METHOD OF PREPARING A TREATMENT PRODUCT, TREATMENT PRODUCT AND A PLASMID CONSTRUCT

摘要

The method of the invention for preparing a treatment product is characterized by using a starting plasmid based on a virus belonging to the Togaviridae stock from which the genes encoding capsid proteins of the virus have been deleted. An RNA io encoding virus-like particles VLP-RNA is prepared by manipulating the starting plasmid by connecting to it a spreading enabling gene and a treatment gene. The invention is furthermore concerned with such a treatment product and a plasmid construct encoding virus-like particles, which is prepared from the Sindbis virus in which the capsid protein of the virus has been substituted by a spreading enabling gene and a treatment gene.
