This article focuses on the central hub role of signal transducer and activator of transcription 6 (STAT6) in type 2 inflammation, systematically elaborating the molecular mechanisms by which the IL-4 and IL-13 signaling pathways converge at the STAT6 node to initiate downstream gene programs such as Th2 differentiation, IgE class switching, and eosinophil recruitment. It analyzes the four structural obstacles that STAT6, as a transcription factor, faces in the development of traditional small-molecule inhibitors, and explores how targeted protein degradation strategies circumvent the shallow-pocket challenge through the logic of "anchor only, no inhibition required."
