Solid lipid Nanocarriers diffuse effectively through mucus and enter intestinal cells – but where is my peptide?

This study aimed to evaluate the potential of Hydrophobic Ion Pairing combined with Solid Lipid Nanoparticles (SLN) and Nanostructured Lipid Carriers (NLC) to improve peptide transport across the intestinal border using Caco-2 cell monolayers (enterocyte-like model) and Caco-2/HT29-MTX co-cultured monolayers (mucin-secreting model).
This study showed that hydrophobic ion pairing enabled high encapsulation efficiency of peptide in SLN and NLC. The lipid-based nanocarriers were highly internalized by Caco-2 cell monolayers and were able to cross the mucus barrier (Caco-2/HT29-MTX cell model). However, the peptide intestinal transport was limited by an extensive release from the carriers.

In this study the authors obtained solid lipid nanoparticles using high pressure homogeneization, in which leuprolide was included as an ion pair. The nanoparticles were shown to be internalized by Caco-2 and Caco-2/HT29-MTX cell monolayers.

In this study, the authors showed that combining an efficient solubilizer and penetration enhancer achieves a synergic effect which enhances the passive diffusion of LID HCl through the Strat-M membrane in this Franz cell model.

Labrasol® is an efficacious intestinal permeation enhancer across rat intestine: Ex vivo and in vivo rat studies

In this study Labrasol® ALFwas investigated as an intestinal permeation enhancer in isolated rat colonic mucosae in Ussing chamber and in rat in situ intestinal instillations.

Labrasol® ALF (4 and 8 mg/mL) enhanced the transport of the paracellular markers  across colonic mucosae. The enhancement was non-damaging, transient, and molecular weight-dependent.
