The Interplay Between Neutrophils and CD8+ T Cells Improves Survival in Human Colorectal Cancer

Purpose: Tumor infiltration by different T lymphocyte subsets is known to be associated with favorable prognosis in colorectal cancer. Still debated is the role of innate immune system. We investigated clinical relevance, phenotypes, and functional features of colorectal cancer-infiltrating CD66b+ neutrophils and their crosstalk with CD8+ T cells.Experimental Design: CD66b+ and CD8+ cell infiltration was analyzed by IHC on a tissue microarray...
