BACKGROUND More than three billion populations are living under the threat of Japanese encephalitis in South East Asian (SEA) countries including India. The pathogenesis of this disease is not clearly understood and is probably attributed to genomic variations in viral strains as well as the host genetic makeup. The present study is to determine the role of polymorphism of TNF-alpha promoter re...

INTRODUCTION The etiopathogenesis of basal cell carcinoma (BCC) is multifactorial. The TNF-α gene seems to be an interesting gene candidate for BCC susceptibility because of the proinflammatory and immunosuppressive properties of its product. The aim of the study was to assess the frequency of -308 G/A and -238 G/A gene polymorphisms in the TNF-α gene and serum levels of cytokine in patients wi...

The mechanisms responsible for development of inflammatory bowel disease (IBD) have not been fully elucidated, although the main cause of disease pathology is attributed to up-regulated inflammatory processes. The aim of this study was to investigate frequencies of polymorphisms in genes encoding pro-inflammatory and anti-inflammatory markers in IBD patients and controls. We determined genotype...

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...

Tumor necrosis factor alpha (TNF alpha) is thought to be a critical mediator of malaria fever, and mild malaria was previously reported to be linked to the MHC region containing the tumor necrosis factor alpha gene (TNF). Thirty-four families from Burkina Faso were analyzed to test for linkage between polymorphisms within the MHC region and mild malaria using the maximum-likelihood-binomial (ML...

Although the etiology of Behçet's Disease (BD; MIM 109650) remains to be clearly elucidated, levels of tumor necrosis factor alpha (TNF-alpha) have been reported to be significantly elevated in BD patients, and TNF-alpha blockers have been demonstrated to exhibit some degree of therapeutic efficacy for a certain subset of BD sufferers. In this study, we have conducted an analysis of the TNFA ha...

Juvenile idiopathic arthritis (JIA) is the most frequent rheumatic disease in children and could lead to severe disability. The aim of this study was to determine the role of gene polymorphisms in predicting the clinical response of anti-TNF therapy in JIA patients. 68 patients with JIA and 20 healthy controls (HC) were included in the study, and patients with JIA received anti-TNF treatment fo...

Transient ischemic attack (TIA) is a brief cerebral ischemic incident. This study assesses the role of TNF-α and IL-6 single nucleotide polymorphisms (SNPs) as predictors of recurrent TIAs that have high risk of developing stroke. The current study enrolled 54 high risk (according to frequency of TIA) TIA (group1), 52 low risk TIA patients (group2) and 34 controls (group3). Polymerase chain rea...

The tumor necrosis factor alpha (TNF-α) is a cytokine that exerts neuroprotective and neurodegenerative effects. While some research suggests enhancing effects of the TNF-α gene (TNF-α -308G→A) on cognitive function, further research is needed to clarify the association between the TNF-α gene and specific areas of cognitive performance including their neurophysiological correlates. In this stud...
