atopic dermatitis (ad) is a common chronically relapsing skin disease associated with abnormal cytokine production, and activation of t-helper 2 cells. the aim if this study was to determine whether cytokine gene polymorphisms might influence the development of ad. single nucleotide polymorphisms in the genes for i-l1alpha, il-1beta, il-1r, il-2, il-4, il-6, il-10, il-12, tgf beta, tnf and ifng...
different research groups have extensively studied the associations of cytokine gene polymorphisms in different diseases. the role of cytokines gene polymorphisms in multiple sclerosis (ms), as a chronic immune-mediated neurodegenerative disease, has been previously reported in the various populations. for determining pro-inflammatory cytokine gene polymorphisms, 100 relapsing remitting multipl...
background: β-thalassemia as a hereditary disease is defined as defective synthesis of β-globin chains, resulting in erythropoiesis abnormalities and severe anemia. different studies have shown that cytokines and cytokine gene polymorphisms play a major role in the pathogenesis of β-thalassemia. single nucleotide polymorphisms (snps) within the promoter region or other regulatory sequences ...

Different studies have shown that cytokines and cytokine gene polymorphisms play a major role in the pathogenesis of β-thalassemia. Single nucleotide polymorphisms (SNPs) within the promoter region or other regulatory sequences ...
background: in addition to human leukocyte antigens (hla) compatibility, gene polymorphisms in cytokines might also be important in the quality of allogeneic immune response. objective: to evaluate the influence of hla-dr matching and a number of cytokine gene polymorphisms on acute rejection after living-unrelated donor (lurd) kidney transplantation. methods: a total of 42 renal transplants pe...
Background: Helicobacter pylori (H. pylori)is agramnegative bacterium thatcolonizes stomach mucosa andcausesupper gastrointestinal diseases.Interleukin-13 is a preventive immune cytokine produced by many immune cells. IL-13 gene is located on chromosome 5 q 25 bp. It has polymorphisms at positions -1512 A/ C and +2044 G/A, which are associated with the expression rate of this cytokine .The aim ...
bronchial asthma is a multifactorial disease whereby both environmental and genetic factors contribute to its aetiology and/or clinical severity. the aim of this study was to examine the association of 22 cytokine gene polymorphism in the macedonian population with bronchial asthma (ba). the sample of the population comprised of 301 normal unrelated individuals and 74 patients with ba. cytokine...
Background: In addition to Human Leukocyte Antigens (HLA) compatibility, gene polymorphisms in cytokines might also be important in the quality of allogeneic immune response. Objective: To evaluate the influence of HLA-DR matching and a number of cytokine gene polymorphisms on acute rejection after living-unrelated donor (LURD) kidney transplantation. Methods: A total of 42 renal transplants pe...
Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...
Abstract: Background and Aim: The increasing incidence of infertility is alarming. About 10-30% of infertility are classified as Unexplained Infertility (UI) which is not an absolute clinical condition. TGF-b1 is multifunctional cytokine and produced mainly by T regulatory (Treg) lymphocytes. This cytokine plays important roles in physiology of normal pregnancy. The association of Single...
