“…The absence of overt MN loss may reflect the immaturity of MNs at the timepoints examined. In future studies, overcoming the challenges associated with long-term culture of MNs in monolayers (i.e., cell clumping and detachment) or use of three-dimensional culture models (i.e., spheroids, organoids) (Castellanos-Montiel et al, 2023;de Majo et al, 2023;Pereira et al, 2021) may enable neurodegeneration to be observed after several months of culture, without the need for exogenous treatments with stressors to elicit a phenotype.…”

Alternatively, transcription factor-mediated transdifferentiation towards specific neurons, avoiding intermediate proliferative pluripotent stem cell stage, may help retaining specific age-related and epigenetic features involved in neurodegenerative disorders (Mollinari et al, 2018).…”

“…These processes could also play a significant role in inhibiting proinflammatory pathways, including TNF-alpha production and the NF-κB inflammatory process [62,63]. Furthermore, granulin mutations may result in abnormal astrocyte and microglia-related mechanisms, such as their development and activation [64,65]. PSEN1 could also impact inflammatory pathways.…”
