Oxytocin Pathways of Intergenerational Transmission of Maternal Early Life Stress (ELS) – A Conceptual Framework ELS, such as childhood abuse and neglect, is a major risk factor in the etiology of psychiatric disorders (e.g., depression) and impaired parenting. These maladaptive long-term effects may also impact the next generation via multiple, partly overlapping pre- and postnatal pathways, such as maternal depression during pregnancy and postpartum and impaired parent-offspring interactions. Central oxytocin (OT) pathways, which can be altered by ELS, are known to be involved in the modulation of parenting behaviors, attachment formation, pre- and postnatal depressive symptoms, as well as MPF stress physiology. Thus, OT pathways may play an important role in the intergenerational transmission of ELS in humans. Gene-environment interactions and epigenetic modifications in OT pathways genes may moderate or mediate the assumed pre- and postnatal transmission pathways.
