In addition, although ultrasonic nebulization is widely used for airway inflammatory diseases, including pulmonary disorders and asthma, its application in AR has received limited attention. <b>Methods:</b> ADELNs were isolated by differential centrifugation and ultracentrifugation and characterized using transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), dynamic light scattering (DLS), thin-layer chromatography (TLC), SDS-PAGE, and agarose gel electrophoresis. To evaluate the effects of ultrasonic nebulized ADELNs on AR, we designed and validated a mouse nasal nebulization device. Cellular inflammation and OVA-induced AR mouse models were then established, and inflammatory and pathological indicators were assessed using ELISA, RT-qPCR, histological staining, and related assays. Western blotting was used to investigate the involvement of the NF-κB signaling pathway. <b>Result:</b> ADELNs were successfully isolated and exhibited typical exosome-like characteristics. The ultrasonic nebulization device showed good stability. Nebulized ADELNs alleviated AR symptoms in mice in a concentration-dependent manner, reduced inflammatory cytokines, serum histamine, and OVA-specific IgE, downregulated inflammatory cytokine mRNA expression in the nasal mucosa, improved nasal mucosal thickness, and decreased mast cell infiltration. To explore the potential mechanism, ADELN treatment was associated with reduced IκB and p65 phosphorylation and decreased NF-κB nuclear translocation, suggesting that modulation of NF-κB signaling may contribute to the anti-inflammatory effects of ADELNs. <b>Conclusions:</b> This study successfully isolated and characterized ADELNs. Using a self-designed ultrasonic nebulization device for mouse nasal delivery, we showed that ADELNs inhibited cellular inflammation in vitro, alleviated symptoms and pathological injury in AR mice, and may exert anti-AR effects by suppressing the NF-κB signaling pathway.

NP-011 is a truncated recombinant human milk fat globule EGF factor 8 protein developed for the treatment of MASH-associated liver fibrosis. This study extrapolated the pharmacokinetics of NP-011 from animals to humans and retrospectively evaluated the predictions using Phase I clinical data. <b>Methods:</b> Population pharmacokinetic models were developed using plasma concentration-time data following the intravenous administration of NP-011 in mice, rats, and monkeys. Model performance was evaluated using goodness-of-fit diagnostics, visual predictive checks, and nonparametric bootstrap analyses. The human pharmacokinetic parameters were predicted using simple allometric scaling. The maximum lifespan potential-corrected scaling was evaluated as a supplementary sensitivity analysis. Predicted human concentration-time profiles and exposure parameters were retrospectively compared with observed data from the single ascending dose component of the Phase I data. The Phase I study was registered at ClinicalTrials.gov (NCT05387499). <b>Results:</b> A two-compartment model with first-order elimination described NP-011 pharmacokinetics in all three species.

However, the systematic overprediction of exposure and limited coverage of the simulated prediction intervals indicate that these predictions should be interpreted cautiously.
