Table 2 Recommendations for future research
Recommendation
Specific approach (key points)
Longitudinal single-cell profiling(1) Time points (post AP induction): Early (2 hours, 6 hours, and 24 hours), mid (3 days and 7 days) and late (14 days and 28 days); and (2) Assays: FITC-dextran permeability and serum LPS (barrier); histological score and IHC/FACS for neutrophil/macrophage infiltration along with IL-6/TGF-β (inflammation); Masson’s staining and Col1a1/Col3a1 mRNA (fibrosis); and 16S rRNA sequencing (microbiome recovery)
MC activation mechanisms(1) Techniques: scATAC-seq + phospho-proteomics on sorted MCs; and (2) Targets: PAR2/tryptase, the FcεRI-independent pathway, and NF-κB/AP-1
Human spatial validation(1) Samples: Ileal/jejunal biopsies (Ranson < 3 vs ≥ 3); (2) Platform: 10 × Visium or GeoMX DSP; and (3) Readouts: MC density, CCL5, and immune infiltrates
Preclinical intervention studies(1) Drugs: Cromolyn sodium and Maraviroc; and (2) Endpoints: Gut histology, 16S rRNA, cytokines, and 72 hours survival
