While Liu et al. dissected the molecular signaling pathway behind IFN-γ-mediated tumor cell-dormancy, Farrar et al. (192) discovered in 1999 that IFN-γ produced by CD8+ T cells played a major role in inducing tumor cell dormancy in vivo; however, the authors did not dissect the mechanism of action. The gene discussed is IFNG; the disease is neoplasm.
