Similar to treatment of mice with AZD5069/anti-PD1, we noted transfused immature neutrophils caused increased activation (CD86+) of intratumoural XCR1+ cDC1 cells and elevated CD8+ T cells in tumours, unlike mice transfused with equal numbers of mature neutrophils (figure 6J–L). The gene discussed is XCR1; the disease is neoplasm.
