MAPT and frontotemporal dementia: Alike FTD‐neurons, glutamate‐induced [Ca2+]c rise in genetically engineered 10+16 iPSC‐derived neurons presented a higher peak amplitude, larger AUC, and slower [Ca2+]c recovery compared to their isogenic wt tau control, that were reverted with the AMPA/kainate antagonist CNQX (Figure 4B, Figures 5G–5I, Figures S5B, S5C in supporting information).
