MRC1 and neoplasm: Previous studies reported that pharmacologic FAK inhibition, on genetic PDAC mouse (KPC) (Jiang et al, 2016) or immunocompetent PDAC‐bearing mouse models (Stokes et al, 2011), decreased numbers of tumour‐infiltrating immunosuppressive cells such as tumour‐infiltrating myeloid‐derived suppressor cells (MDSCs), CD206+ tumour‐associated macrophages and CD4+FOXP3+regulatory T cells (Tregs).
