topical and transdermal drug delivery systems are noninvasive and can be self-administered with the minimization of side-effects, have received increased attention during the past few years. nanoemulsions, emulsions sized between 20-200 nm with narrow distributions, offer several advantages for topical and transdermal delivery of pharmaceutical agents including controlled droplet size, the abil...
Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in CFTR genes that affect chloride ion channel. The CF is a good nominee for gene therapy as the asymptomatic carriers are phenotypically normal, and the desired cells are accessible for vector delivery. Gene therapy shows promising effects involving the correction of gene or replacement of the mutant gene with the func...
Novel, double-chained pyridinium compounds have been developed that display highly efficient DNA transfection properties. The transfection efficiency of several of these compounds is enhanced by an order of magnitude, when compared with the transfection efficiency accomplished with the widely used cationic lipid system, lipofectin. Most importantly, the pyridinium compounds were found to be ess...
Pneumonic plague, caused by inhalation of Yersinia pestis, represents a major bioterrorism threat for which no vaccine is available. Based on the knowledge that genetic delivery of monoclonal antibodies (MAbs) with adenovirus (Ad) gene transfer vectors results in rapid, high-level antibody expression, we evaluated the hypothesis that Ad-mediated delivery of a neutralizing antibody directed agai...
The histidine-rich amphipathic peptide LAH4 has antibiotic and DNA delivery capabilities. The peptide has a strong affinity for anionic lipids found in the outer membrane of bacterial membranes. A role for anionic lipids in release of cationic plasmid-containing complexes has been proposed previously, and disruption of membrane asymmetry and presentation of phosphatidylserine (PS) in the membra...
Background: Non-viral Nano carriers such as liposomes and cationic polymers based on engineered properties are regarded in gene delivery field. Although these carriers do not have weaknesses of viral vectors, but they are less efficient than viruses and they still need to be improved as favorable gene delivery carriers. Amongst non-viral carriers, cationic liposomes have been proposed for clini...
background: dendritic cells (dcs) are ideal accessory cells in the field of gene therapy. delivery of dna and sirna into mammalian cells is a useful technique in treating various diseases caused by single gene defects. selective gene silencing by small interfering rnas (sirnas) and antisense oligodeoxynucleotides (odn)s is an efficient method for the manipulation of cellular functions. an effic...
Objective(s): Breast cancer is the second leading cause of cancer death in females. Understanding molecular mechanisms in cancer cells compared with normal cells is crucial for diagnostic and therapeutic strategies. Long intergenic non-protein coding RNA, a regulator of reprogramming (lincRNA-RoR) is a noncoding RNA which initially was detected in induced pluripotent s...
Gene therapy as a modern therapeutic approach has not yet advanced to a globally-approved therapeutic approach. Lack of adequate reliable gene delivery system seems to be one of the major reasons from the pharmaceutical biotechnology point of view. Main obstacles delaying successful application of human gene therapy are presented in this review. The unique advantages of non-biological gene carr...
several species of magnetotactic bacteria have been discovered recently. these bacteria synthesize intracellular magnetic nanoparticles in specific sizes and shapes and arrange them in chains. these particles called magnetosomes and can be used for drug-delivery, cell-targeting and hyperthermia. magnetotactic bacteria navigate along the magnetic field; this process is known as ‘magnetotaxis’ wh...
