Figure 1A reveals a notable negative correlation between the frequency of tumor-infiltrating CD45+CD11b+ cells and CD45+CD3+ T cells. Subsequently, the analysis focused on TAMs, particularly looking at the expression levels of CD86 and PD-L1, both markers indicative of their activation state and potential to stimulate lymphocytes. Figure 1B reveals a significantly greater frequency of TAMs positive for PD-L1 in comparison to the CD86 marker. This evidence concerns the gene CD274 and neoplasm.
