该研究揭示了当前肠道屏障功能评估体系存在的关键问题: Namely, the discrepancy between preclinical animal models and human clinical trials in terms of dose response relationships and temporal dynamics of barrier perturbation. This has direct implications for the evaluation of novel therapeutic agents targeting intestinal barrier integrity, particularly in the context of NSAID-induced enteropathy. The findings advocate for a more nuanced approach in studying barrier function, incorporating not only traditional biomarkers but also dynamic pharmacokinetic-pharmacodynamic (PK-PD) modeling and multi-omics analysis. This paradigm shift is essential for developing personalized therapies that address individual variability in barrier resilience and vulnerability.
