background and aims: several studies have shown that there is greater number of viruses in deep periodontal pockets than in normal gingival sulcus. we also know that virus may have an important role in induction of il-1β secretion by different human cells. in this study we intended to determine the capacity of herpes simplex virus type 1 to stimulate il-1β secretion in human gingival keratinocy...

objective: stevioside is a natural non-caloric sweetener which has been reported to have anti-inflammatory activity.  the aim of  the present study was to examine in vitro and in vivo effects of  stevioside on rats  plasma levels of tumor necrosis factor- α (tnf-α),  interleukin-1β (il-1β), tnf-α and il-1β release from lipopolysaccharide(lps)-stimulated rat peripheral blood mononuclear cells (p...

objective(s): study of non-coding rnas is considerable to elucidate principal biological questions or design new therapeutic strategies. mirnas are a group of non-coding rnas that their functions in pi3k/akt signaling and apoptosis pathways after t cell activation is not entirely clear. herein, mirnas expression and their putative targets in the mentioned pathways were studied in the activated ...

background & objective: interleukin (il)-10 is an important anti-inflammatory and immunomodulatory cytokine. some authors believe that single nucleotide polymorphisms (snp) in the promoter region of the il-10 gene have been associated with susceptibility to hiv infection and progression to aids, but its role is not clearly defined yet. the present study was undertaken to evaluate the associ...

rna extraction is a prerequisite technique for gene expression studies, analyzing the etiology and disease progression, treatment effects, as well as designing the diagnostic methods. although many rna extraction kits have been commercialized, but these kits are expensive and are not accessible in some countries. many studies have shown that trizol is an applicable material for the rna extracti...

present investigation was carried out to identify dna polymorphism of il-2rγ and chb6 genes. sixty five birds belonging to the indigenous chicken of himachal pradesh were utilized. good quality dna samples were subjected to pcr-rflp analysis using chicken specific primers. overnight restriction enzyme digestion was carried out at 37°c with iu hph i and pvu ii for il-2rγ and chb6 genes, respecti...

background: crohn’s disease (cd) and ulcerative colitis (uc) are two major clinical presentations of inflammatory bowel disease (ibd). many novel candidate genes have been found to be associated with increased risk for ibd. recently il-23 receptor gene is identified as an ibd associated gene in genome-wide studies. objective: to ascertain whether rs7517847 and rs1004819 snps in the il-23 recept...
