[ 2 ] - ADAM33 gene polymorphisms in Southwestern Iranian patients with asthma
Objective(s): Asthma, the most frequent chronic respiratory disease, results from a complex interaction between multiple genes and environmental factors. To date, more than 100 candidate genes and single nucleotide polymorphisms (SNPs) have been reported to be associated with asthma. One of the discovered genes related to asthma is ADAM33. However, the relationship between ADAM33 gene polymorph...

[ 4 ] - Natural Killer Cell Cytotoxicity Against SKOV3 after HLA-G Downregulation by shRNA
Background: HLA-G is a nonclassical HLA class I molecule which, when elevated in tumor cells, is one of the main factors involved in tumor evasion of immune responses including NK and T cells. Objective: To evaluate the effect of HLA-G downregulation on NK cell cytotoxicity in tumor cell lines. Methods: The expression level of HLA-G was measured by real-time PCR and flowcytometry after transfec...
[ 5 ] - Effect of Thermal Stress on MICA/B Induction in a Human Liposarcoma Cell Line
Background: A possible mechanism by which hyperthermia enhances tumor immunogenicity is the induction of NKG2D ligands on tumor cells. Although the expression of MHC class I chain-related protein A and B (MICA/B) has previously been reported in different carcinomas, there is no information about MICA/B expression in liposarcomas. Objective: To investigate MICA/B induction in a human liposarcoma...
[ 6 ] - Specific IgE to Common Food Allergens in Children with Atopic Dermatitis
Background: Atopic dermatitis is a major public health problem, often starting in early childhood and sometimes followed by other allergic diseases. Although hypersensitivity to foods is assumed to play an essential role in the development of atopic dermatitis in some patients, little is known about common food allergens in Iranian children with atopic dermatitis. Objectives: This study was des...
[ 7 ] - Association of HLA-DQA1*0101/2 and DQB1*0502 with Myasthenia Gravis in Southern Iranian Patients
Background: Myasthenia gravis is an autoimmune disorder of neuromuscular junction characterized by skeletal muscle weakness and fatigability. Different genes may control the induction and clinical presentation of this disease. Various HLA alleles are reported as predisposing or protective genetic elements in myasthenia gravis. Objective: The aim of this study was to investigate the probable as...
[ 8 ] - Analysis of Human Leukocyte Antigen class II Gene Polymorphism in Iranian Patients with Papillon-Lefevre Syndrome: a Family Study
Background: Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive disorder characterized by palmoplantar hyperkeratosis and early development of aggressive pe-riodontitis. Although cathepsin C (CTSC) gene mutations have been established in about 70-80% of PLS patients, it is assumed that the patients may have dysfunctioning of immune defense mechanisms. Objective: To assess the associat...
[ 9 ] - Antigen-Specific Antibody Response in Juvenile-Onset SLE Patients Following Routine Immunization with Tetanus Toxoid
Background: Infection is now the most common cause of morbidity in Systemic Lupus Erythematosus (SLE). There is lack of information regarding the specific antibody forma-tion in response to vaccines in young SLE patients. Objective: To determine the efficacy of anti-tetanus antibody response in young patients with SLE. Methods: Forty SLE pa-tients with mean age of 14.1 years (range: 7-21) and 6...
[ 10 ] - HLA Class I Gene Polymorphism in Iranian Patients with Papillon-Lefevre Syndrome
Background: Papillon-Lefevre Syndrome (PLS) is a rare autosomal recessive disorder characterized by diffused palmoplantar keratoderma and severe periodontitis. Increased susceptibility to infections due to impairment of the immune system is considered to be involved in pathoetiology of this disease. Objective: According to the crucial function of HLA molecules in immune responses and associati...
[ 11 ] - HLA class II Genetic Diversity in Arabs and Jews of Iran
Background: Anthropological studies based on highly polymorphic HLA genes pro-vide useful information for bone marrow donor registry, forensic medicine, disease as-sociation studies, as well as designing peptide vaccines against tumors, and infectious or autoimmune diseases. Objective: This study was designed to investigate the genetic relationship of Iranian Arabs and Jews using HLA-class II g...
[ 12 ] - Iranian Lurs Genetic Diversity: An Anthropological View Based on HLA Class II Profiles
Background: HLA genes are highly polymorphic and certain alleles are frequent only in specific populations. Therefore, HLA is a unique tool for studying the genetic relationship between different populations. Iranians are ethnically diverse people and one of the major ethnic groups in Iran is Lur population inhabiting along the central and southern parts of Zagros Chain Mountain. Objectives: Ge...
[ 13 ] - Physicochemical and Immunomodulatory Properties of Gum Exudates Obtained from Astragalus myriacanthus and Some of Its Isolated Carbohydrate Biopolymers
Plants gums are complex mixtures of different polysaccharides with a variety of biological activities and pharmaceutical applications. Few studies have focused on physicochemical and biological properties of gums obtained from different plants. This study was designed to determine potential pharmaceutical and pharmacological values of the gum exudates and its isolated biopolymers obtained from ...
[ 14 ] - Inhibition of NR2B-Containing N-methyl-D-Aspartate Receptors (NMDARs) in Experimental Autoimmune Encephalomyelitis, a Model of Multiple Sclerosis
Neurodegeneration is the pathophysiological basis for permanent neurological disabilities in multiple sclerosis (MS); thus neuroprotection is emerging as a therapeutic approach in MS research. Modulation of excitotoxicity by inhibition of NMDARs has been suggested for neuroprotection, but selective antagonisation of the NR2B subtype of these receptors, a subtype believed to play a more pivotal ...
