To reassure the transfer of cancer CD39 into interacting T cells, NSCLC cells were transfected with GFP-labeled CD39 expression vector and then co-cultured with T cells, and we observed a significant load of GFP-labeled CD39 protein in interacting T cells using flow cytometry and confocal microscopy (Fig. 5A, B), demonstrating an efficient transfer of CD39 protein from NSCLC into those T cells. Here, ENTPD1 is linked to cancer.
