Extended Data Fig. 7: Immunofluorescence staining of FcεRIα in human lung tissues.
From: Inhibition of immunoglobulin E attenuates pulmonary hypertension
a. Representative images showing staining of tryptase (green) and FcεRIα (red) in lung sections of control subjects (non-PAH) and PAH patients. Scale bar=50 μm. b. Representative images showing staining of α-SMA (green) and FcεRIα (red) in lung sections of control subjects and PAH patients. Scale bar=50 μm. c. Representative images showing staining of CC10 (green) and FcεRIα (red) in lung sections of control subjects and PAH patients. Scale bar=50 μm. The arrows indicate examples of positive-staining cells. PA, pulmonary artery; AE, airway epithelium. For a-c, the same results were observed in 4 individual samples each group.
