Jennifer et al. reported that the healthy donor human CD14+ monocytes could acquire MDSC phenotypes (reduced CD14 but not CD11b expression) and immunosuppressive properties (increased immunosuppressive interleukin-10, transforming growth factor-β (TGF-β), and B7-H1 expression) when cultured with human glioblastoma cell lines (28). This evidence concerns the gene CD14 and glioblastoma.
