In light of previous findings in OAC patients demonstrating that CCR1 and CX3CR1 signalling in T cells led to the erroneous migration of T cells away from the tumour and toward the omentum and liver, as well as findings detailing how their antagonism enhanced their migration to the OAC TME [19,24,31,32,37], we sought to investigate if CCR5 antagonism might affect the migration of T cells to the OAC TME. This evidence concerns the gene CCR5 and neoplasm.
