Gene delivery is the process of introducing foreign genetic material, such as DNA or RNA, into host cells. Gene delivery must reach the genome of the host cell to induce gene expression. Successful gene delivery requires the foreign gene delivery to remain stable within the host cell and can either integrate into the genome or replicate independently of it Liposomal gene delivery systems.

Almost two decades have passed since the first efforts to develop liposomes for the transfer and expression of extracellular RNA 1 and DNA into mammalian cells. 2-8 Efficient delivery of functional DNA into eucaryotic cells is highly desirable for adding missing or replacing defective genes in gene therapy. 9, 10. This leaves naked DNA administration, liposomal gene delivery, and virally mediated gene transfer as the methods of choice for in vivo gene therapy application. Injection of naked DNA plasmids has been shown to result in intracranial gene expression. 2 However, with current technology, expression efficiency is very low and the.

To achieve this goal, a number of hurdles are to be overcome by the gene delivery system. Transfection is affected by: (a) targeting the delivery system to the target cell, (b) transport through the cell membrane, (c) uptake and degradation in the endolysosomes and (d) intracellular trafficking of plasmid DNA to the nucleus. 2. NANOPARTICLE Gene delivery systems involve the use of several techniques for transfer of isolated genetic materials into a viable host cell. At present, there are two classes of delivery systems: biological and non-biological (which the latter includes physical and chemical) systems. Liposome-mediated gene delivery into plant cells. Physiol. Plant., 79. Plasmid DNA-encapsulating liposomes: effect of a spacer between the cationic head group and hydrophobic moieties of the lipids on gene expression efficiency. Yosuke Obata et al. Biochimica et biophysica acta, 1788(5), 1148-1158 (2009-03-03 A smart drug delivery system, as illustrated in Fig. 2, using liposomes as nanocarriers, consists of (i) smart nanocarriers which carry anti-cancer drugs to the cancer site, (ii) targeting mechanisms to locate the cancerous site and (iii) stimulus techniques to release the payloads at the pre-located cancer cell site. Eight nanocarriers as well. This delivery system can be loaded with several molecules of an anticancer drug, e.g., Taxol ® (Ashcroft et al., 2006).
