TGFB1 and neoplasm: They demonstrated that when miR‐23a and TGF‐β were delivered by microvesicles isolated from hypoxic IGR‐Heu, K562 and T1 tumour cells into MK‐92 cells, then the expression of CD107a/LAMP1 was reduced and the number of NKG2D activator surface receptors was decreased in these cells.
