[ 1 ] - Ginger extract modulates the expression of IL-12 and TGF-β in the central nervous system and serum of mice with experimental autoimmune encephalomyelitis
Objective: The main function of IL-12 is differentiation of naive T cells intoTh1 cells and TGF-β is a powerful immunoregulatory cytokine. The immunomodulatory and anti-inflammatory properties of ginger have also been reported in some studies. The aim of this study was to evaluate the effects of ginger extract on the expression of IL-12 and TGF-β in a model of experimental autoimmune encephalom...
[ 2 ] - Whole Tumor Cell Vaccine Adjuvants: Comparing IL-12 to IL-2 and IL-15
Cancer immunotherapy (passive or active) involves treatments which promote the ability of the immune system to fight tumor cells. Several types of immunotherapeutic agents, such as monoclonal antibodies, immune checkpoint inhibitors, non-specific immunomodulatory agents, and cancer vaccines are currently under intensive investigation in preclinical and clinical trials. Cancer vaccines induce pe...
[ 3 ] - Ginger Extract Reduces the Expression of IL-17 and IL-23 in the Seraand Central Nervous System of EAEMice
Background: IL-17/IL-23 axis plays an important role in the pathogenesis of several autoimmune diseases such as experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS). The immunomodulatory properties of ginger are reported in previous studies. Objective: To evaluate the effects of ginger extract on the expression of IL-17 and IL-23 in a model of EAE. Methods: EAE was induc...
[ 4 ] - Vitamin D Modulates the Expression of IL-27 and IL-33 in the Central Nervous System in Experimental Autoimmune Encephalomyelitis
Background: It has been reported that vitamin D has broad anti-inflammatory and immunomodulatory effects. Objective: To evaluate the effects of vitamin D on the expression of IL-27 and IL-33 in a model of experimental autoimmune encephalomyelitis (EAE). Methods: EAE was induced in C57BL/6 mice by immunization with myelin oligodendroglial glycoprotein mixed with complete Freund's adjuvant. The m...
[ 5 ] - High Serum Levels of Rheumatoid Factor and Anti-Phosphatidylserine Antibody in Patients with Ischemic Heart Disease
Background: Immunopathological and inflammatory processes play important roles in the initiation and development of Ischemic Heart Disease (IHD). Objective: The aim of this study was to evaluate the serum levels of several autoantibodies including rheumatoid factor (RF), anti-nuclear antibodies (ANA), anti-small nuclear ribonucleoprotein (anti-Sm), anti-phosphatidylserine (anti-PS) and anti-car...
[ 6 ] - Impact of Opium on the Serum Levels of TGF-β in Diabetic, Addicted and Addicted-Diabetic Rats
Background: Several cells of immune system such as regulatory T cells and macrophages secrete transforming growth factor-β (TGF-β) in response to different stimuli. This cytokine has inhibitory effect on immune system and diminished production of this cytokine is associated with autoimmune disorders. Objective: The aim of this study was to evaluate the influence of opium addiction on serum leve...
[ 7 ] - High Sensitivity C–Reactive Protein and Im-munoglobulin G against Chlamydia Pneumo-niae and Chlamydial Heat Shock Protein-60 in Ischemic Heart Disease
Background: Inflammation and infectious agents such as Chlamydia pneumoniae have been associated with cardiovascular disease. Objective: To evaluate the serum high sensitivity C - reactive protein (hs-CRP) and antibodies against Chlamydia pneumoniae and Chlamydial heat shock protein-60 (Cp-HSP60) in patients with ischemic heart disease (IHD). Methods: 62 patients with IHD having either acute my...
[ 8 ] - Evaluation of Serum Interleukin-18 levels in Helicobacter Pylori-infected Peptic Ulcer Patients and its Association with Bacterial CagA Virulence Factor
Background: Helicobacter pylori infection is one of the most common gastrointestinal infections worldwide. Predominant T-helper 1 (Th1) responses with increased gamma interferon (IFN- γ) levels have been proposed to play an important role in H. pylori-induced peptic ulcer. However, bacterial factors contributing to the initiation of Th1 polarization of H. pylori-specific immune responses have n...
[ 9 ] - Differential Immunogenicity of A Recombinant Hepatitis B Vaccine in Iranian Neonates: Influence of Ethnicity and Environmental Factors
Objective: To compare immunogenicity of a recombinant hepatitis B (HB) vaccine in two groups of neonates born in two cities of Iran with different geographic and ethnic backgrounds. Materials and Methods: Ten micrograms of a recombinant HB vaccine was administered under field condition to Iranian healthy neonates at 0, 1.5 and 9 months intervals. The subjects consisted of two groups of 290 an...
[ 10 ] - The Modulatory Effects of Vitamin D on the Expression of IL-12 and TGF-β in the Spinal Cord and Serum of Mice with Experimental Autoimmune Encephalomyelitis
Background & objective The immunoregulatory effects of transforming growth factor (TGF)-βand interleukin-12 (IL-12) and immunomodulatory actions of vitamin D (VD) were reported in several studies. This study aims to evaluate VD effects on IL-12 and TGF-β expression in experimental autoimmune encephalomyelitis (EAE). Methods:</str...
[ 11 ] - مروری بر نقش زیرگروههای لنفوسیتهای T در پاتوژنز بیماری مولتیپل اسکلروزیس
Background and Objectives: Multiple sclerosis (MS) is an autoimmune neurodegenerative disease of the central nervous system (CNS). Although, the contribution of various cells such as B cells, CD8+ T cells, microglia/macrophages, dendritic cells, asterocytes and mast cells in the pathogenesis of MS have been demonstrated, however, it seems that autoreactive myelin specific CD4+ T cells pla...
[ 12 ] - بررسی تأثیر ویتامین D3 و عصاره زنجبیل بر علایم بالینی و شدت التهاب در بیماری آنسفالومیلیت خود ایمن تجربی
Background and Objective: The anti-inflammatory effects of the vitamin D and ginger have been demonstrated in some studies. The aim of this study was to evaluate the effects of vitamin D and ginger extract on the clinical symptoms and leukocyte infiltration of experimental autoimmune encephalomyelitis (EAE). Materials and Methods: For the induction of EAE, the (C57BL/6) were immunize...
[ 13 ] - Lower immunity to tetanus in cigarette smoker subjects
Background: Cigarette smoking has been linked with the suppression of immune responses and increased susceptibility to numerous infections in humans. Tetanus is also a major public health problem in many countries. The aim of the present study was to evaluate the serum levels of anti-tetanus toxin antibodies in c igarette smoking and healthy non-smoking people . Materials and M...
[ 14 ] - Lower Serum Levels of Antibodies against Tetanus Toxin in Patients with Hypothyroidism
Background: A fundamental duty of the immune system is to defend against infectious agents. Significant abnormalities were reported in immune parameters of hypothyroid and hyperthyroid patients. In this study, we aim to assess various quantities of antibodies against the tetanus toxin (anti-TT) in hypothyroid and hyperthyroid patients. Materials and Methods: Anti-TT levels were measured in se...
