Differential expression of microRNA and predicted targets in pulmonary sarcoidosis

► This is the first study to profile microRNA expression in sarcoidosis tissues. ► MicroRNA in diseased sarcoidosis tissue shares a common microRNA profile. ► Peripheral blood cells of sarcoidosis patients exhibit a unique microRNA expression profile. ► MicroRNA expressed in sarcoidosis tissue and blood are predicted to target the WNT/TGFβ pathway.
