TAPBP and glioblastoma: Positive correlations between VDR expression and immunoinhibitors of colony stimulating factor 1 receptor (CSF1R), galectin-9 (LGALS9) in TGCT, or GSF1R in GBM were shown in Figure 5B. Besides, VDR expression was positively associated with major histocompatibility complexes (MHCs) of β2-microglobulin (B2M), human leukocyte antigen-A (HLA-A) and tapasin-binding protein (TAPBP) in TGCT (Figure 5C).
