Additionally, tumor cells and tumor-derived fibroblasts express chemokine ligand 2 (CCL2) (141), IFN-γ-inducible protein 10 (IP-10) (107), monocyte chemoattractant protein 1 (MCP-1), macrophage inflammatory protein 1α (MIP-1α), MIP-1β, and regulated on activation, normal T cell expressed and secreted (RANTES) to promote recruitment of activated Vδ1+ and Vδ2+ γδ T cells to the TME (140). The gene discussed is CCL4; the disease is neoplasm.
