Contribution of critical cytokine signaling to large granular lymphocytic leukemia (LGLL) immunopathogenesis. Interleukin (IL)-15, platelet-derived growth factor (PDGF), IL-2, and IL-6 are all central players in the immunopathogenesis of LGLL. Dysregulation of these cytokines leads to constitutive activation of their downstream signaling pathways such as PI3K, JAK/STAT, Ras/MAPK, and NF-kB. This leads to increased transcription of oncogenic driver genes such as c-MYC, cyclin D1, and BCL-xL, ultimately leading to increased malignant cell proliferation and survival.
