background: interleukin (il)-23 and il-27 are two il-12-related cytokines which their function may dramatically influence the inflammatory response to tumor development. il-12 and il-27 seem to have antagonistic roles with il-23 in tumor site. in this study, il-23 and il-27 mrna expressions were analyzed in peripheral blood of patients with breast cancer and healthy volunteers using quantitativ...

Shiga toxins (Stxs) are bacterial virulence factors produced by Shigella dysenteriae serotype 1 and Escherichia coli strains. Stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. Additionally, Stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. The inflammatory cyto...

background: endometriosis is a frequent gynecologic disease with a severe impact on the quality of life in the affected women; its pathogenesis is yet to be fully understood, with an altered immunity as a possible key factor. the present study aimed to investigate the serum anti-inflammatory cytokine profile in the patients with endometriosis compared with the healthy controls. materials and me...

interleukin-1β (il-1β), the prototypical pro-inflammatory cytokine, is produced by macrophages following exposure to bacterial products. its role is to act upon several cell types at the site of infection to stimulate the production of pro-inflammatory molecules that will cause increase in vascular permeability. therefore, il-1β regulates the initiation and development of acute inflammation tha...

introduction: helicobacter pylori (h. pylori), is a bacterium responsible for upper gastrointestinal tract diseases. the 16s rrna is a common h. pylori gene which are usually preferred for diagnosis purpose. the aim of this study was to determine the prevalence and abundance of 16s rrna in fecal samples and also evaluate correlation between the level of 16s rrna and activities of the cytokines,...

background: multiple sclerosis (ms), a chronic inflammatory demyelinating disorder with neurodegenerative aspects, is more common among young adults, particularly women. methods: this molecular study was designed to investigate the il-7r α chain gene in iranian ms patients. we studied 60 ms patients, diagnosed based on 2005 r-mcdonald criteria and 60 apparently healthy individuals as the contro...

mendelian susceptibility to mycobacterial diseases (msmd) is a rare inheritance syndrome, characterized by a disseminated infection with mycobacterium in children following bcg vaccination at birth. regarding the vaccination program in iran, it may consider as a public health problem. the pathogenesis of msmd is dependent on either insufficient production of ifn-gamma (γ) or inadequate response...
