High-resolution imaging of spiral protein and viral filaments

Cryo-EM of Helical Protein and Nucleoprotein Polymers at Near Atomic Resolution

NIH-funded research University of Virginia · NIH-11321560

Researchers are improving ultra-high-resolution cryo-EM imaging of spiral protein fibers and virus filaments to help scientists understand infections and diseases linked to these structures and ultimately benefit patients with infectious or protein-aggregation conditions.

What this research studies

From my perspective as a patient, the team uses cryo-electron microscopy to freeze and photograph tiny helical protein assemblies so their 3D shapes can be seen at near-atomic detail. They will image bacterial pili and flagella, bacterial secretion systems, archaeal viruses, actin filaments, and amyloid-like peptide tubes. By working across many different filaments and improving detectors, software, and computing, they aim to create general methods that help researchers study these structures more easily. Those clearer structures can guide future drug, vaccine, or diagnostic development targeting filament-related diseases.

Who could benefit from this research

Good fit: People with infections caused by filament-forming bacteria, survivors or contacts of filamentous viral infections, or patients with amyloid-related disorders might be relevant candidates to contribute samples or participate in follow-on translational studies.

Not a fit: Patients seeking immediate treatment benefits are unlikely to gain direct clinical benefit because this is a laboratory imaging project focused on basic structural knowledge.

Why it matters

Potential benefit: If successful, this work could reveal precise targets on bacterial and viral filaments or amyloid fibers that speed development of better antibiotics, antivirals, or therapies for protein-aggregation diseases.

How similar studies have performed: Cryo-EM has already produced many near-atomic structures and informed drug and vaccine research, so the approach is proven though applying it broadly to diverse helical polymers is still advancing.
