For example, exposure of TSC2−/− cells to niclosamide or rottlerin in DPBS strongly decreased cell survival but addition of glucose was sufficient to almost completely rescue TSC2−/− cell survival, whereas both glucose and serum were necessary to prevent killing of TSC2+/+ by these chemicals (Fig. 9).
Stem cell approaches might also be applied in a variety of other ways to modulate the immune system to prevent killing of beta cells.
This weak reaction towards the tumor cell fusion partner HCT116 did however not prevent killing of HCT116 by Fc1 and Fc2-stimulated T cells as subsequently tested in cytotoxicity experiments.
