The Human Cell Is Wildly Complex. Can AI Decode It? | Silvana Konermann | TED

Summary

Silvana Konermann argues that complex diseases such as Alzheimer’s, heart disease, stroke, and many cancers are difficult to treat because they arise from different combinations of genetic and environmental risk factors in each person. Unlike an infection with a single cause, these diseases may have many possible biological targets, and researchers often test them one hypothesis at a time.

She describes a strategy for building a “virtual cell” that could help researchers predict how cells respond to interventions:

• Measure: Use single-cell RNA sequencing to capture RNA expression, a changing “language” that reflects what is happening inside a cell.
• Change: Use CRISPR to turn individual genes up or down in targeted experiments.
• Understand: Train AI on the resulting measurements and perturbations to predict how a cell’s state may change.

The team has completed about 60 million physical experiments and plans to conduct at least one billion over four years, using barcoding to run many experiments in pooled batches. The goal is for a model to identify interventions that could shift diseased cells toward healthy states, including across different patients. For example, it might help identify ways to alter disease-associated microglia, immune cells in the brain.

Konermann says the goal is a universal virtual cell that can generalize to cell types or disease states it was not specifically trained on. An early model and an interface called the State Designer are available as initial steps, but she emphasizes that the model is not yet accurate enough for broad practical use. The team plans to release a tool for public testing and runs an annual Virtual Cell Challenge; the first challenge drew 1,000 teams.

Konermann expects this approach could eventually make biological research more comprehensive and data-driven than testing one hypothesis at a time. She also addresses safety: the proposed tool is intended for human cells, not viruses. However, she says it could help researchers understand how a virus affects a human cell and support defenses against infection.
