From: Desmin and dystrophin abnormalities in upper airway muscles of snorers and patients with sleep apnea
Muscle cross-section from the uvula of a patient stained for desmin and slow contractile protein MyHCI. Panel a shows merged staining for desmin and slow MyHCI, while panel b shows only desmin. Fibres expressing slow MyHCI (red, I) and fast MyHC II (green, II) are marked. Note that the deficiency of desmin is more common among fibres expressing MyHCI. Scale bar 50 μm
