MSR1 and CD80 correlated with macrophages in basal-like tumors and between OLR1, ABCA1, ITGAV, CLEC5A and CD80 and macrophages in HER2 positive tumors.CD80 associated with CD274/PDL1 and FOXP3 in basal-like tumors suggesting that this biomarker can be expressed in different immune populations that co-exist within the same tumor microenvironment. This evidence concerns the gene FOXP3 and neoplasm.
