background and objectives: infection with human immunodeficiency virus (hiv) results in dysregulation of the cytokine profile. a switch from a t helper 1 (th1) to a th2 cytokine has been proposed as an important factor in progression of hiv infection to aids. the aim of the present study was to assess the level of th1 and th2 cytokines in hiv infected individuals in order to identify the switch...
coronary atherosclerotic disease is one of the most endangering health disorder worldwide. this study was designed to investigate the correlation between hla-drβ1 alleles and circulating th1/th2 type cytokines in coronary atherosclerosis. by elisa, th1/th2 type cytokines were determined in serum samples of 31 subjects with unstable angina, 27 subjects with chronic stable angina and 24...
background & aim: multiple sclerosis(ms) is the most common inflammatory disease of central nervous system which is caused by an autoimmune process leading to destruction of myelin sheath. in this disease, cd4+ t–lymphocytes, mostly of th1 phenotype, play important roles in destruction of neuronal tissues. because of the probable etiologic participation of ebv virus in immunopathogenesis of ms...
TNFα is an inflammatory cytokine and the caspase and apoptotic processes can be activated by TNFα There are two classes of TNFα (solTNF and tmTNFα) which are important from the receptor aspect, so that solTNFα and tmTNFα can attach to the TNFR1, but tmTNFα just attaches to the TNFR2. Microglia cells are resident immune cells of the central nervous ...
Introduction: Helicobacter pylori (H. pylori), is a bacterium responsible for upper gastrointestinal tract diseases. The 16s rRNA is a common H. pylori gene which are usually preferred for diagnosis purpose. The aim of this study was to determine the prevalence and abundance of 16s rRNA in fecal samples and also evaluate correlation between the level of 16s rRNA and activities of the cytokine...
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 ...
Background: Type I diabetes is an autoimmune disease characterized by T-cell Mediated destruction of pancreatic β-cells. A variety of environmental, genetic and Immunologic factors are involved in the development of the disease. IL18 is a cytokine secreted by macrophage and monocytes and play an important role in the pathogenesis of diabetes Type I through inducing IFN-γ production. It is shown...
Background and Objectives: Infection with human immunodeficiency virus (HIV) results in dysregulation of the cytokine profile. A switch from a T helper 1 (Th1) to a Th2 cytokine has been proposed as an important factor in progression of HIV infection to AIDS. The aim of the present study was to assess the level of Th1 and Th2 cytokines in HIV infected individuals in order to identify t...
Enhancement or inhibition of cytokine signaling and corresponding immune cells responses are critical factors in various disease treatments. Cytokine signaling may be inhibited by cytokine-neutralizing antibodies (CNAs), which prevents further activation of cytokine receptors. However, CNAs may result in enhanced-instead of inhibitory-cytokine signaling (an "agonistic effect") in various in vit...
