Researchers from Kumamoto University studied the cellular aging process in naked mole-rats (NMRs), discovering an NMR-specific “natural senolytic” mechanism that removes senescent cells, potentially contributing to their resistance to aging. The research, utilizing both in vitro and in vivo methods, identified the role of serotonin metabolism and the enzyme MAO in this process, offering insights into anti-aging strategies and treatments against age-related diseases.
