GPT-Rosalind surfaced a new lead for drug discovery: could restoring cholesterol transport protect neurons from degeneration?
DCTN1 is a gene linked to Perry syndrome, a rare neurodegenerative disorder. In mouse-brain data, disrupting it increased expression of genes involved in making cholesterol. GPT-Rosalind suggested a possible explanation: cholesterol may not be reaching where neurons need it.
That gives scientists a specific mechanism to test and, if confirmed, a direction for developing new treatments for neurodegenerative disorders.
With @perturbai_tx and @scrippsresearch, a team of thousands of GPT-Rosalind agents worked in parallel, connecting gene-expression results from millions of mouse brain cells with scientific literature in just 32 minutes. We’re now expanding this collaboration to identify new drug targets.

In the same mouse-brain dataset, GPT-Rosalind found a possible clue to why TSC2 mutations tend to cause more severe tuberous sclerosis than TSC1 mutations.
The two genes work together to regulate mTOR. Yet in one group of cerebellar neurons, disrupting TSC2 changed the expression of dozens of genes, including genes involved in neuronal communication. Disrupting TSC1 had little effect on gene expression in the same cell type.
Existing treatments already target mTOR. Do they reverse these changes, or is there more to TSC2’s role in these neurons?

My @scrippsresearch colleague @xinjin and her team are doing amazing brain biology discovery work with 2,000 agents, PerturbAI, in collaboration with @OpenAI

The interesting part isn’t that AI “discovered a drug target in 32 minutes.”
It found a mechanistic thread worth testing:
DCTN1 disruption → ↑ cholesterol synthesis genes → possible cholesterol transport failure → could restoring distribution protect neurons?
That’s where AI-assisted science gets interesting: not replacing the experiment, but finding the experiment worth running next.
Who should a neurodegeneration researcher contact about getting involved as this expands? My partner works on exactly this at a leading research institute in Italy @perturbai_tx @scrippsresearch
This is where AI could truly transform medicine.
Discovering previously unrecognized cellular pathways, identifying new therapeutic targets, and uncovering mechanisms of disease at a speed that was unimaginable just a few years ago.
AI is not just accelerating drug discovery. It is expanding the boundaries of what we can potentially treat.
For millions of patients living with diseases we still cannot cure, this represents extraordinary hope.
Now do Multiple Sclerosis. 🧠🔬

Neurodegeneration often hides in plain sight: sometimes, restoring a basic function like cholesterol transport does more for neurons than the latest molecular tweak. It’s a reminder that repair can beat reinvention.
