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 immunostained for desmin (Des, green color, a) and alpha-actinin (α-actinin, red color, b). Panels c shows merged staining for desmin, alpha-actinin, and nuclei (DAPI). A desmin negative fibre weakly stained for alpha-actinin (*) and a fibre with immunoreaction for both desmin and alpha-actinin (+). Note the large variability in staining pattern and intensity for both desmin and alpha-actinin. Scale bar 25 μm
