Background: The MERS-CoV is a novel human coronavirus causing respiratory syndrome since April 2012. The replication of MERS-CoV is mediated by ORF 1ab and viral gene activity can be modulated by RNAi approach. The inhibition of virus replication has been documented in cell culture against multiple viruses by RNAi approach. Currently, very few siRNA against MERS-CoV have been computationally designed and published. Methods: In this review, we have discussed the computational designing and delivery of potential siRNAs. Potential siRNA can be designed to silence a desired gene by considering many factors like target site, specificity, length and nucleotide content of siRNA, removal of potential off-target sites, toxicity and immunogenic responses. The efficient delivery of siRNAs into targeted cells faces many challenges like enzymatic degradation and quick clearance through renal system. The siRNA can be delivered using transfection, electroporation and viral gene transfer. Currently, siRNAs delivery has been improved by using advanced nanotechnology like lipid nanoparticles, inorganic nanoparticles and polymeric nanoparticles. Conclusion: The efficacy of siRNA-based therapeutics has been used not only against many viral diseases but also against non-viral diseases, cancer, dominant genetic disorders, and autoimmune disease. This innovative technology has attracted researchers, academia and pharmaceuticals industries towards designing and development of highly effective and targeted disease therapy. By using this technology, effective and potential siRNAs can be designed, delivered and their efficacy with toxic effects and immunogenic responses can be tested against MERS-CoV.

Exploiting surface endocytosis receptors using carbohydrate-conjugated nanocarriers brings outstanding approaches to an efficient delivery towards a specific target. Macrophages are cells of innate immunity found throughout the body. Plasticity of macrophages is evidenced by alterations in phenotypic polarization in response to stimuli, and is associated with changes in effector molecules, receptor expression, and cytokine profile. M1-polarized macrophages are involved in pro-inflammatory responses while M2 macrophages are capable of anti-inflammatory response and tissue repair. Modulation of macrophages’ activation state is an effective approach for several disease therapies, mediated by carbohydrate-coated nanocarriers. In this review, polymeric nanocarriers targeting macrophages are described in terms of production methods and conjugation strategies, highlighting the role of mannose receptor in the polarization of macrophages, and targeting approaches for infectious diseases, cancer immunotherapy, and prevention. Translation of this nanomedicine approach still requires further elucidation of the interaction mechanism between nanocarriers and macrophages towards clinical applications.

Rapid developments in the field of plant genome editing using clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) systems necessitate more detailed consideration of the delivery of the CRISPR system into plants. Successful and safe editing of plant genomes is partly based on efficient delivery of the CRISPR system. Along with the use of plasmids and viral vectors as cargo material for genome editing, non-viral vectors have also been considered for delivery purposes. These non-viral vectors can be made of a variety of materials, including inorganic nanoparticles, carbon nanotubes, liposomes, and protein- and peptide-based nanoparticles, as well as nanoscale polymeric materials. They have a decreased immune response, an advantage over viral vectors, and offer additional flexibility in their design, allowing them to be functionalized and targeted to specific sites in a biological system with low cytotoxicity. This review is dedicated to describing the delivery methods of CRISPR system into plants with emphasis on the use of non-viral vectors.
