In contrast, we observed that CCL7 deficiency had no effect on the infiltration of CD11b+CD11c−F4/80+ macrophages or CD11b+CD11c−Ly6G+ neutrophils into the tumor-burdened lungs, although the CD11b+CD11c− macrophages or neutrophils in the TME expressed certain levels of CCR1/2/336. The gene discussed is ITGAM; the disease is neoplasm.
