Virus-inspired nucleic acid delivery system: Linking virus and viral mimicry.

چکیده
Targeted delivery of nucleic acids into disease sites of human body has been attempted for decades, but both viral and non-viral vectors are yet to meet our expectations. Safety concerns and low delivery efficiency are the main limitations of viral and non-viral vectors, respectively. The structure of viruses is both ordered and dynamic, and is believed to be the key for effective transfection. Detailed understanding of the physical properties of viruses, their interaction with cellular components, and responses towards cellular environments leading to transfection would inspire the development of safe and effective non-viral vectors. To this goal, this review systematically summarizes distinctive features of viruses that are implied for efficient nucleic acid delivery but not yet fully explored in current non-viral vectors. The assembly and disassembly of viral structures, presentation of viral ligands, and the subcellular targeting of viruses are emphasized. Moreover, we describe the current development of cationic material-based viral mimicry (CVM) and structural viral mimicry (SVM) in these aspects. In light of the discrepancy, we identify future opportunities for rational design of viral mimics for the efficient delivery of DNA and RNA.

Background: Despite of isolation of Xenotropic murine leukaemia virus-related virus (XMRV) from the patients acquired prostate cancer in 2006 and patients with chronic fatigue syndrome in 2009, there have been controversial findings about its potential role in human diseases and frequencies in different population groups. In the present study, we aimed to determine the frequency of XMRV genome ...
متن کاملInduction of Nucleic Acid Damage in Viral Genomes using Riboflavin in Combination with UV Light
Background and Aims: Despite the screening of blood donors, blood transfusion represents an ideal port of entry for blood-borne infection. Blood-borne pathogen transmission has been a concern since the earliest days of transfusion. The blood product of platelet (PLT) concentrates is still faced with the risk of bacterial and viral contaminations. Pathogen inactivation technologies offer a proac...

Enteroviruses are the causative agents of a number of diseases in humans. Group B coxsackieviruses are believed to be the most common viral agents responsible for human heart disease. Genomic data of enteroviruses has allowed developing new molecular approaches such as Nucleic Acid Sequence Based Amplification (NASBA) for detection of such viruses. In this study, coxsackievirus B3 (CVB3) was de...
