Summary: | Recently, Murphy et al. [1] demonstrated, through a challenging animal, cellular and human translational approach, that intermittent hypoxia induces a pro-inflammatory activation of adipose tissue macrophages (ATMs), promoting insulin resistance. They confirmed that intermittent hypoxia lowers insulin-mediated glucose uptake in 3T3-L1 adipocytes, and evidenced the interrelationship between inflammation and insulin resistance in the adipose tissue of mice exposed to intermittent hypoxia. They then measured the concentration of serum soluble CD163 (sCD163), an assumed pro-inflammatory biomarker reflecting macrophage activation, in obstructive sleep apnoea (OSA) patients classified according to their BMI and apnoea/hypopnoea index (AHI). This is the first time serum sCD163 has been evaluated in OSA patients, and its association with AHI is promising. With the aim of enhancing its relevance in further studies, we wish to discuss the following points. |
