Abstract: Disclosed are lipid nanoparticle (LNP) delivery systems that specifically target T cells. The LNP delivery system comprises antibodies conjugated to the surface of the LNP, e.g., via maleimide chemistry, that target at least two T cell surface proteins, e.g., CD3 and CD28. The LNP delivery system can have a single population of LNP conjugated to either a bispecific antiCD3/antiCD28 antibody, or two monospecific antiCD3 and antiCD28 antibodies, or two populations of LNP wherein each population comprises a monospecific antibody. The payload of the LNP delivery system can be, e.g., mRNA encoding chimeric antigen receptors (CAR), a linear DNA fragment or a plasmid encoding chimeric antigen receptors (CAR) or therapeutic proteins such as antibodies, components of a gene editing systems (e.g., CRISPR-Cas), small molecules, antibody-drug conjugates (ADC), and any combination thereof, either encapsulated in the LNP or attached to its surface (e.g., conjugated).
