical research.
