[ 1 ] - هورمون درمانی: راه کاری موثر در تنظیم پاسخ سلول های Th1 زنان مبتلا به آسم آلرژیک
Background: The pattern of incidence of asthma varies with age and sex, as females suffer more than males. Some asthmatic women report premenstrual exacerbation of asthma symptoms as well as variation of its severity during pregnancy, thus it is believed that sex hormonal changes could affect asthma. Hormone Replacement Therapy (HRT) is a routine and accepted procedure which is used for treatme...
[ 2 ] - Cloning, expression, and spectral analysis of mouse betatrophin
Background: Betatrophin, a novel secretory protein from liver and fatty tissues, is believed to be involved in lipid and glucose metabolism. However, its precise physiological role remains unclear. Here, we report the cloning, expression, and purification steps of mouse betatrophin in a prokaryotic system, followed by its structural analysis. Methods: Specific cloning primers were...
[ 3 ] - Fractionation and identification of the allergic proteins in Aspergillus species
Background and Purpose: Allergy is an undesired immune response to non-pathogenic agents. However, some opportunistic microorganisms such as fungi can also cause allergy. Among those fungi, hyphae form of Aspergillus strains including A. fumigatus, A. flavus, and A. niger could be mentioned. In this study, we aimed to separate allergic proteins from Aspergillus strains and determine their ident...
[ 4 ] - Effects of Oral Probiotic Feeding on Toll-Like Receptor Gene Expression of the Chicken’s Cecal Tonsil
Background: It was proposed that probiotics may influence immune system through direct or indirect exposure. Direct exposure is mostly mediated by surface receptors. Toll-like receptors (TLRs) are conserved molecular sensors which could be triggered via some pathogen associated structures, hence, modulate the immune responses. This study was conducted to elucidate the impact of lactobacillus ac...
[ 5 ] - Cloning, Expression, Purification and CD Analysis of Recombinant Human Betatrophin
Betatrophin is a member of the angiopoietin-like (ANGPTL) family that has been implicated in both triglyceride and glucose metabolism. The physiological functions and molecular targets of this protein remain largely unknown; hence, a purified available protein would aid study of the exact role of betatrophin in lipid or glucose metabolism. In this study, we cloned the full-length cDNA of betatr...
[ 6 ] - Induction of humoral immune responses and inhibition of metastasis in mice by a VEGF peptide-based vaccine
Objective(s): Blocking of vascular endothelial growth factor (VEGF) plays a pivotal role in inhibition of metastasis and is a target for development of anti-angiogenic agents. In this study, a peptide-based vaccine was designed and its potential for induction of humoral immune responses, generation of neutralizing antibodies, inhibition of tumor growth and metastasis w...
[ 7 ] - Incorporation of T-cell epitopes from tetanus and diphtheria toxoids into in-silico-designed hypoallergenic vaccine may enhance the protective immune response against allergens
Objective(s): New generation of allergy vaccines is capable of promoting the development of protective IgG and blocking the functionality of allergen-specific IgE. We incorporated universal and powerful T-cell epitopes from tetanus and diphtheria toxoids (TD epitope) into recombinant Che a 2, the well-known allergic profilin of Chenopodium album, to determine its immun...
[ 8 ] - Cloning and Expression of 2S Albumin As a Major Allergen of Persian Walnut
Background: Food hypersensitivity to walnut usually results in mild symptoms; however, several cases of anaphylactic reactions to this product have been observed. This study aimed to determine the immunochemical characteristics of the Persian walnut and provide the recombinant form of its main allergen. Materials and Methods: The allergenic proteins of th...
