Pharmacokinetics and Biodistribution Analysis of Small Interference RNA for Silencing Tissue Transglutaminase-2 in Celiac Disease After Oral Administration in Mice Using Gelatin-Based Multicompartmental Delivery Systems.

ABSTRACT: Background: RNA interference (RNAi) therapy has tremendous potential in treating diseases that are characterized by overexpression of genes. However, the biggest challenge to utilize the therapy is to engineer delivery systems that can efficiently transport small interfering RNA (siRNA) to appropriate target sites. Our objective in this study was to develop and evaluate multi-compartmental systems for the oral delivery of siRNA that targets the overexpressed TG2 gene (TG2-siRNA) in the small intestine for the treatment of celiac disease (CD). Materials and Methods: Two types of multicompartmental systems were developed and evaluated: (1) a solid-in-solid multicompartmental system featuring "nanoparticle in microsphere oral system (NiMOS)" where type B gelatin na
