Figure Lengend Snippet: Immunohistochemical and flow cytometric analysis of gastric cancer tissue. (A) H&E histochemical staining of tumor-free area (left), tumor margin (middle), and gastric tumor site (right). (B) Representative IHC images for CD3 + , CD4 + , CD8 + , FOXP3, OX40, and OX40L in tumor-free area (left column), tumor margin (middle column), and gastric tumor site (right column) sections. (C) Immunofluorescence staining for the co-expression of CD3 + and OX40 in gastric cancer with anti-CD3 and anti-OX40 antibodies and DAPI for nuclear staining. (D) Flow cytometry analysis of OX40 expression in CD3 cells obtained from PBMC of gastric cancer patients (upper panel) and OX40 expression on CD3 on TILs in gastric cancer patients (low panel). Statistical analysis of all data were performed using one-way ANOVA. Data are shown as mean ± standard deviation. ns, nonsignificant; *, P<0.05; ***, P<0.001. ANOVA, analysis of variance; DAPI, 4',6-diamidino-2-phenylindole; H&E, hematoxylin & eosin; IHC, immunohistochemistry; OX40L, OX40 ligand; PBMC, peripheral blood mononuclear cells; TILs, tumor-infiltrating lymphocytes.
Article Snippet: Immunohistochemistry (IHC) analyses were performed using specific primary rabbit anti-human CD3 monoclonal antibody (Proteintech Group, Wuhan, China), mouse anti-human OX40 and rabbit anti-human OX40L monoclonal antibodies (CST, Danvers, MA, USA), and rabbit anti-human CD4 (Proteintech Group, Wuhan, China), mouse anti-human CD8 (Proteintech Group, Wuhan, China) antibody, rabbit anti-human FOXP3 monoclonal antibodies (CST, Danvers, MA, USA).
