Liposomes for Immune Activation
Background Liposome-based Vaccine Services Platforms Advantages Related Services FAQs Resources
Liposomes are crucial lipid-based carriers with high biocompatibility and customizable designs, essential in advancing subunit and mRNA vaccine research. Known for enhancing immune activation, they play a key role in antigen delivery and adjuvant development. Creative Biolabs has established both drug delivery platform and vaccine platform, and combined the two to form a lipid-based drug delivery system in vaccines. By harnessing liposomes' potential, we support cutting-edge vaccine research
with unmatched precision and reliability.
Background of Liposome-based Immune Activation
Classical vaccines are generally whole killed or attenuated pathogens. In recent years, subunit vaccines are attracting extensive attention due to the advantages of better defined, easier to produce, and safer. These vaccines are produced based on well-characterized
antigens, such as recombinant proteins and peptides. However, their immunogenicity is not strong enough to induce the maturation of dendritic cells (DCs) due to their synthetic nature, and thus often leads to a weak immune response. Nanoparticulate
carriers such as liposomes can act as adjuvants for the enhancement of antigen delivery or activation of the innate immune response. The mechanisms by which liposomes enhance immune response include:
-
Antigen delivery, liposomes can help penetrate the tissues and access the lymphatics.
-
Depot effects, improved stability and sustained release of vaccine antigens.
-
Repetitive antigen display, facilitate B-cell receptor coaggregation, triggering, and activation.
-
Cross presentation, leakage of antigens into the cytosol may lead to the activation of major histocompatibility type I (MHC-I) pathways.

of immune responses.
