HTLV-1 causes adult T-cell leukemia (ATL) and HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). Recombinant envelope glycoprotein is used in production of diagnostic enzyme-linked immunosorbent assay (ELISA) kit. There are some reports that a significant percentage of Iranian HTLV-1 infected patients showed no seroreactivity with MTA-1 peptide, while HTLV-1 had been confirmed...
Abstract Background and objective: Hepcidin is a cystein-rich antimicrobial peptide, which is secreted by the liver. It fights against wide spectrum of bacteria, viruses and fungi and it is a major regulator of iron homeostasis. Today, scientists have made many efforts on the production of hepcidin. Baculovirus expression system is one of the best eukaryotic expression systems for production of...
the green fluorescent protein (gfp) was originally isolated from the jellyfish aequorea victoria that fluoresces green when exposed to blue light. gfp protein is composed of 238 amino acids with the molecular mass of 26.9 kd. the gfp gene is frequently used in cellular and molecular biology as a reporter gene. to date, many bacterial, yeast , fungal, plants, fly and mammalian cells, including h...
there are two different co-expression systems including bicistronic; dual-vector or two-promoter to express two different genes simultaneously and also to study protein-protein interactions. bicistronic system has disadvantages e.g. compared with two-promoter system. in this paper, a simple method based on spliced overlap extension by polymerase chain reaction (soe-pcr) technique was demonstrat...
BACKGROUND Many biotechnological and industrial applications can benefit from cold-adapted EglCs through increased efficiency of catalytic processes at low temperature. In our previous study, Citrobacter farmeri A1 which was isolated from a wood-inhabiting termite Reticulitermes labralis could secrete a cold-adapted EglC. However, its EglC was difficult to purify for enzymatic properties detect...
Interleukin (IL)-13 plays an important role in the pathogenesis of asthma. A polymorphic variant of human IL-13 R130Q, results in substitution of an arginine with a glutamine was shown to be associated with asthma in Chinese Han nationality. We examined the functional consequences of this variant in vitro to investigate whether this variant enhanced functional activity compared with wild type I...
objective: today, aids is considered as a global problem and many efforts to generate an effective vaccine against this disease have been made, but remain inconclusive. dna vaccines are a member of the new generation of vaccines that can efficiently stimulate the immune system. however, recent findings indicate low immunogenicity for these vaccines and it is believed that these types of vaccine...
Background & Aims: Pseudomonas aeruginosa is an opportunistic pathogen and most important cause of hospital infections, which causes septicemia and death through various virulence factors such as exotoxin A. In the present study, P. aeruginosa exotoxin A (as a toxic factor) was prepared with the aim of obtaining a new recombinant vaccine candidate and conjugated with gold nanoparticles and its ...
Background and Aims: DNA constructs containing HCV antigens have become one of the vaccine candidates for induction of anti-HCV cellular and humoral immunity. In this study, we constructed a novel expressing vector harboring a fusion sequence derived from an overlapping fragment in the middle of NS3 and a truncated core fragment to avoid troubles reported to be associated with full gene express...
Background: Vaccines have played a special role in controlling and reducing mortality from infectious diseases. In this regard, DNA vaccines were developed to ease the production and reduce the risks of traditional vaccines. Human papillomavirus (HPV) has been introduced as the causing agent of cervical cancer. The capsid protein (L1) of HPV has been used to produce subunit and DNA vaccines. Th...
