A Bi-Adjuvant Senolytic Nanovaccine Modulating Dendritic Cell Senescence Ameliorates Aging-Related Metabolic Dysfunction
Vaccinated naturally aged female C57BL/6 mice reportedly showed ~12% longer median lifespan, and high-fat-diet mice vaccinated at 60 weeks had median lifespan of 91 weeks vs 79-83 weeks in comparators. Proof-of-concept only: 10 mice per group, short-lived controls.

Full Abstract
Gpnmb-directed nanovaccine (CpG adjuvant on a CK5 protein scaffold, ~90 nm particles) tested in aged and high-fat-diet mice.
Key Findings
- 01
Targets Gpnmb on senescent cells via vaccination; modulates dendritic-cell senescence
- 02
~12% longer median lifespan in naturally aged mice vaccinated at 75 weeks (n=10/group)
- 03
Improved aging-related metabolic dysfunction in aged / high-fat-diet mice
Structured Methods
- Study Design
- Preclinical Study
- Sample Size
- Not reported
- Study Duration
- Not reported
- Methodology
- Mouse lifespan and metabolic cohorts; in vitro D-galactose senescence model; AlphaFold3 structural predictions
- Limitations
- Small lifespan cohorts (10/group); control mice relatively short-lived for C57BL/6; one senescence-marker experiment lacked untreated controls; mechanism partly computational (AlphaFold3) or in vitro; publication date approximate (Lifespan.io coverage 30 Oct 2026); not replicated.
