Background & Objective: Brucellosis is one of the most prevalent bacterial zoonotic diseases which afflicts both humans and animals. Genetic factors play an important role in susceptibility to brucellosis. One of these factors is interferon-gamma (IFN-g), which is vital in the defense mechanism against infectious diseases such as brucellosis. The purpose of this study was to ev...

Theiler's virus causes a persistent infection and a demyelinating disease of mice which is a model for multiple sclerosis. Susceptibility to viral persistence maps to several loci, including the interferon gamma locus. Inactivating the gene coding for the interferon gamma receptor makes 129/Sv mice susceptible to persistent infection and clinical disease, whereas inactivating the interferon gam...

The gamma interferon assay is used to identify Mycobacterium avium subsp. paratuberculosis-infected animals. It has been suggested that regulatory mechanisms could influence the sensitivity of the test when it is performed with cells from cattle and that the neutralization of interleukin-10 (IL-10) in vitro would increase the gamma interferon responses. To investigate the regulatory mechanisms ...

Anaferon, released-active from of antibodies to interferon-gamma, is an antiviral drug with immunomodulating activity. The long-term experience proved its efficacy and safety in the treatment and prophylaxis of a wide spectrum of viral and bacterial infections. The key mechanisms of anaferon action are the regulation of endogenous interferons, in particular interferon-gamma: induction conformat...

Substantial increases in the concentrations of the excitotoxin and N-methyl-D-aspartate-receptor agonist quinolinic acid (QUIN) occur in human patients and non-human primates with inflammatory diseases. Such increases were postulated to be secondary to induction of indoleamine 2,3-dioxygenase in inflammatory cells, particularly macrophages, by interferon-gamma. To test this hypothesis, human pe...

Celiac sprue is a T-cell-mediated enteropathy elicited in genetically susceptible individuals by dietary gluten proteins. To initiate and propagate inflammation, proteolytically resistant gluten peptides must be translocated across the small intestinal epithelium and presented to DQ2-restricted T cells, but the effectors enabling this translocation under normal and inflammatory conditions are n...

Background As COVID-19 immunomodulation has been a part of interest for studies, it found that severe coronavirus disease 2019 (COVID-19) is associated with hyper-inflammatory response and increased levels interleukin-6 (IL-6) interleukin-10 (IL-10). This can progress to cytokine storm syndrome eventually development acute respiratory distress (ARDS). Interleukin-1 receptor antagonist (IL-1RA) ...

tuberculosis is one of the most common infectious diseases in the world. in recent years, genetically approach has been developed. one of the interesting gene for investigator is ifn-γr1. in this study we determind susceptibility to tuberculosis with polymorphism of ifn-γr1 gene. fifthly patients with smear positive tuberculosis have been chosen randomly. they were matched with 54 healthy contr...
