Immunologic and pathologic characterization of a novel swine biomedical research model for eosinophilic esophagitis

FRONTIERS IN ALLERGY, 3.

By: L. Cortes n, D. Brodsky n, C. Chen, T. Pridgen n, J. Odle n, D. Snider n, G. Cruse n, A. Putikova* ...

author keywords: pig; food allergy; animal model; immunology; gastrointestinal; eosinophilic esophagitis
TL;DR: Swine is established as a relevant large animal model for translational biomedical research in EoE with the potential to facilitate development of therapeutics and it is demonstrated that the sensitization and oral challenge protocol not only induces the underlying immune markers but also the micro- and macro-pathological hallmarks of human EiE.

Steroid Eluting Esophageal-Targeted Drug Delivery Devices for Treatment of Eosinophilic Esophagitis

POLYMERS, 13(4).

By: A. Prasher n, R. Shrivastava n, D. Dahl n, P. Sharma-Huynh*, P. Maturavongsadit n, T. Pridgen n, A. Schorzman*, W. Zamboni* ...

author keywords: eosinophilic esophagitis (EoE); esophageal drug delivery systems; drug-eluting string; 3D printing; photopolymerizable resins; Drug loading strategies; steroids; fluticasone
TL;DR: Two novel esophageal-specific drug delivery platforms are reported, including a fluticasone-eluting string that could be swallowed similar to the string test “entero-test” and used for overnight treatment, and a 3D printed ring for local and sustained release of flutic asone in the esophagus.

A Glial Cell Inhibitor Blocks Epithelial Barrier Repair in a Pig Model of Intestinal Ischemia

Sheridan, A., Pridgen, T., Odle, J., Van Landeghem, L., Blikslager, A., & Ziegler, A. (2020, April). FASEB JOURNAL, Vol. 34.

By: A. Sheridan*, T. Pridgen*, J. Odle*, L. Van Landeghem*, A. Blikslager* & A. Ziegler*

TL;DR: It is hypothesized that EGC inhibition in juveniles will block epithelial barrier repair after ischemic injury mimicking the neonatal phenotype, and the development of glial‐epithelial crosstalk in barrier repair will ultimately guide novel clinical solutions to improve outcomes in neonatal patients affected by intestinal injury.

Epithelial restitution defect in neonatal jejunum is rescued by juvenile mucosal homogenate in a pig model of intestinal ischemic injury and repair

PLOS ONE, 13(8), e0200674.

By: A. Ziegler n, T. Pridgen n, J. Mills n, L. Gonzalez n, L. Van Landeghem n, J. Odle n, A. Blikslager n

Ductular and proliferative response of esophageal submucosal glands in a porcine model of esophageal injury and repair

American Journal of Physiology-Gastrointestinal and Liver Physiology, 313(3), G180–G191.

By: L. Krüger n, L. Gonzalez n, T. Pridgen n, S. McCall*, R. Furstenberg*, I. Harnden*, G. Carnighan n, A. Cox n ...
