Discovery of the day
This study demonstrates that loss of SMPD4 in the developing gyrencephalic ferret cortex recapitulates key human neurodevelopmental phenotypes, including microcephaly and disrupted cortical lamination. The researchers show that SMPD4 deficiency leads to prolonged mitotic duration in neural progenitors, a profound reduction in basal intermediate progenitor cells, and severe neuronal migration defects, with many neurons failing to reach their appropriate cortical layers. For your research on neurodevelopmental disorders, these findings establish a critical mechanistic link between SMPD4 loss and human cortical malformations, providing a new gyrencephalic animal model to investigate the pathogenesis of SMPD4-related conditions and to test potential therapeutic interventions.
