Tumour necrosis factor (TNF)alpha is a cytokine endowed with potent inflammatory properties that may contribute to airway inflammation in asthma. It has previously been shown that the single base pair polymorphism-308 (G to A substitution) in the promoter of TNFalpha gene results in enhanced cytokine secretion. Whether this polymorphism is associated with the presence of phenotypic expression o...

BACKGROUND In coronary in-stent restenosis (ISR), a substantial contribution of inflammation is assumed. We evaluated the association between polymorphisms in the Toll-like receptor 4 (TLR4) gene and cytokine response after lipopolysaccharide (LPS) challenge and the development of ISR. METHODS Patients were included after successful elective stent placement in a native coronary artery and wer...

In this report, β-tubulin gene polymorphism was investigated in Haemonchus contortus  populations isolated from sheep flocks in different regions of Khouzestan province, southwestern Iran. The samples were chosen on the basis of regional variation in benzimidazole treatment background of sheep flocks. Our objective was to study the relationship between treatment background andβ -tubulin gene po...

The growth hormone receptor (GHR) is a member of cytokine/hematopoietin family that mediates the biological actions of growth hormone (GH) on target tissues. Therefore, the purpose of this study was to examine the association of TG-repeat polymorphisms in the 5’-flanking region of bovine GHR gene with milk production traits and somatic cell score (SCS) in Holstein cattle of Iran. The part of 5’...

Background: Multiple sclerosis (MS), as a multifactorial autoimmune disease with complex genetic basis, causes demyelination in the central nervous system via cytokine responses to myelin antigens. Myelin basic protein (MBP) is the main protein component of the myelin sheath. HLA-DRB (human leukocyte antigen-DR beta) alleles, particularly HLA-DRB1*1501, may be of significance in the pathogenesi...

Background: chronic rhinosinusitis with nasal polyps (CRSwNP) is a multifactorial disease, those mechanisms are not fully understood. A significant role of cytokines, e.g., interleukin (IL)-1β, tumor necrosis factor (TNF) α, IL-10, IL-17А, IL-4, and their genes, in the pathogenesis predisposition to CRSwNP treatment efficacy established. Aim: investigate IL-1β (Т-31С), TNF-α (G-308A), IL-10 (G-...

Certain cytokine gene polymorphisms have been shown to correlate with outcome of human leukocyte antigen (HLA) identical sibling donor stem cell transplantation (SCT), but in unrelated donor SCT such information is scarce. We have studied the association between cytokine gene polymorphism and transplant-related mortality (TRM) in 182 unrelated SCTs performed at a single center. We found associa...
