Introduction
Gene therapy is a means of treating or avoiding illness by modifying the genes within the body’s cells. Genes that aren’t functioning correctly could be to blame for the disorder.
By deleting a faulty gene or introducing a new gene, gene therapy seeks to cure disease or enhance the body’s ability to battle illness. Among other disorders, gene therapy carries the potential for the treatment of tumors, cystic fibrosis, cardiovascular disease, obesity, and hemophilia.
Gene therapy works by:
Substituting transformed genes
Anchoring transformed genes
Thus, increasing the visibility of infected cells to the body’s defense system. Putting it up, the endogenous genome is manipulated.
One of the problems related to gene-specific treatment is that the gene cannot be specifically imbibed into the cell’s nucleus. It requires a transporter or a conveyer (a vector).
Viruses have the property to recognised particular cells and pass DNA/RNA into the cells’ total sets of genes, due to which they are mainly used as carriers. The infected gene is replaced with the gene of interest in the virus.
When administered encapsulated or conjugated to the surface of nanoparticles, gene silencing therapeutics, siRNAs, have been shown to have slightly longer half-lives. In certain cases, these therapeutics are used to treat ‘undruggable’ cancer proteins. Furthermore, it has been shown that the improved stability of genetic therapies provided by nanocarriers, which is also paired with controlled release, prolongs their effects 1.
One of the challenges faced in gene therapy is delivering the gene to the right place and switching it on. As a consequence, gene therapy often necessitates a case-by-case approach. This could be beneficial, but it could also be very costly 2.
In today’s drug treatment, vast patient populations are treated as individuals, regardless of the possibility of human, genetically dependent variations in drug reaction. Pharmacogenomics, on the other hand, could be able to better target successful treatment to smaller patient subpopulations that, though sharing the same disease phenotype, have different genetic profiles. It’s also uncertain if this plan would result in successful, more cost-effective care 3,4,5.
Plasmids with the fundamental constituents of gene expression
One of the keys to effective gene therapy is selecting the best vector. There are several different types of vectors, both viral and...
