Abstract
Infection with human immunodeficiency virus (HIV)-1 causes immunological disorders and death worldwide which needs to be further assisted by novel anti-retroviral drug delivery systems. Consequently, finding newer anti-retroviral pharmaceuticals by using biocompatible, biodegradable nanomaterials comprising a nanoparticle as core and a therapeutic agent is of high global interest. In this experiment, a second generation of a negatively charged nano-biopolymer linear globular G2 dendrimer was carefully conjugated and loaded with well-known anti-HIV drugs lamivudine and efavirenz, respectively. They were characterised by a variety of analytical methods such as Zetasizer, Fourier-transform infrared spectroscopy, elemental analysis and liquid chromatography-mass spectroscopy. Additionally, conjugated lamivudine and loaded efazirenz with globular PEGylated G2 dendrimer were tested on an HEK293 T cell infected by single-cycle replicable HIV-1 virion and evaluated using XTT test and HIV-1 P24 protein load. The results showed that lamivudine-conjugated G2 significantly decreased retroviral activity without any cell toxicity. This effect was more or less observed by efavirenz-loaded G2. These nano-constructs are strongly suggested for further in vivo anti-HIV assays.
期刊介绍：
Electrical and electronic engineers have a long and illustrious history of contributing new theories and technologies to the biomedical sciences. This includes the cable theory for understanding the transmission of electrical signals in nerve axons and muscle fibres; dielectric techniques that advanced the understanding of cell membrane structures and membrane ion channels; electron and atomic force microscopy for investigating cells at the molecular level.
Other engineering disciplines, along with contributions from the biological, chemical, materials and physical sciences, continue to provide groundbreaking contributions to this subject at the molecular and submolecular level. Our subject now extends from single molecule measurements using scanning probe techniques, through to interactions between cells and microstructures, micro- and nano-fluidics, and aspects of lab-on-chip technologies. The primary aim of IET Nanobiotechnology is to provide a vital resource for academic and industrial researchers operating in this exciting cross-disciplinary activity. We can only achieve this by publishing cutting edge research papers and expert review articles from the international engineering and scientific community. To attract such contributions we will exercise a commitment to our authors by ensuring that their manuscripts receive rapid constructive peer opinions and feedback across interdisciplinary boundaries.
IET Nanobiotechnology covers all aspects of research and emerging technologies including, but not limited to:
Fundamental theories and concepts applied to biomedical-related devices and methods at the micro- and nano-scale (including methods that employ electrokinetic, electrohydrodynamic, and optical trapping techniques)
Micromachining and microfabrication tools and techniques applied to the top-down approach to nanobiotechnology
Nanomachining and nanofabrication tools and techniques directed towards biomedical and biotechnological applications (e.g. applications of atomic force microscopy, scanning probe microscopy and related tools)
Colloid chemistry applied to nanobiotechnology (e.g. cosmetics, suntan lotions, bio-active nanoparticles)
Biosynthesis (also known as green synthesis) of nanoparticles; to be considered for publication, research papers in this area must be directed principally towards biomedical research and especially if they encompass in vivo models or proofs of concept. We welcome papers that are application-orientated or offer new concepts of substantial biomedical importance
Techniques for probing cell physiology, cell adhesion sites and cell-cell communication
Molecular self-assembly, including concepts of supramolecular chemistry, molecular recognition, and DNA nanotechnology
Societal issues such as health and the environment
Special issues. Call for papers:
