Oral administration of peptide and protein drugs faces a big challenge partly due to the hostile gastrointestinal (GI) environment. Lipid-based delivery systems are attractive because they offer some protection for peptides and proteins. In this context, we prepared a special lipid-based oral delivery system: archaeosomes, made of the polar lipid fraction E (PLFE) extracted from Sulfolobus acidocaldarius, and explored its potential as an oral drug delivery vehicle. Our study demonstrates that archaeosomes have superior stability in simulated GI fluids, and enable fluorescent labeled peptides to reside for longer periods in the GI tract after oral administration. Although archaeosomes have little effect on the transport of insulin across the Caco-2 cell monolayers, the in vivo experiments indicated that archaeosomes containing insulin induced lower levels of blood glucose than a conventional liposome formulation. These data indicate that archaeosomes could be a potential carrier for effective oral delivery of peptide drugs.
