Abstract
BACKGROUND Pesticide residues have contaminated our environment and nutrition over the last century. Although these compounds are present at very low concentrations, their long-term effects on human health is of concern. The link between pesticide residues and Alzheimer's disease is not clear and difficult to establish. To date, no in vivo experiments have yet modeled the impact of this chronic contamination on neurodegenerative disorders. OBJECTIVES We investigated the impact of fungicide residues on the pathological markers of Alzheimer's disease in a transgenic mouse model. METHODS Transgenic (J20, hAPP Sw / Ind ) mice were chronically exposed to a cocktail of residues of cyprodinil, mepanipyrim, and pyrimethanil at 0.1 μ g / L in their drinking water for 9 months. We assessed the effects of fungicide residues on the pathological markers of the disease including A β aggregates, neuroinflammation, and neuronal loss. Then, we studied the dynamics of A β aggregation in vivo via a longitudinal study using two-photon microscopy. Finally, we investigated the molecular mechanisms involved in the production and clearance of A β peptides. RESULTS We found that a chronic exposure to three fungicide residues exacerbated aggregation, microgliosis, and neuronal loss. These fungicides also increased vascular amyloid aggregates reminiscent of cerebral amyloid angiopathy between 6 and 9 months of treatment. The mechanism of action revealed that fungicides promoted A β peptide fibril formation in vitro and involved an in vivo overexpression of the levels of the β -secretase -cleaving enzyme (BACE1) combined with impairment of A β clearance through neprylisin (NEP). CONCLUSIONS Chronic exposure of the J20 mouse model of Alzheimer's disease to a cocktail of fungicides, at the regulatory concentration allowed in tap water (0.1 μ g / L ), strengthened the preexisting pathological markers: neuroinflammation, A β aggregation, and APP β -processing . We hypothesize prevention strategies toward pesticide long-term exposure may be an alternative to counterbalance the lack of treatment and to slow down the worldwide Alzheimer's epidemic. https://doi.org/10.1289/EHP5550.

Abstract
A direct competitive enzyme-linked immunosorbent assay (dc-ELISA) was developed for determination of anilinopyrimidine fungicide mepanipyrim in vegetables. Two derivatives of mepanipyrim and mepanipyrim propanol type metabolite which carried carboxy acid were synthesized and conjugated with keyhole limpet hemocyanin. BALB/c mice were immunized to prepare anti-mepanipyrim monoclonal antibodies (MoAbs) by obtained conjugates. The dc-ELISAs based on the prepared MoAbs, MPP107 and MPP204, showed working ranges between 0.12 and 1.8 ng/mL with mepanipyrim for MPP107, 0.12 and 2.4 ng/mL with mepanipyrim for MPP204, and 0.2 ng/mL and 5.7 ng/mL with the mepanipyrim propanol type for MPP204. The dc-ELISAs showed the sufficient sensitivity to determine the mepanipyrim residues for the MRLs of 1-15 mg/kg among the majority of vegetables and fruits in Japan. Recovery and/or correlation results from HPLC suggested that the dc-ELISAs would be applicable to the residue analysis of mepanipyrim and its propanol type in vegetables.

Abstract
Cyprodinil is a pyrimidinamine fungicide, used worldwide by agriculture. It is used to protect fruit plants and vegetables from a wide range of pathogens. Benzo[a]pyrene (BaP) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) are toxic environmental pollutants and are prototypes of aryl hydrocarbon receptor (AHR) ligands. Although the structure of cyprodinil distinctly differs from those of BaP and TCDD, our results show that cyprodinil induced nuclear translocation of the AHR, and induced the transcriptional activity of aryl hydrocarbon response element (AHRE). Cyprodinil induced the expression of cytochrome P450 (CYP) 1A1, a well-known AHR-targeted gene, in ovarian granulosa cells, HO23, and hepatoma cells, Hepa-1c1c7. Its induction did not appear in AHR signal-deficient cells, and was blocked by the AHR antagonist, CH-223191. Cyprodinil decreased AHR expression in HO23 cells, resulting in CYP1A1 expression decreasing after it peaked at 9h of treatment in HO23 cells. Dexamethasone is a synthetic agonist of glucocorticoids. Cyprodinil enhanced dexamethasone-induced gene expression, and conversely, its induction of CYP1A1 expression was decreased by dexamethasone in HO23 cells, indicating its induction of crosstalk between the AHR and glucocorticoid receptor and its role as a potential endocrine disrupter. In addition to BaP, TCDD, and an AHR agonist, β-NF, cyprodinil also phosphorylated extracellular signal-regulated kinase (ERK) in HO23 and Hepa-1c1c7 cells, indicating its deregulation of ERK activity. In summary, our results demonstrate that cyprodinil, similar to BaP, acts as an AHR activator, a potential endocrine disrupter, and an ERK disrupter.
