Intriguingly, an expansion of pro-angiogenic, decidual-like NK cell subset has been found in solid cancers: these dNK-like, termed tumor-infiltrating (those present in tumor tissues-TINKs) and tumor-associated (NKs in the peripheral blood-TANKs) NK cells acquire a CD56brightCD16lowCD9+CD49a+ phenotype, can release pro-angiogenic factors and support EC proliferation, migration and ability to form capillary-like structures (18, 45, 48–51). Here, ITGA1 is linked to neoplasm.
