A nucleoside-modified messenger RNA (modRNA) is a synthetic messenger RNA (mRNA) in which some nucleosides are replaced by other naturally modified nucleosides or by synthetic nucleoside analogues. [ 1 ] modRNA is used to induce the production of a desired protein in certain cells. An important application is the development of mRNA vaccines ...
A DNA vaccine is a type of vaccine that transfects a specific antigen -coding DNA sequence into the cells of an organism as a mechanism to induce an immune response. [1][2] DNA vaccines work by injecting genetically engineered plasmid containing the DNA sequence encoding the antigen (s) against which an immune response is sought, so the cells ...
How vectors work to transfer genetic material. Gene therapy utilizes the delivery of DNA into cells, which can be accomplished by several methods, summarized below. The two major classes of methods are those that use recombinant viruses (sometimes called biological nanoparticles or viral vectors) and those that use naked DNA or DNA complexes (non-viral methods).
SM-102 is a synthetic amino lipid which is used in combination with other lipids to form lipid nanoparticles. [1] These are used for the delivery of mRNA-based vaccines, [2][3][4] and in particular SM-102 forms part of the drug delivery system for the Moderna COVID-19 vaccine. [5][6][7] Lipid nanoparticles are an extension of earlier RNA ...
Gene delivery is the process of introducing foreign genetic material, such as DNA or RNA, into host cells. [1] Gene delivery must reach the genome of the host cell to induce gene expression. [2] Successful gene delivery requires the foreign gene delivery to remain stable within the host cell and can either integrate into the genome or replicate ...
An mRNA vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. [1] The vaccine delivers molecules of antigen -encoding mRNA into cells , which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen (such as a virus ) or by a ...
A subunit vaccine is a vaccine that contains purified parts of the pathogen that are antigenic, or necessary to elicit a protective immune response. [ 1 ] [ 2 ] Subunit vaccine can be made from dissembled viral particles in cell culture or recombinant DNA expression, [ 3 ] in which case it is a recombinant subunit vaccine .
Artificial gene synthesis, or simply gene synthesis, refers to a group of methods that are used in synthetic biology to construct and assemble genes from nucleotides de novo. Unlike DNA synthesis in living cells, artificial gene synthesis does not require template DNA, allowing virtually any DNA sequence to be synthesized in the laboratory.
