Moreover, tumor CD200R1 expression was strongly correlated (Spearman’s ρ > 0.5) with the expression of at least one of four commonly used T cell and myeloid infiltration markers (CD4, CD8A, CD11B and CD45) in tumors from multiple cancer types in The Cancer Genome Atlas (TCGA; [6]). This evidence concerns the gene ITGAM and neoplasm.
