Biomimetic nanovaccine-mediated multivalent IL-15 self-transpresentation (MIST) for potent and safe cancer immunotherapy

Oct 24, 2023

Wang et al. developed biomimetic nanovaccine with multivalent interleukin-15 self-transpresentation (biNV-IL-15) that allows spatiotemporal manipulation of therapeutic T cells, elicits broad spectrum antigen-specific T cell responses, and promotes cures in multiple syngeneic tumor models with minimal systemic side effects.

Materials engineering strategies for cancer vaccine adjuvant development

Materials engineering strategies for cancer vaccine adjuvant development

May 9, 2023

Zhang et al. outlined the current state of materials engineering strategies, including those based on molecular adjuvants, polymers/lipids, inorganic nanoparticles, and bio-derived materials, for adjuvant development. They also elaborate on how these engineering strategies and the physicochemical features of the materials involved influence the effects of adjuvants. Read more in Chemical Society Reviews.

Activatable NIR-II Photothermal Lipid Nanoparticles for Improved Messenger RNA Delivery

April 19, 2023

Li et al. presented second near-infrared (NIR-II) lipid nanoparticles (LNPs) containing pH activatable NIR-II dye conjugated lipid (Cy-lipid) for potentiating mRNA delivery efficiency via a stimulus-responsive photothermal-promoted endosomal escape delivery (SPEED) strategy.
