background: rheumatoid arthritis (ra) is a chronic multisystem autoimmune disease common in all races and ethnics. cytokines and cytokines receptors play an important role in ra pathogenesis and clinical presentation. objective: to investigate the serum levels of tnf-α, tnf-α ri, tnf-α rii and il-12 in ra patients and healthy control group. methods: in this study 43 patients fulfilling the revi...

introduction: immune system is involved in the etiology and pathophysiology of inflammation and vitamins are important sources of substances inducing nonspecific immunomodulatory effects. given the proinflammatory role of cytokines in the inflammation and pain induction, this study aimed to assess the effects of long-term administration of vitamin b1 on the proinflammatory cytokines, edema, and...

Background and Objective: Infection with the hepatitis C virus (HCV) is an endemic public health problem with long-term consequences, especially in Egypt. Egypt has one of the highest incidence rates of HCV worldwide. The current cross-sectional study aims to determine how prevalent occult HCV infection is and how it affects the individual's immune response. Methods: The studied adult patient...

UNLABELLED PREMISES AND OBJECTIVES: The evolution of the infection with the hepatic virus C depends on the defense of the organism, found under the control of a network of cytokines and chemokines. The mechanisms that are causing both viral persistence as well as hepatic pathology are not entirely elucidated. We have proposed to study the amount in which different categories of cytokines are in...

OBJECTIVES To analyse the serum levels of cytokines in leprosy patients, to correlate them with clinico-histopathological profile, and to study the effect of standard multidrug therapy on serum cytokine levels. DESIGN Serum immunoassays of TNF-alpha, IFN-gamma, IL-1 beta and IL-10 were performed by ELISA in 61 newly diagnosed cases of leprosy before starting therapy and during reactional epis...

Th1 lymphocytes produce cytokines such as IL-2, IFN-γ, and TNF-α, TNF-β and GM-CSF. IFN-γ is the most important Th1 cell cytokine that induces the production of IgG, activation of macrophages, enhancing phagocytosis, and also increasing MHC class I and class II molecules. Increasing serum level of Th1 cytokines have also been observed in MS patients. It has also been prov...

Some proand anti-inflammatory cytokines and angiogenesis-related factors play important roles in the inflammatory response after surgery. To study their kinetics and mutual relationships after major lung resection for lung cancer, concentrations of interleukin (IL)-6, -8 and -10 and vascular endothelial growth factor (VEGF) were measured in serum and pleural fluid. Venous blood and pleural flui...
