This study investigated the association of tumor necrosis factor-α (TNF-α)-308, -238, and -863 polymorphisms with osteoarticular tuberculosis (OA-TB) prognosis in a Hebei population. Genomic DNA was extracted from venous blood samples of 120 OA-TB patients and 100 healthy volunteers. TNF-α-308, -238, and -863 were analyzed by PCR-restriction fragment length polymorphism; genotype and allele fre...

cytokines play a part in pathogenesis of periodontitis via inflammation phenomenon. aggressive periodontitis (agp) is a multifactorial disease resulting in rapid tooth loss due to severe destruction of tooth supporting apparatus. recently, researchers have focused on genetic susceptibility of periodontitis through investigating the gene variations of cytokines and other components of immune res...

BACKGROUND Two-thirds to three-fourths of patients with either refractory luminal or fistulizing Crohn disease respond to infliximab treatment. The ability or inability to respond seems to persist over time. Biological characteristics and/or genetic background can influence the response to treatment. The aim was to assess the value of C-reactive protein and TNF-alpha serum levels before treatme...

BACKGROUND The reasons for the viral persistence of hepatitis B virus infection (HBV) are unknown, but are probably related to host immune factors. Cytokines play a significant role in immune defense. The present study was undertaken to investigate the association between HBV infection and polymorphisms of tumor necrosis factor (TNF)-alpha and interleukin(IL)-10 gene promoter. METHODS A total...

Tumor necrosis factor (TNF) production and non-Hodgkin lymphoma (NHL) outcome was found to be related to the TNF(-308) polymorphism. To explore whether this could be linked to neighboring polymorphisms, we genotyped the TNF(-376,-308,-238,-163), lymphotoxin alpha (LTalpha)(+252), and HLA DRB1 alleles in 204 patients with NHL and 120 controls. TNF(-308A) was the only allele associated with highe...

BACKGROUND AND AIMS Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease of unknown aetiology. Abnormalities in immune regulation and genetic associations suggest that PSC is an immune mediated disease. Several polymorphisms within the tumour necrosis factor alpha (TNF-alpha) and interleukin 10 (IL-10) promoter genes have been described which influence expression of these...

We studied 88 multibacillary (MB) leprosy patients, who received multidrug therapy (MDT) treatment in hyperendemic (44 persons) and hypoendemic (44 persons) areas in Gowa Regency, South Sulawesi, Indonesia. Bacteriological examinations were carried out (bacteria index and morphology index), immunological examinations (MLPA and TNF-alpha) and genetic variation in blood and ear lobe slit skin sme...

Asthma is a chronic inflammatory and remodeling disorder of the airways, in which many cells, cellular elements, and cytokines play important roles. The role of tumor necrosis factor-α (TNF-α) in asthma is unclear in Pakistani population. The aim of this study was to assess the relationship between TNF-α-308 polymorphism and asthma. Polymorphism of TNF-α (G-308-A locus; rs 1800629) in 329 asthm...

OBJECTIVE Proinflammatory cytokines contribute to systemic low-grade inflammation and insulin resistance. Tumor necrosis factor (TNF)-alpha impedes insulin signaling in insulin target tissues. We determined the role of inhibitor of nuclear factor-kappaB kinase (IKK)beta in TNF-alpha-induced impairments in insulin signaling and glucose metabolism in skeletal muscle. RESEARCH DESIGN AND METHODS...

BACKGROUND Pro-inflammatory cytokine gene polymorphisms are potential candidates for susceptibility for both type 2 diabetes mellitus (DM) and chronic periodontitis (CHP). This study explored the association of interleukin-1 beta (IL-1 β) +3954, interleukin-6 (IL-6) -597/-174 and tumor necrosis factor-alpha (TNF-α) -308 single nucleotide polymorphisms in CHP with and without type 2 DM in Malaya...
