Review: Endocrine disrupting chemicals and immune responses: a focus on bisphenol-A and its potential mechanisms

Abstract

Endocrine disrupting chemicals (EDCs) have become of concern for a variety f health issues. Due to their effects on the endocrine system they have been thoroughly examined with regards to sexual dysfunction, malformation, and cancers of reproductive origin. Bisphenol-A (BPA) is a widely studied EDC and has been characterized regarding its estrogenic effects on a variety of cell types. BPA also alters immune responses. In this review, we examine some of the documented effects of EDCs, with a focus on BPA that pertain to modulation of the immune system and various immune cell populations. We highlight the multiple actions of BPA on altering T cell subsets, B cell functions, and dendritic cell and macrophage biology. Finally, we consider that these immunological activities of BPA may be mediated through estrogen receptor signaling, arylhydrocarbon receptor, and the peroxisome proliferator-activated receptor family of nuclear receptors.
