Lipid Nanoparticle: Beyond Delivery Vehicle—Unveiling Its Immunological Adjuvant Potential

Résumé fourni par la source

Lipid nanoparticles (LNPs) have extensively been used in drug delivery over the years, and the perspective of their significance has been well established. Latest findings have demonstrated the inherent adjuvant capacity of some specific lipid components, especially in stimulating immune compartments, which prompted the rational use of lipid-based delivery vehicles in drug R&D. In this concise review, we summarize current knowledge on the adjuvant properties of LNP, with a particular focus on the key components that mediate such effects. Specifically, we describe the vital role of ionizable lipids in triggering innate immune activation and inflammation and highlight the importance of these lipids in determining vaccine effectiveness or safety. Furthermore, the mechanisms by which LNP enhance the immune response are discussed in detail, shedding light on their potential applications in next-generation vaccine design and development. We also present compelling pre-clinical studies that serve as strong evidence for the adjuvant properties of LNP components in enhancing vaccine immunogenicity.
