Additionally, we established a 3D human AD model by transducing ReN cells with <em>APP</em> and <em>PSEN1</em> mutations to assess the effects of formaldehyde in an AD genetic background. Long-term formaldehyde exposure (up to 12 weeks) induced a dose-dependent increase in Aβ40, Aβ42, APP, and phosphorylated tau levels in both wild-type and AD-mutant 3D cultures. These changes mimic hallmark features of AD neuropathology, suggesting that formaldehyde acts as a pathological driver in both sporadic and familial contexts. Our study provides direct evidence that chronic formaldehyde exposure may initiate and accelerate amyloid and tau pathologies in 3D human neural cell models.

Here, we exposed human macrophages to polystyrene nanoplastics (PS-NPs) and observed that PS-NPs induced the accumulation of lysosomes within the cells and lead to an increase in their contents. Additionally, PS-NPs co-localized with lysosomes and triggered lysosomal activation. Using a previously established method for PS-NPs adsorption to intracellular proteins and employing proteomic and bioinformatic approaches, we confirmed that after entering the cell, PS-NPs predominantly adsorbed proteins related to the lysosomal pathway, and stably adsorbed the key lysosomal protein cathepsin D (CTSD). Further studies identified that PS-NPs induced lysosomal exocytosis, during which the lysosomal-specific mature-CTSD adsorbed onto PS-NPs and was co-released from the cell.

We completed a pilot study using novel reverse-engineered EEN (RE-EEN), a whole food smoothie in place of commercial liquid formula (EEN) which contains food additives to improve shelf stability and palatability. In a four week trial with RE-EEN, we reported 80% of patients went into clinical remission after four weeks. We hypothesized RE-EEN would decrease environmental toxin exposure through reduction of processing food intake. Biosamples were collected at baseline and at weeks two, four, and eight during the RE-EEN study. Urinary heavy metals were analyzed by inductively coupled plasma mass spectrometry, and urinary phthalate metabolites and melamine by liquid chromatography with tandem mass spectrometry. For our primary analysis, change in baseline was calculated using a paired t-test for week four. Analysis was also completed for all weeks on RE-EEN using a generalized least squares model. Results were expressed as fold change ± standard error mean. Paired t-testing demonstrated a statistically significant (p<0.05) effect on molybdenum (Mo) with a fold change of 0.17 ± 0.15, an 83% reduction following RE-EEN treatment. Our results suggested an effect of arsenic (As) with fold change of 0.23 ± 0.26 (p=0.12), a 77% reduction following RE-EEN treatment. Our results also suggested an effect of cobalt (Co) with a fold change of 3.12 ± 3.12 fold, a 212% increase following RE-EEN therapy (p=0.16). With inclusion of all weeks on RE-EEN, Mo and As were statistically significant (p<0.05). Overall, we observed favorable shifts in urinary heavy metals by week four, and no effects were suggested in phthalate and melamine analysis. We saw increased precision in a sensitivity analysis when including all weeks for treatment. This is the first study to examine environmental toxicants in relation to whole foods smoothie diet in pediatric CD. RE-EEN dietary intervention shows promise in reducing chemical exposures and may contribute to CD remission. Notable limitations to this research include small sample size and absence of a control group.

The extensive utilization of additives and the presence of contaminants in food has raised concerns regarding the GM. Chemical compounds such as pesticides, potentially toxic elements, microplastics, antibiotics, and certain food additives (e.g., emulsifiers, sweeteners, preservatives) have been shown to disrupt the GM's composition, leading to gut dysbiosis with subsequent adverse health effects. The complex mechanisms through which these substances affect microbiota lack a thorough understanding, although animal studies have provided new insights into the dysbiosis caused by these substances in the GM. This review aims to comprehensively explore the interaction of food additives and contaminants with the equilibrium of GM, with strong emphasis on their influence on gut health. We outline these substances as causing inflammation, gastrointestinal injury, altered short-chain fatty acids and polyamines' synthesis, higher expression of pro-inflammatory cytokines, and hepatic lipid metabolic disorders.

DON disrupts intestinal barrier integrity, alters microbiota composition, promotes hepatic inflammation and apoptosis, and can impair neurochemical balance via direct and gut-mediated pathways. We also summarize the prevalence of DON contamination globally, with detection rates exceeding 60 % in some regions. In response to these risks, various mitigation strategies have been explored. This review evaluates the efficacy and safety of bioactive compounds such as vitamins, plant polyphenols, probiotics, and yeast derivatives, as well as synthetic agents, in reducing DON toxicity. Mechanisms of action include antioxidant defense, mycotoxin binding, and modulation of host immunity.
