TDP43 breakdown in ALS: how brain cells use lysosomes to clear trouble

Official title: TDP43 Degradation by the Lysosomal Proteases in Amyotrophic Lateral Sclerosis

Funded at University of California, San Francisco · NIH-11362153 · Data updated 2026-11-12

This grant supports a clinician-scientist at UCSF as they study how the protein TDP-43 is removed by lysosomal enzymes to protect nerve cells in ALS.

Who could benefit from this research

Could help

Patients with amyotrophic lateral sclerosis or those at risk due to family history may benefit indirectly from advances in understanding ALS mechanisms and potential future therapies.

Less likely to help

The grant itself does not involve patient participation or direct treatment, so immediate benefits to any individual patient are not expected during the funded period.

What this research studies

A clinician-scientist at UCSF will receive mentored training to uncover how lysosomes break down TDP-43 and how this process affects motor neuron survival in ALS. The work focuses on basic cellular mechanisms in neurons with the goal of guiding new therapies to prevent neuron death and preserve function. Through hands-on research and mentoring, the researcher will develop skills to translate cellular findings into potential ALS treatments that could slow or halt disease progression.

Why it matters

Potential benefit: If successful, the research could illuminate new targets to protect motor neurons and guide therapeutic strategies for ALS patients.

How similar studies have gone: Previous work has connected TDP-43 pathology and lysosomal pathways in ALS, but detailed mechanisms remain incompletely understood, making this an important next step.
