A Pivotal Role for Interleukin-27 in CD8+ T Cell Functions and Generation of Cytotoxic T Lymphocytes

Figure 2

IL-27 is a multifunctional cytokine that mainly activates both STAT1 and STAT3 together with STAT2, STAT4, and STAT5. IL-27 mediates its several biological functions by selectively utilizing these STAT1 and STAT3, which bind to distinct IL-27R subunits, IL-27Rα and gp130, respectively. IL-27 acts on various types of cells including CD4+ and CD8+ T cells, B cells, NK cells, macrophages, mast cells, and endothelial cells.
