CCL5 and neoplasm: Furthermore, the previous study (Dangaj et al., 2019) has reported that the T cell infiltration requires tumour cell-derived CCL5, and this process is amplified by IFN-γ-inducible, myeloid cell-secreted CXCL9. As IFN-γ is encoded by IFNG, we named this amplification process as tumour cell-derived CCL5-IFNG-CXCL9 process.
