Provided are particles of nucleic acid origami structure encapsulated by at least twelve capsid units, compositions comprising the same and uses thereof for delivery of nucleic acids to target cells.

The present disclosure relates to fusion proteins for inducing immune response and treating cancer, and particularly to fusion proteins for use as an immunogenic enhancer for inducing humoral immune response and cell-mediated immune response.

A transkingdom platform for the delivery of therapeutics to target cells. The system maintains the export and uptake functions of Inv while modifying its targeting away from 1 integrin to other proteins expressed on the surface of target eukaryotic cells (i.e., a cell surface protein) or chemical moieties (i.e., a cell surface chemical moiety) expressed on the surface of a target eukaryotic cell by replacing D4 and D5 of Inv with a binding domain from a heterologous protein via genetic engineering. These heterologous proteins could be derived from bacterial, fungal, animal, or viral genomes. This engineering would result in the construction of a chimeric Inv protein in which D1-D3 (i.e., the non-binding domains) are fused in frame to an alternative binding domain derived from a heterologous protein. The alternative binding domain would interact with a different cell surface protein or chemical moiety, which can in some instances be referred to as a receptor, on the surface on the surface of a eukaryotic cell, thereby allowing specific targeting to cells independent of Inv's intrinsic 1 integrin binding.
