Modeling Neurodegeneration With Mutant-Tau Organoids

Greater understanding of the events preceding neurodegeneration is needed to design effective preventive and therapeutic strategies. In this issue of Cell, Bowles et al. (2021) report cerebral organoids that reveal early events in frontotemporal dementia pathogenesis due to mutations in microtubule-associated protein tau (MAPT), shedding light on a novel mechanism involving abnormal splicing and glutamate signaling.
