Background: Interferon-gamma [IFN-γ) is the most important cytokine in immune system. This protein has been expressed bacterial cells. However, cloning not an easy task. We aimed to clone, express, and purify recombinant mouse IFN-γ overcome problems favor of commercial purposes. Materials Methods: To amplify gene product for cloning, we primarily designed two specific primers target gene. Foll...

UNLABELLED While cervical cancer incidence and mortality rates have declined in the United States, this cancer represents a worldwide threat. Human papilloma viral infection causes cervical neoplasia (CIN). 3,3'-Diindolylmethane (DIM) prevents or inhibits the progression from cervical dysplasia to cancer. The aim of this study is to determine the most effective dose of DIM given continuously in...

Abstract Background To explore the differences of multiple cytokines secretion based on QuantiFERON-TB Gold Plus(QFT-Plus)antigens stimulation, and to screen with potential differentiate tuberculosis infection status. Methods Twenty patients diagnosed microbiologically active tuberculosis(ATB)in Peking Union Medical College Hospitaland Beijing Chest Hospital from February April 2022 were enroll...

To evaluate the effects of HIV on immune responses in cutaneous leishmaniasis (CL), we quantified cytokine levels from plasma and stimulated peripheral blood mononuclear cells (PBMCs) from individuals infected with HIV and/or CL. Gamma interferon (IFN-γ) and interleukin 13 (IL-13) levels and the ratio of IFN-γ to IL-10 produced in response to stimulation with soluble Leishmania antigens were si...

To investigate the effects of carvacrol supplementation diets in rainbow trout induced by LPS, we measured gene expressions relative to pro-inflammatory and apoptosis in kidney and liver. Fish, which that were studied by four different treatments with three replicates each, was 44.71±1.33 gr. All fish were infected with E. coli LPS (25 µg ml-1) expect control and only carvacrol containing diet ...

Mutations in the genes coding for cytokines, receptors, second messengers, and transcription factors of interferon gamma (IFN-γ) immunity cause Mendelian susceptibility to mycobacterial disease (MSMD). We report the case of a 7-year-old male patient with partial dominant (PD) IFN-γ receptor 1 deficiency who had suffered from multifocal osteomyelitis attributable to bacille Calmette-Guérin vacci...

the ds-rna activated protein kinase (pkr) is a serine-threonine kinase with mw of 68 kda. it belongs to a family of kinases that control one of the translational initiation factors, eif2. pkr is produced at high level in response to viral infection. this protein by phosphorylating eif2 inhibits cellular protein synthesis. in this study, the effect of gamma interferon (ifn-γ), an activator, and ...

Objective(s):In this study, the serum level of interferon-γ (IFN- γ) and interlukin-4 (IL-4) was evaluated as a marker of Th1 and Th2 immune response that influence the clinical course of cutaneous leishmaniasis[r1] . Materials and Methods: This cross-sectional study was conducted on 44 cases of cutaneous leishmaniasis (21 cases with healed lesions and 23 cases with chronic non-healing lesions...

  Toxoplasma gondii an intracellular parasite infected large proportion of the world population, but mostly without visible clinical signs in immunocompetent patients. The present study was performed to determined levels cytokines (IL-12 , IFN-γ) and human proflin-1 (PFN-1) sera 125 aborted women as case group 30 healthy (15 non pregnant 15 women) control groups Women's children Hospital A...
