Fat-resident regulatory T cells (fTreg cells) accumulate in adipose tissue of mice as a function of age, but not obesity; mice without fTreg cells are protected against age-associated insulin resistance, but remain susceptible to obesity-associated insulin resistance and metabolic disease, indicating different aetiologies of age-associated versus obesity-associated insulin resistance.
