Tools to detect misfolded huntingtin protein

Genetically Encoded Probes of Huntingtin Misfolding

NIH-funded research University of Southern California · NIH-11145155

This project builds genetically encoded peptides that stick to early misfolded huntingtin so these toxic forms can be found and targeted in Huntington's disease.

What this research studies

The researchers will create small, genetically encoded peptide ligands designed to bind early misfolded forms of the huntingtin exon1 protein. They will test these probes in cells and animal models and with tissue samples to see if the probes reliably detect or bind the early species that seed aggregation. If binding works, the team will explore using the probes as biomarkers to detect disease-relevant misfolding and as tools to block seeding and spread. The work combines peptide-discovery, protein-structure expertise, and model-based testing led at the University of Southern California.

Who could benefit from this research

Good fit: People who carry the Huntington's disease gene expansion or have Huntington's disease would be the eventual candidates for related biomarker tests or future therapies.

Not a fit: People without the HTT gene expansion or those with non‑Huntington neurodegenerative conditions are unlikely to benefit from this specific work.

Why it matters

Potential benefit: If successful, these probes could enable earlier detection of toxic huntingtin species and point toward ways to block their spread, potentially slowing disease progression.

How similar studies have performed: Prior work targeting misfolded protein species has shown promise in lab models, but using genetically encoded peptides to bind early huntingtin intermediates is relatively novel.
