Changing killer CD8 T cells inside the body using fractalkine-linked mRNA nanoparticles
Updated
Abstract
Essence
Fractalkine-conjugated mRNA lipid nanoparticles enabled efficient transient in vivo mRNA delivery to cytotoxic effector CD8 T cells in mice and rhesus macaques.
Evidence
Preclinical delivery-platform study testing fractalkine-conjugated mRNA-LNP targeting and reporter or payload expression in CX3CR1-positive T cells in vitro, in mice, and in rhesus macaques.
Caveat
The results show targeting and transient engineered expression in animal models, not therapeutic benefit or long-term safety in humans.
