IFN-gamma

Primary Th1 cytokine produced by CD4+ Th1, CD8+ CTLs, and NK cells; binds IFNGR1/2 → JAK1/2 → STAT1 → MHC-II, IDO1, and antimicrobial gene induction. Central mediator of adaptive cellular immunity and antitumor immunosurveillance; evaded by PD-L1 upregulation in tumors.

Also known as: interferon-gamma, IFNG, type II interferon, immune interferon, IFN-γ, T cell interferon
