What we've learned

Eight experiments. Honest writeups. Reproducible.

Each one asks one question, runs Gemma 4 or its predecessors over real PubMed papers, and ships the result, including what didn't work.

EXP-007 Jun 27, 2026

The lipid-proteostasis cascade: what breaks first in HD?

The primary pathogenic event is hypothesized to be the disruption of cellular membrane microdomains by mutant huntingtin (mHTT), establishing a lipid $\rightarrow$ proteostasis failure cascade.

EXP-008 Jun 29, 2026

Does HD's damage start in the epigenome, before symptoms?

Epigenetic dysregulation (TET1 suppression) is an early molecular event preceding clinical HD symptoms, establishing a viable pre-symptomatic intervention window.

How the Hub works

Pick a topic. Read what it means. Then do something with it.

Huntingtin-lowering (ASOs and gene therapy)

A strategy worth watching A simple idea, big stakes

Picture the huntingtin protein as a faulty thermostat that someone left turned up too high. Huntingtin-lowering programs try to turn the dial back down, so the brain has less of the harmful version to deal with in the first place.

What it is

A family of treatments that tries to make the brain produce less of the huntingtin protein. Some are repeat injections, some are a one-time gene therapy.
