CD36 and obstructive sleep apnea syndrome: Indeed, we have reported that hepatic CD36 expression increased with aging in mice and humans (13), but the age-dependent increases in hepatic CD36 expression were observed comparing young (20–38 years old) with aged individuals (50–83 years), thus we believe that age differences seen in our study population are not sufficient to explain the hepatic CD36 upregulation observed in OSA patients.
