Nine TNBC-ST and nine TNBC-LT tumours were analyzed for M2-type TAMs by double-positive CD11b (monocyte-derived cells; Cassetta et al., 2016) and CD206 (M2-specific; Jaynes et al., 2020) labelling: TNBC-LT had relatively low TAM infiltration (mean 1.78%, range: 0.18–5.41%) than TNBC-ST (mean 7.34%, range: 3.76–16.80%; Figure 8B; Figure 8—figure supplement 1B). This evidence concerns the gene ITGAM and neoplasm.
