Janus kinase 1

Target entity: Janus kinase 1
Context triple: [Xeljanz, targets, Janus kinase 1]

• A. Bruton tyrosine kinase
  Bruton tyrosine kinase is a key signaling enzyme in B cells that plays a crucial role in their development and function and is a major therapeutic target in certain blood cancers and autoimmune diseases.
• B. JAK-STAT signaling pathway
  The JAK-STAT signaling pathway is a key intracellular cascade that transmits signals from cell-surface receptors to the nucleus to regulate gene expression involved in cell growth, differentiation, immune function, and survival.
• C. IL-64
  IL-64 is a major east–west state highway in Illinois that runs from the Mississippi River through the Chicago metropolitan area.
• D. PLCγ2
  PLCγ2 is a phospholipase C isoform that functions as a key signaling enzyme in immune cells, mediating receptor-induced calcium mobilization and downstream activation pathways.
• E. IL-17A
  IL-17A is a pro-inflammatory cytokine produced mainly by Th17 cells that plays a key role in the pathogenesis of several autoimmune and inflammatory diseases.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
