ADIPOQ and obesity due to melanocortin 4 receptor deficiency: Levels of some inflammatory markers and cytokines such as C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and macrophage migration inhibitory factor (MIF) are elevated, whereas concentrations of adiponectin, a protein hormone that exerts anti-inflammatory activities, are reduced in obesity [28–34].
