Fig. 1From: CTLA-4 correlates with immune and clinical characteristics of gliomaRelationship between CTLA-4 expression and clinical parameters of glioma. CTLA-4 expression in gliomas according to WHO grade status in the TCGA (a) and CGGA (b) databases. c Glioma tissues of different grades were immunostained for CTLA-4 using anti- CTLA-4 antibody and 3,30-diaminobenzidine (DAB; brown). Haematoxylin was used for nuclear counterstaining (blue). Numbers in parentheses indicate number and percentage of CTLA-4-positive samples out of number of total samples. Scale bars, 100 mm. CTLA-4 expression in gliomas according to IDH status in TCGA (d) and CGGA databases (e). * means p value < 0.05, ** means p value < 0.01, *** means p value < 0.001Back to article page
