Abstract

The developmental origins of health and disease concept illustrates that exposure in early life to various factors may affect the offspring's long‑term susceptibility to disease. During development, the nervous system is sensitive and vulnerable to the environmental insults. Polychlorinated biphenyls (PCBs), which are divided into dioxin‑like (DL‑PCBs) and non‑dioxin‑like PCBs (NDL‑PCBs), are synthetic persistent environmental endocrine‑disrupting chemicals. The toxicological mechanisms of DL‑PCBs have been associated with the activation of the aryl hydrocarbon receptor and NDL‑PCBs have been associated with ryanodine receptor‑mediated calcium ion channels, which affect neuronal migration, promote dendritic growth and alter neuronal connectivity. In addition, PCB accumulation in the placenta destroys the fetal placental unit and affects endocrine function, particularly thyroid hormones and the dopaminergic system, leading to neuroendocrine disorders. However, epidemiological investigations have not achieved a consistent result in different study cohorts. The present review summarizes the epidemiological differences and possible mechanisms of the effects of intrauterine PCB exposure on neurological development.
