In agreement with our results, it was previously published that tau‐mediated NMDA receptor impairment underlies the dysfunction of a selectively vulnerable network in a mouse model of FTD,46 the enhanced effect of mutated tau on excitotoxicity via NMDA,47 and the involvement of calcium dysregulation in the mechanism of cell death of FTD iPSC‐neurons with different MAPT mutations.4 Here, MAPT is linked to frontotemporal dementia.
