Paediatrics: Antiepileptic drug exposure in pregnancy and neurodevelopmental disorder risk
Children born to mothers who took the antiepileptic drug sodium valproate during pregnancy may have a four to five-fold increased risk of developing neurodevelopmental disorders in early childhood, according to a study in Scientific Reports. Fifty of the 991 French children (5%) who were exposed to sodium valproate were diagnosed with neurodevelopmental disorders in their first five years, compared to 15,270 of 1,710,441 children (0.89%) not exposed to any antiepileptic drugs.

The team hope that their work will help highlight the impact that the Covid-19 pandemic could be having on the mental health of doctors and nurses worldwide. (2020-10-16)

Reelin-Nrp1 interaction regulates neocortical dendrite development
Reelin exhibits a context-dependent function during brain development; however, its underlying mechanism is not well understood. Here, we found that neuropilin-1 specifically binds to the C-terminal region of Reelin and acts as a co-receptor for canonical Reelin-receptor. The Reelin-Nrp1 interaction is essential for proper dendritic development in superficial-layer neurons. This study provides evidence of the context-specific function of Reelin regulated by the C-terminal residues. (2020-10-15)
