ИСТИНА

The invention relates to nanotechnology, biotechnology, genetic engineering and medicine and makes it possible to produce nucleoprotein nanostructures which exhibit various properties useful for health care purposes. The invention offers a new method for producing nucleoprotein nanoparticles, which involves (a) providing an expression vector for directing nucleic acid synthesis in a plant cell; (b) providing at least one expression vector for directing the synthesis of a protein in a plant cell, which is capable of binding with nucleic acid and forming nanoparticles; (c) introducing said vectors into the plant cell; and (d) cultivating the plant cell in conditions that provide for the combined expression of said vectors in the cell and the assembly of a nucleoprotein nanoparticle. Nanoparticles produced according to this method are also disclosed. The invention makes it possible to produce nucleoprotein nanoparticles based on virions, pseudoverions or virus-like particles. The nanoparticles produced can also contain a functional section in the form of an antigen or a sequence that binds and inactivates a pathogen.
