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...

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...

Stroke is one of the most leading causes of death and disability in the world. Complement system activation contributes to pathogenesis and neuronal damage following stroke. There are no defined biological serum markers to determine the severity of stroke in acute phases. The purpose of current study was to determine the association of three complement activators, namely Pentraxin-3 (PTX3),M-ficolin, and Surfactant protein A (SPA) with the severity of ischemic stroke. This cross-sectional study was done on 82 patients diagnosed with ischemic stroke at 24-96 hours of initiation of the clinical symptoms during 2014-2015...

Rheumatoid arthritis (RA) is a chronic autoimmune disease, which can lead to joint destruction and disability. Pannus formation due to chronic synovitis is the hallmark of RA. Oxidative stress as a consequence of immune cell activation and disease-modifying anti-rheumatic drugs can prevent inflammation and tissue destruction. Silymarin, an antioxidant extract from Silybum marianum, has been traditionally used for the treatment of liver diseases for decades. In the present non-randomized single-arm clinical trial (NRSACT) study we evaluated the effects of silymarin tablet (Livergol®) on inflammatory markers in stable RA patients...
