Moreover, TnTs can transfer cellular cargo between neighbouring cells.57, 58 However, our understanding of TnTs is in its infancy, and tremendous aspects of TnTs remain to be explored, although TnTs have been investigated in a wide variety of non‐cancer cells and malignant cells.59 Among them, TnTs have been reported in immune cells such as B cells, T cells, NK cells, dendritic cells and macrophages and in cancer cells of different origin.60 Here, TNNT1 is linked to cancer.
