Does chronic intermittent hypoxia alter density of aminergic terminals and receptors in the hypoglossal motor nucleus?
CIH-elicited increase of NE and 5-HT terminal density and increased expression of α₁-adrenoceptors in the XII nucleus may lead to augmentation of endogenous aminergic excitatory drives to XII motoneurons, thereby contributing to the increased upper airway motor tone in patients with OSA.
ASCA positivity in TA was similar to that found in UC and healthy controls. No ANCA antibodies were detected among patients with TA.
