Official title: Mechanisms and rescue of axonal degeneration in hereditary spastic paraplegia neurons

Funded at University of Illinois at Chicago · NIH-11528579 · Data updated 2026-11-12

Aimed at understanding why certain nerve fibers die in hereditary spastic paraplegia and ALS by studying neurons made from patients’ own stem cells.

Who could benefit from this research

Could help

Patients with hereditary spastic paraplegia or ALS, or cells derived from them, may contribute iPSC models for study.

Less likely to help

Individuals without HSP/ALS or without access to patient-derived iPSCs may not directly benefit from this research.

What this research studies

Researchers will use neurons created from patients’ induced pluripotent stem cells to study how spatacsin and spastizin affect autophagy, lysosome transport, and mitochondrial health. The team will look at how these processes interact to cause axon degeneration and test ideas for rescuing nerve damage. The work builds on prior findings of impaired mitochondrial dynamics and altered autophagy in patient-derived neurons. Results could point to new targets to protect nerves in people with HSP or ALS.

Why it matters

Potential benefit: Findings could lead to new strategies to prevent or slow nerve degeneration in HSP and ALS.

How similar studies have gone: Previous studies with patient-derived neurons have shown relevant disease mechanisms; this project extends those findings to axonal transport and autophagy.
