  "account": "Postpartum depression (PPD) affects approximately 20% of mothers, while an even larger percentage (up to 75%) experience postpartum blues. Despite its prevalence, the neurobiological basis of PPD remains incompletely understood. Research suggests that deficits in neurosteroid signaling contribute to vulnerability to postpartum behavioral issues. Mice with reduced expression of the {delta} subunit-containing GABAARs (Gabrd -/- or Gabrd +/-) display postpartum-specific behavioral deficits. Allopregnanolone and its analogs (SGE-516) have been shown to improve postpartum outcomes and modulate oscillations in the basolateral amygdala (BLA), which is involved in emotional processing.\n\nIn this study, the researchers investigated how postpartum behavioral differences in wild-type, Gabrd+/-, and SGE-516-treated Gabrd+/- dams were influenced by theta oscillations in the BLA. Theta oscillations in the BLA have been associated with altered behavioral responses to stress or threat. The findings revealed that Gabrd+/- dams exhibited a failure to respond appropriately to their own pup calls, with reduced theta oscillations correlating with maternal approach behavior deficits. These issues were ameliorated with SGE-516 treatment.\n\nMoreover, an unbiased Multi-Objective Sequencing (MoSeq) analysis identified altered behavioral syllable expression in Gabrd+/- dams in response to pup calls, which were restored upon SGE-516 treatment. These results provide network and behavioral signatures of postpartum behavioral deficits and elucidate the effects associated with neurosteroid-based treatments.",

Despite this high incidence, we still have an incomplete understanding of the underlying neurobiology of PPD. Deficits in neurosteroid signaling has been implicated in the vulnerability to postpartum behavioral deficits and mice with reduced expression of {delta}…",
