Trogocytosis of cancer cells by neutrophils was an active cellular process and only detected at 37 °C and not at 4 °C, as illustrated for FaDu cells (Figure 2D), was abrogated by α-lactose co-incubation (Figure 2E) and blocked upon inhibition of key trogocytosis kinase Syk (Figure 2F). Here, SYK is linked to cancer.
