The interferon response elicited by Salmonella typhimurium mutants in mice is not dependent on the presence of a complete cell wall lipopolysaccharide. In fact, a mutant (G30/C21) which has lost all the polysaccharide side chains and sugars of the O antigen and contains only 2-keto-3-deoxyoctonate and lipid is indistinguishable in its interferon-stimulating ability from the wild type which poss...

EKSTEEN, P. A . L. & HUISMAN S, H. Interferon induction by bluetongue virus and bluetongue virus ribonucleic acid. Onderstep oort]. vet . R es. 39(3), 125-132 (1972). The stimulation of interferon synthesis by bluetongue virus and by bluetongue virus ribonucleic acid was investigated in order to determine if there is a difference in the mechanism of induction. The molecular mass of the interfer...

INTRODUCTION Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease characterized by various clinical manifestations. Several cytokines interact and play pathological roles in SLE, although the etiopathology is still obscure. In the present study we investigated the network of immune response-related molecules expressed in the peripheral blood of SLE patients, and the effects o...

The biotechnology industry has established itself as a major source of new human therapeutic protein drugs which can be described as complex biological entities. The majority of these in production, such as erythropoeitin (EPO), interleukin-2 (IL-2), interferon (IFN), granulocyte colony stimulating factor (G-CSF), granulocyte macrophage-colony stimulating factor (GM-CSF) and tissue plasminogen ...

background molecular farming is the production of important recombinant proteins in transgenic organisms on an agricultural scale. interferons are proteins with antiviral and antitumor activities and can be used for viral infections and cancers treatments. objectives this study reports the transformation of inf α2b gene in tobacco plant for the first time in iran. materials and methods interfer...

immunological defense complex is involved: the role of complement, T-lymphocytes, NK-cells noted. Of particular importance among immune factors interferon-γ, which able to limit reproduction Candida fungi in early stages infection by stimulating response. This due fact that interferon-γ strongest stimulator effector functions macrophages (microbicidal activity, cytokine production), increases e...

Abstract Chronic alcohol consumption is associated with significant mortality and morbidity in people affected by Mycobacterium tuberculosis (Mtb) infection. Our Lab previously reported that diet increased young mice infected Mtb an Interferon-α (IFN-α) dependent manner. We also found CD11b+Ly6g+ cells are major source for IFN-α. In the current study, using single cell RNA sequencing, we furthe...

Mouse myeloid leukemic MI cells can be induced to differentiate into mature macrophages and granulocytes by differentiation-stimulating factor (D-factor) in conditioned medium of mouse peritoneal macrophages. Double-stranded RNA's, such as the copolymers of polyinosinic and polycytidylic acids and polyadenylic and polyuridylic acids, could not alone induce differentiation of the cells, but enha...

Interleukin-12 (IL-12) is a monocyte/macrophage-derived cytokine that is critical for T lymphocyte and natural killer cell activities and functions. In this study, we examined the regulation of IL-12 expression by human monocytes in response to bacterial lipopolysaccharide (LPS). Several novel aspects of IL-12 induction from monocytes were shown. Optimal expression of IL-12 mRNA and bioactivity...

The role of hormonal changes throughout the menstrual cycle on genital tract inflammation during chronic human immunodeficiency virus (HIV) infection is not well defined, but it has implications for HIV prevention. We assessed daily levels of 26 vaginal cytokines and chemokines from 15 women infected with HIV-1. Taking into account coexisting sexually transmitted infections, behavioral factors,...
