What this research studies

This project maps age-related changes across tissues in fruit flies using cell-by-cell gene activity, tissue-specific protein measurements, and metabolite profiling combined with computational analysis. The team will build on the Aging Fly Cell Atlas and integrate single-cell transcriptomics, proteomics, and metabolomics to find communication signals between organs. They will test lifespan-extending interventions (like rapamycin and FOXO activation) and models that mimic muscle decline and human Tau-related brain damage to see how inter-organ signaling shifts. The aim is to reveal pathways that might be targeted to keep organs coordinated and healthier during aging.

Who could benefit from this research

Good fit: There is no direct patient enrollment because the work is done in fruit flies, but people with age-related metabolic or neurodegenerative conditions could benefit from therapies informed by these findings in the future.

Not a fit: Patients looking for immediate treatments or opportunities to participate will not benefit directly because this is preclinical lab research in an animal model.

Why it matters

Potential benefit: If successful, this work could point to biological targets to slow age-related decline or reduce risks for conditions linked to aging, such as metabolic disease or neurodegeneration.

How similar studies have performed: Previous animal studies using single-cell atlases and manipulating mTOR/FOXO pathways have shown links between inter-organ signals and lifespan, but translating those findings into human therapies remains preliminary.
