For example, one study reported mean IL-8 concentrations of 4.3 ± 1.4 pg/mL in a population with obesity [69], and another described mean IL-17A levels in healthy subjects (10.1 ± 3.0 pg/mL) and patients with severe obstructive sleep apnea–hypopnea syndrome (20.3 ± 3.9 pg/mL) as higher than those observed in the present study [70]. The gene discussed is CXCL8; the disease is obesity due to melanocortin 4 receptor deficiency.
