Consistently, closer inspection of immune-related signatures from the TISIDB database revealed that a variety of subtypes of tumor-infiltrating lymphocytes (TILs) were significantly affected by GPX7 expression in LGG including γδ T cells, conventional CD4+ T cells (memory CD4+ T cells—Tcm CD4), CD8+ T cells (Activated and Central memory CD8+ T cells), B cells (memory and immature B cells), NK cells, NKT cells, myeloid-derived suppressor cell (MDSC), activated dendritic cell, and mast cell. This evidence concerns the gene CD4 and neoplasm.
