Moreover, TIMER analysis showed a strong association between LILRB1 expression and infiltration of B cells (r = 0.736, P = 1.53e-82), CD4+T cells (r = 0.9, P = 2.80e-173), macrophages (r = 0.78, P = 9.35e-98), neutrophils (r = 0.823, P = 2.28e-118), and dendritic cells (r = 0.919, P = 3.31e-193) in LGG and B cells (r = 0.243, P = 4.77e-07), CD4+T cells (r = 0.372, P = 3.49e-15), macrophages (r = 0.111, P = 2.35e-02), neutrophils (r = 0.415, P = 8.04e-19) and dendritic cells (r = 0.526, P = 3.60e-31) in GBM (Fig. 7A). Here, CD4 is linked to glioblastoma.
