We explored the association between HAR1A and PVT1 (other LncRNA data missing) expression and immune infiltration levels of 6 types of immune cells, namely, B cells, CD8 + T cells, CD4 + T cells, macrophages, neutrophils, and dendritic cells in GBM and LGG using the TIMER dataset. This evidence concerns the gene CD8A and glioblastoma.
