From: Adipocytes promote tumor progression and induce PD-L1 expression via TNF-α/IL-6 signaling
PD-L1 expression of tumor tissue was increased in obese mice. a PD-L1 protein levels in tumor tissue of mice in MSG-IO model detected by western blot. b PD-L1 protein levels in tumor tissue of mice in DIO model detected by western blot. c Representative immunohistochemistry staining and quantitative analysis of CD8+ T cells in H22 tumor tissue. d Representative immunohistochemistry staining and quantitative analysis of CD8+ T cells in B16-F1 tumor tissue. Scale bar 50 μM. Data are expressed as mean ± SEM, n = 6 (western blot) and n = 3 (immunohistochemistry), *P < 0.05 and **P < 0.01 Vs control
