Target cancer-associated fibroblasts to potentiate PARP inhibitors
Besides eradicating tumour cells with deficiencies for homologous recombination, PARP inhibitors can induce the activation of CAFs within the TME via NF-κB/CCL5 pathway. CCL5 blockade blunts the reprogramming of CAFs conditioned by PARP inhibitors and potentiates PARP inhibitors.
