Interestingly, gene set enrichment analyses of the sequencing data set from a patient with skin sarcoidosis treated with tofacitinib identified mTORC1 signaling and glycolysis, but also OXPHOS and fatty acid metabolism, next to “IFN-γ response” and “TNF-α signaling via NFκB” as inflammatory hallmarks of the affected patient skin [27,45]. Here, IFNG is linked to skin sarcoidosis.
