CCL4 and neoplasm: Altogether, we identified significant correlations for the chemoattractant C-X-C motif chemokine ligand 10 (CXCL10) as well as the chemokine (C-C motif) ligand 4 (CCL4) with higher densities of T cells in general and of CTLs, almost regardless of the tumor compartment analyzed (entire tumor, tumor cell nests or tumor stroma).
