TL;DR
The findings identify maternal sleep deprivation as an early-life insult that programs a Trem2-centred microglial axis shaping hippocampal circuits and long-lasting cognitive and behavioral alterations, and suggest microglial Trem2 as a candidate target for mitigating neuropsychiatric risk associated with adverse sleep in pregnancy.
ABSTRACT The early‐stage hippocampal development depends on precise synaptic remodeling, processes where microglia play indispensable roles. Disruption of this event reshape hippocampal neural circuit architecture and heighten the risk for long‐term memory, learning, and behavioral deficits. Manganese (Mn), a widesprea...

Prenatal maternal immune activation (MIA) during pregnancy is a prominent environmental contributor to neurodevelopmental disorders and psychiatric conditions in offspring, but the precise brain-region- and cell-type-specific mechanisms remain unclear. Using a lipopolysaccharide (LPS)-induced MIA mouse model, we show...

Prenatal exposure to fine particulate matter (PM2.5) is a critical risk factor for neurodevelopmental impairment in male offspring; however, its effects on synaptic development and the underlying transcription factor (TF) regulatory networks remain poorly understood. To address this, we established a mouse model of pre...

It is shown that 24S,25-epoxycholesterol, an oxysterol enriched in the fetal brain and dysregulated in NDDs, enhances neurogenesis while altering the distribution of GABAergic neuronal subtypes, suggesting that aberrant oxysterol signaling contributes to the pathogenesis of NDDs.

BACKGROUND
Stress is a major determinant of psychopathology in which coping and cognitive impairment arise from abnormal glucocorticoid activity and brain derived neurotrophic factor (BDNF)-dependent neuroplasticity in the hippocampus. The endocannabinoid system modulates stress and hippocampal functioning since early...

Pediatric obstructive sleep apnea (POSA) is a common childhood disease that often causes aberrant brain development and cognitive deficits. The pathophysiological underpinnings of cognitive impairments in POSA remain unclear. Here, we examined cellular and molecular aspects of pathology in a mouse model of POSA that fe...
