Fig. 3From: CD137 agonist induces gastric cancer cell apoptosis by enhancing the functions of CD8+ T cells via NF-κB signalingCD137 was primarily expressed on CD8+ T cells and a CD137 agonist enhanced CD8+ T cell proliferation. a CD137 expression was examined using IF. b The ratio of CD8 in CD3 before isolation. c The ratio of CD8 in CD3 of an individual patient before isolation is presented. d The ratio of CD8 in CD3 after isolation. e, Ratio of CD8 in CD3 of an individual patient after isolation is presented. f and g CD8+ T cell proliferation in response to a CD137 agonist.
