GNLY and neoplasm: We showed that in vitro, Vδ2+γδ T cells released substantial amounts of granulysin in response to culture with Daudi tumour cells, known to be sensitive to Vδ2+γδ T‐cell killing, and that they could also release this molecule, albeit to a lesser degree, in response to Raji cells (resistant to Vδ2+γδ T‐cell killing) and Raji cells pre‐treated with ZA.
