Archaeosomes

Archaeosomes are recognized as an exceptionally useful carrier system, adept at transporting a variety of cargoes to their intended destinations. As experience in the realm of lipid-based delivery systems grows, Creative Biolabs is at the cutting edge of advancing the development of archaeosomes. Our team of scientists is dedicated to providing clients with high-quality characterization and both in vitro and in vivo validation services for archaeosomes. This includes comprehensive support for the encapsulation efficiency, stability, and release profiles of various therapeutic agents within the archaeosomal structure, ensuring their potential in drug delivery systems is fully realized.

Archaeosomes

Archaeosomes are liposomal formulations that are prepared with one or more lipids, mainly containing diether and/or tetraether linkages, found in archaeobacterial membrane. These archaeobacterial lipids present unique features and higher stabilities to several conditions including high or low temperatures, high salinity, acidic media, anaerobic atmosphere, high pressure over conventional liposomes. The surprising stability of archaeosomes can be attributed to the following properties brought by the archaeobacterial lipids’ structure:

1. The ether linkages are more stable than esters over a wide range of pH.
2. The branching methyl groups help to reduce both crystallization and permeability.
3. The unusual stereochemistry of the glycerol backbone ensures the resistance of the membrane to enzymatic attack.
4. The bipolar lipids span the membranes and enhance their stability properties.

The biocompatibility and better stability of archaeosomes in numerous conditions offer advantages over conventional liposomes for their usage in biotechnology including vaccine and drug/gene delivery. Thus, archaeosomes can be considered as better carriers especially for protein and peptide delivery due to their high stability.

Applications of Archaeosomes

Archaeosomes induce strong CD4⁺ as well as CD8⁺ CTL responses to entrapped soluble antigens and thus have been used in self-adjuvanting drug delivery systems for cancer vaccines. Additionally, archaeosomes have also been widely used in other aspects of drug delivery. Since archaeosomes are a type of liposomes prepared from the polar lipids of various archaeobacteria, they may be used to deliver different types of cargoes such as gene, small fluorescent molecules, peptides, small proteins, large protein aggregates and natural antioxidant compounds into epithelial cells.
