In the last few years, increased systemic levels of several inflammatory markers, including TNF-α, IL-6, IL-8 and ICAM-1, have been associated with OSA, suggesting that inflammation plays an important role in the pathophysiology of OSA, and possibly its vascular complications [7], [8], [9], [10], [11]. Here, ICAM1 is linked to obstructive sleep apnea syndrome.
