Selective Uptake Into Inflamed Human Intestinal Tissue and Immune Cell Targeting by Wormlike Polymer Micelles.
Gardey et al., Small 2023
DOI: 10.1002/smll.202306482
Key Findings:
- Three nanostructures (vesicles, spheres, and wormlike micelles) were created from the same block copolymer (PBA-b-PEO) to study their mucosal penetration in IBD.
- An Ussing chamber technique was used for ex vivo experiments on human colonic biopsies.
- Wormlike micelles selectively penetrated inflamed mucosa in IBD patients, with minimal uptake in healthy tissue.
- Spheres and vesicles either penetrated both inflamed and healthy tissues or none at all.
- Quantitative image analysis showed wormlike nanoparticles mainly localized within immune cells.
Importance:
This research highlights the significance of nanoparticle shape in targeted drug delivery for IBD treatment. The ability of wormlike micelles to selectively enter inflamed mucosa and localize within immune cells presents a promising strategy for enhancing the efficacy of IBD therapies while minimizing side effects.
Contribution to Literature:
The study provides novel insights into the role of nanoparticle shape in tissue selectivity, emphasizing the potential of wormlike nanoparticles for targeted therapy in IBD, a chronic disease lacking causal therapeutic options.
