Biomimetic nanoparticles deliver mRNAs encoding costimulatory receptors and enhance T cell mediated cancer immunotherapy
Abstract
Antibodies targeting OX40 or CD137, two T cell costimulatory receptors, have been shown to improve antitumor immunity. Here the authors design a phospholipid-derived nanoparticle to deliver OX40 or CD137 mRNA to T cells in vivo, improving efficacy of anti-OX40 and anti-CD137 antibody therapy in preclinical tumor models.
