QHF + ADM recruited CD4+ and CD8+ T cells in the A20 tumor sites. A. Representative images of IHC staining for CD4+ T cell among the three groups (200×). B. Bar plot of the positive cell rate of CD4+ T cells of the control group (n = 3), ADM group (n = 3), and QHF + ADM group (n = 3). C. Representative images of IHC staining for CD8+ T cells among the three groups (200×). D. Bar plot of the positive cell rate of CD8+ T cells of the control group (n = 3), ADM group (n = 3), and QHF + ADM group (n = 3). E. Bar plot of TGF-β, IFN-γ, CXCL10, and IL-6 levels based on ELISA of the control group (n = 3), ADM group (n = 3), and QHF + ADM group (n = 3).F. 18F FDG PET-CT scan of the ADM group (n = 1), and QHF + ADM group (n = 1). G. Expression of TLR2, p38 MAPK, and β-actin by western blot. Data are presented as the mean ± standard errors, *p < 0.05; **p < 0.01
