Summary: | Bisphenol A (BPA) is a well-documented endocrine-disrupting chemical widely used in plastic products. In addition to its endocrine-disrupting effects, BPA exhibits immunotoxicity. Many countries have banned BPA because of its adverse effects on human health. In recent years, many chemicals such as bisphenol B (BPB), bisphenol E (BPE), bisphenol S (BPS), and bisphenol fluorene (BHPF) have been used to replace BPA. Because these replacement chemicals have chemical structures similar to that of BPA, they may also harm human health. However, their immunotoxicity and the molecular mechanisms underlying their toxicity remain largely unknown. The aim of this study was to investigate the immunotoxicity of BPA and its replacement chemicals, as well as the underlying mechanisms by exposing primary human lymphocytes to BPA and its replacement chemicals. Our results showed that exposure to BPA and its replacement chemicals altered the interleukin (IL) and cytokine production, such as IL-1b, IL-5, IL-6, IL-8, interferon alfa-2b (IFN-a2B), and tumor necrosis factor alpha (TNF-α), in the lymphocytes. Among these, BPA and BHPF caused a greater inhibition. Using comparative transcriptomic analysis, we further investigated the biological processes and signaling pathways altered by BHPF exposure. Our data highlighted alterations in the immune response, T cell function, and cytokine-cytokine receptor interactions in human lymphocytes through the deregulation of gene clusters. In addition, the results of ingenuity pathway analysis demonstrated the inhibition of T lymphocyte function, including differentiation, movement, and infiltration. Our results, for the first time, delineate the mechanisms underlying the immunotoxicity of BHPF in human lymphocytes.
