What this research studies
This work brings together two labs to study how damaged mitochondria send stress signals that overwhelm the cell's waste system (lysosomes) and lead to cell decline. Scientists will use cell models, yeast, and other laboratory systems to track a process called mitochondrial precursor overaccumulation stress (mPOS) and its effects on lysosomal function. The team will map the molecular steps of this mitochondria-to-lysosome signaling pathway to identify points that could be targeted by future therapies. Findings aim to explain why neurons fail in Alzheimer’s and related disorders and to point toward ways to protect brain cells.
Who could benefit from this research
Good fit: People with Alzheimer's disease or other age-related neurodegenerative conditions, or those willing to provide biological samples, would be most relevant for future participation or follow-up studies.
Not a fit: Individuals without neurodegenerative disease or those seeking immediate clinical treatment are unlikely to receive direct, short-term benefit from this basic laboratory research.
Why it matters
Potential benefit: If successful, this work could reveal new targets for drugs that slow or prevent cell damage in Alzheimer’s and other age-related neurodegenerative diseases.
How similar studies have performed: Prior laboratory studies have linked mitochondrial and lysosomal dysfunction and described mPOS, but this specific mitochondria-to-lysosome signaling pathway and its role in human neurodegeneration are largely novel.
