Discovery of the day
Researchers have demonstrated that loss of SMPD4, a gene linked to severe human neurodevelopmental disorders including microcephaly and simplified gyral patterns, recapitulates these cortical malformations in a gyrencephalic ferret model — a significant advance given that Smpd4 knockout in mice shows only minor cerebellar defects. Using in utero electroporation combined with CRISPR-Cas9, the team showed that SMPD4 deficiency profoundly reduces basal intermediate progenitor proliferation, disrupts mitotic spindle orientation, impairs primary cilia formation, and causes severe neuronal migration defects, as confirmed by single-cell RNA sequencing of over 20,000 cells. For a neuroscientist developing preclinical models of neurological disorders, this work provides a critical gyrencephalic platform that bridges the translational gap between rodent studies and human cortical pathology, offering a mechanistically grounded system for investigating cortical malformations and testing potential therapeutic interventions.
