Janus Kinase (JAK) Inhibitor Overview:

Janus kinase (JAK) inhibitors, or jakinibs, are small, orally administered molecules, typically around 400 daltons in size. JAKs are enzymes called phosphotransferases that are associated with the intracellular portions of cytokine receptors and play a key role in transmitting signals that trigger immune responses. Various cytokines-including interleukins, interferons, colony-stimulating factors, and hormone-like cytokines such as erythropoietin-use JAKs to relay their signals. These cytokine receptors utilize different combinations of the four JAK family members: JAK1, JAK2, JAK3, and TYK2. First-generation JAK inhibitors, such as tofacitinib and baricitinib (and oclacitinib for veterinary use), typically block multiple JAKs, suppressing a broad range of cytokine activity, and are being explored for treating various autoimmune diseases.

The JAK-STAT signaling pathway is commonly employed by type I and II cytokine receptors, as well as receptors for interferons and growth factors. Because these receptors lack intrinsic enzymatic activity, they rely on JAKs to initiate downstream signaling, ultimately affecting gene expression. The name "Janus" refers to the Roman god of doorways, symbolizing JAKs' role in transmitting signals from the cell surface inward. Typically, each cytokine receptor is associated with a specific pair of JAKs, often forming heterodimers.

When a cytokine binds its receptor, the attached JAKs undergo transphosphorylation, activating themselves. The activated JAKs then phosphorylate the receptor, creating docking sites for STAT proteins. STATs, normally located in the cytoplasm, bind to these sites, become phosphorylated, dimerize (as homo- or heterodimers), and move into the nucleus to function as transcription factors, regulating gene expression. In mammals, seven STAT proteins exist, each linked to specific signaling pathways, mirroring the diversity of JAK functions.
