Effects of lifelong spontaneous exercise on the M1/M2 macrophage polarization ratio and gene expression in adipose tissue of super-aged mice

In the adipose tissue (AT), an increase in the M1 macrophage (M1Ø)/M2 macrophage (M2Ø) polarization ratio can be a risk factor enhancing the inflammatory response during aging, as well as increasing the risk of chronic disease, thereby reducing lifespan, or at least reducing “healthy” lifespan. The purpose of this study was to analyze and compare the AT M1Ø/M2Ø polarization ratio at the final lifespan stage in aged and control animals performing...
