Serotonergic and Cholinergic Imbalance in the Offspring of Rats Exposed to Bisphenol A and Bisphenol S During Pregnancy and Lactation: Short- and Long-Term Effects.

ABSTRACT: Considering the increased risk of cognitive deficits and mood disorders programming associated with bisphenol exposure, we used a preclinical model to identify short- and long-term effects of early exposure to Bisphenol A (BPA) and its replacement, Bisphenol S (BPS), on the central cholinergic and serotonergic systems. Wistar female and male rats born to dams exposed to BPA or BPS (both at 10 μg/kg/day or 50 μg/kg/day) during pregnancy and lactation were euthanized at weaning or adulthood. Cholinergic and serotonergic biomarkers were assessed in the frontal cortex and pons + medulla oblongata. BPA and BPS disrupted these systems, with outcomes depending on the specific bisphenol, biomarker, and time point. Effects also varied across brain regions and between sexes. The nicotinic cholinergi
