A vaccine targeting aged cells mitigates metabolic disorders in obese mice

June 30, 2020

Aged, or senescent, cells are known to harm their surrounding younger cells by creating an inflammatory environment. A specific type of immune cell, called T cell, can accumulate in fat tissues in obese individuals in senescence, causing chronic inflammation, metabolic disorders and heart disease. To reduce the negative effects of senescent cells on the body, senotherapy was developed to target and eliminate these rogue cells. However, as this approach does not discriminate between different types of senescent cells, it has remained unknown whether specific depletion of senescent T cells can improve their adverse effects on organ physiology.
