Bisphenol A exposure during gestation and lactation in mice: sex-specific consequences on oligodendrocytes and myelination.

Bisphenol A (BPA), a ubiquitous environmental endocrine disruptor, is suspected of disturbing brain development through largely unknown cellular and molecular mechanisms. In the central nervous system, oligodendrocytes are responsible for forming myelin sheaths, which enhance the propagation of action potentials along axons. Disruption of axon myelination can have lifelong consequences, making oligodendrocyte differentiation and myelination critical stages of brain development.

Microglial Depletion, a New Tool in Neuroinflammatory Disorders: Comparison of Pharmacological Inhibitors of the CSF-1R.

A growing body of evidence highlights the importance of microglia, the resident immune cells of the CNS, and their pro-inflammatory activation in the onset of many neurological diseases. Microglial proliferation, differentiation, and survival are highly dependent on the CSF-1 signaling pathway, which can be pharmacologically modulated by inhibiting its receptor, CSF-1R. Pharmacological inhibition of CSF-1R leads to an almost complete microglial depletion whereas treatment arrest allows for subsequent repopulation.

Chronic Inflammation Offers Hints About Viable Therapeutic Targets for Preeclampsia and Potentially Related Offspring Sequelae.

The combination of hypertension with systemic inflammation during pregnancy is a hallmark of preeclampsia, but both processes also convey dynamic information about its antecedents and correlates (e.g., fetal growth restriction) and potentially related offspring sequelae.

C-section and systemic inflammation synergize to disrupt the neonatal gut microbiota and brain development in a model of prematurity.

Infants born very preterm (below 28 weeks of gestation) are at high risk of developing neurodevelopmental disorders, such as intellectual deficiency, autism spectrum disorders, and attention deficit. Preterm birth often occurs in the context of perinatal systemic inflammation due to chorioamnionitis and postnatal sepsis. In addition, C-section is often performed for very preterm neonates to avoid hypoxia during a vaginal delivery.
