A single intravenous reelin injection restores corticosterone-induced neurochemical and behavioral alterations in dams during the post-partum period.

Introduction: Treatment with the synaptic plasticity protein reelin has rapid antidepressant-like effects in adult corticosterone (CORT)-induced depressed rats, whether administered repeatedly or acutely. However, these effects remain unexplored in the context of post-partum depression (PPD).

Methods: This study investigated the antidepressant-like effect of a single injection of reelin in a CORT-induced model of PPD.
