Autoimmunity represents the attack of the immune system of an organism against its own cells and tissues. Autoimmune diseases may affect one organ (Hashimoto thyroiditis) or can be systemic (chronic urticaria). Many factors are implicated in the pathogenesis of autoimmunity (white cells, cytokines, chemokines). Hashimoto thyroiditis has been associated with chronic urticaria in the last 3 decades in a number of clinical studies. Anti-thyroid antibodies have been documented in a proportion ranging from 10% to 30% in chronic urticaria patients in different countries from 3 continents...

This study aimed to explore the expression of T helper type 1 (Th1)/T helper type 2 (Th2) in herniated nucleus pulposus (NP) and determine their association with sciatic pain. NP was collected from 12 patients with lumbar disc herniation (LDH) (extrusion group) and 6 patients with a vertebral fracture (control group). The expression of Th1/Th2 and related cytokines in the NP was examined by flow cytometry, Western blot, and immunofluorescent staining. Subsequently, an LDH model was established in male Sprague-Dawley rats, and behavioral testings were carried out...

IL-33 and IL-37 (new cytokines of IL-1 family), soluble form of vascular endothelial growth factor receptor-2 (sVEGFR2) as well as membranous expression of VEGFR2 have some key roles in the pathogenesis of autoimmune and inflammatory diseases. The aim of this study was to correlate circulatory changes of these factors with the severity of multiple sclerosis (MS) as an autoimmune and inflammatory disease. Our case-control study was performed on 84 patients with MS and 75 healthy subjects. The serum levels of IL-33, IL-37 and sVEGFR2 in the peripheral blood samples of all participants were measured by enzyme-linked immune sorbent assay (ELISA)...

T-cell immunoglobulin and mucin domain (TIM)-3 have been shown to negatively regulate Th1 cell-mediated immunity. Activation of TIM-3 by galectin-9 induces Th1 cell apoptosis, which may contribute to skewing of immune response towards Th2-dominant immunity. The aim of this study was to determine whether certain genetic variations of TIM-3 influence predisposition to asthma in a sample of Iranian population. This case-control study was conducted on 209 patients with asthma and 200 healthy controls. The +4259 T>G and -574 G>T polymorphisms were detected using polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) and amplification refractory mutation system-PCR(ARMS-PCR)...

In Pakistan about 3.7% of the population is suffering from asthma, a chronic inflammatory disorder of airways. Asthma has wide spectrum of predisposing factors including environment and genetics. Many studies have been performed to determine association of asthma with serum IgE and major histocompatibility complex (MHC) alleles but conflicting results were reported. Therefore, present study was designed to determine frequency of HLA-DQβ1*0201 and DQβ1*0301 alleles in patients with bronchial asthma. This case control study included 85 asthmatic patients and 85 healthy controls...

Farmers are usually exposed to various inhaled allergens like pollens, mites, molds, and animal dander in their working environment which may lead to allergic rhinitis, asthma and urticaria. The purpose of this study was to identify sensitization to various aeroallergens in farmers and their occupational allergy symptoms. This cross sectional study included 103 male farmers and 100 non-farmer healthy controls. The work-related symptoms of farmers were recorded with a questionnaire. Spirometry and skin prick tests with 15 commercial allergen extracts were performed in both farmers and controls...

Current therapeutic approaches in allergic diseases especially asthma generally focus on using immunological strategies. According to the importance of FceRI in controlling allergic response we used two extracellular regions of Fc epsilon receptor I (FceRI) beta subunit peptides to design two peptide-based vaccines. Probably these peptides vaccines by triggering the immune response to FceRI can reduce the allergic symptoms through blocking the IgE specific receptor. Two extracellular parts of FceRI beta subunit were made by peptide synthesizer and conjugated with keyhole limpet Hemocyanin...

Inflammation is an important component of numerous cancers and chronic diseases and many inflammatory mediators have been shown to have potential prognostic roles. Tumor-infiltrating mast cells can promote tumor growth and angiogenesis, but the mechanism of mast cell activation is unclear. Early studies have shown that immunoglobulin free light chains (FLC) can trigger mast cell activation in an antigen-specific manner. Increased expression of FLC is observed within the stroma of many human cancers including those of breast, colon, lung, pancreas, kidney, and skin...

The abnormal function of the T lymphocytes causes a range of autoimmune diseases, particularly multiple sclerosis; hence, several methods have been used to treat these disorders through the induction of antigen-specific tolerance in T cells. The present study aims to use a simple and low-cost method to produce poly (lactic-co-glycolic acid) (PLGA) nanoparticles for carrying antigens and inducing antigen-specific tolerance. In this study, PLGA nanoparticles were produced using the water/oil/water (W/O/W) method...

After kidney transplantation, natural killer (NK) cells play a pivotal role in triggering the immune response to the allogeneic grafts primarily by their killer-cell immunoglobulin-like receptors (KIR). This process may be one mechanism that contributes to graft rejection. In this study, we have evaluated whether acute rejection after kidney transplantation was associated with predicted NK cell alloreactivity based on KIR gene and ligand along with KIR/HLA compound genotype analysis. After kidney transplantation, natural killer (NK) cells play a pivotal role in triggering the immune response to the allogeneic grafts primarily by their killer-cell immunoglobulin-like receptors (KIR)...

Regulatory T cells (Tregs) are important components of the immune system that modulate responses of other cells. These cells are involved in peripheral tolerance mechanisms, so defect in development and function of these cells can result in autoimmune disease. Increasing evidence supports the role of microRNAs-21 (miR-21) in the regulation of forkhead box P3 (Foxp3) expression in Tregs. We aimed to determine whether miR-21 transfection to naive CD4+ T cells can be useful in generation of iTregs in-vitro. We investigated in-vitro differentiation of miR-21-transfected naive CD4+ T cells to iTregs and compared these iTregs to cytokine-differentiated iTregs and control group...

Skin dryness and thickening are hallmarks of systemic sclerosis (SSc) disease. Aquaporins (AQPs) are plasma membrane proteins that transport glycerol and water, resulting in water retention and skin hydration. Expression of AQPs has been evaluated in human normal skin. However, expression of these proteins in SSc dermal fibroblasts has not yet been reported. The aim of this study was to assess the expression profile of AQPs in dermal fibroblasts of SSc patients. Fibroblast cells were extracted from SSc and healthy skin biopsies and characterized using fibroblast surface protein antibody...

Despite its proven efficacy, the hepatitis B vaccine requires improvements in immune enhancement and durability, especially in the elderly. Levamisole, an immune modulator, has been tested as an adjuvant to hepatitis B vaccine in several studies in immune-compromised populations. However, we aimed to evaluate the effect of levamisole on the immune response to hepatitis B vaccine in healthy subjects. In this randomized clinical trial, healthy family members of chronic hepatitis B patients were given twenty-microgram intramuscular injections of hepatitis B vaccine at 0, 1, and 6 months and 50 miligrams of oral  levamisole twice a day for two weeks with every vaccination dose...

Taking medical history, physical examination, and performing some in vivo and in vitro tests are necessary for the diagnosis of allergy. Skin prick test (SPT) is considered as the standard method and first-line approach for the detection of allergic sensitization. Although mainly SPT is used for the detection of allergic sensitization, intradermal skin test (IDST) may be necessary, especially in patients with a negative SPT result. IDST is quite safe; however, is nowadays seldom used for detection of inhalant allergy and its value remains controversial...
