Co-delivery Of mRNA Vaccines

Co-delivery Of mRNA Vaccines

A variety of mRNA delivery methods have been developed, such as direct injection of naked mRNA, lipid-based carriers, polymers and protein derivatives.  Despite the recent advances in mRNA vaccines, there is growing interest in developing improved safety and effective delivery methods for mRNA-based therapies, such as co-delivery of mRNA vaccines using adjuvants. Seattle Genova is a biotechnology corporation that specialize in providing mRNA delivery methods and associated merchandise that will help you make sure the protection of your biological products. Seattle Genova's state-of-the-art equipment, advanced technology and exceedingly skilled staffs are available to offer you with methods for mRNA delivery offerings. Seattle Genova’s purpose is to offer you with the maximum affordable, splendid offerings to make sure your satisfaction in a timely and professional manner.


The liposome-based delivery system allows the systemic delivery and transfection of mRNA, incorporating an adjuvant that is non-lipid like remains challenging, despite the fact that the co-delivery of mRNA (antigen) and effective adjuvant is fundamental to the activation of the cytotoxic T cells. This is due to the fact the presence of an adjuvant is essential for dendritic cell maturation (another necessity for cytotoxic T cell activation). Immunostimulatory molecular adjuvants such as stimulator of interferon genes (STING) agonists, Toll-like receptor (TLR) agonists, cytokines, and co-stimulatory ligands can activate APCs, enhancing antigen presentation to T cells and further desirable immune responses. For an instance, the co-delivery of mRNA and gardiquimod led to the effective antigen expression and DC maturation in vitro. The intravenous administration of the hybrid nanovaccine resulted in the enrichment of mRNA expression in the spleen and a strong immune reaction in vivo. The simultaneous delivery of the antigen and adjuvant both spatially and temporally through the core/shell nanoparticle service is discovered to be useful for tumor growth inhibition.
