Antirheumatic, Disease Modifying; Antirheumatic, Miscellaneous; Janus Kinase Inhibitor Upadacitinib inhibits Janus kinase (JAK) enzymes, which are intracellular enzymes involved in stimulating hematopoiesis and immune cell function through a signaling pathway. JAKs activate signal transducers and activators of transcription (STATs), which regulate gene expression and intracellular activity. The inhibition of JAKs prevents the activation of STATs
