Background: Lymphadenitis is the most common complication of BCG vaccination in children. Interferon-gamma (IFN-γ) plays a key role in immune response to Mycobacterial infections. In this study, the relationship of serum levels of IFN-γ and its receptor (CD119) to development of Bacillus Calmette Guerin (BCG) axillary lymphadenopathy was investigated. <em...

there are limited clinical investigations identifying the percentage of t helper 1 (th1) and t regulatory (treg) cells in stable as well as rejected kidney allografts, a concept which needs to be more studied. the aim of our study was to compare the percentage of cd4+ ifn-γ+ cells, the number of ifn-γ secreting cells and the amount of foxp3 expression in patients with or without stable graft fu...

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...

introduction: toxoplasma gondii is an obligatory interacelullar parasite that infects nucleated cells in its intermediate hosts. the aim of the present study was to determine the effect of vitamin d3 on the multiplication of t. gondii in peritoneal macrophage of balb/c mice and nitric oxide production by macrophages.  methods: according to usage of vitamin d3 (one dose or seven doses) and infγ ...

Alveolar macrophages (AMs) are not only important immune cell of the host, but also target a variety respiratory pathogens. They play an role in defense against pathogen invasion and maintaining tissue balance. Interferon (IFN)-γ is well known multipotent cytokine that has antiviral antibacterial activity enhances antigen presentation. To better reveal biological processes porcine AMs activated...

macular or maculopapular skin reactions are frequent events in skin allergies as well as in viral infections. clinically, the differentiation may be difficult in the absence of a clear relationship with drug intake or in the failure to detect measles virus-specific antibodies. studies on drug-specific t cell lines and t cell clones isolated from skin-allergy patients have suggested that these c...

Background: Dendritic cells (DC) are a key regulator of the immune response, and interferon- beta (IFN-β) is considered an immunomodulatory molecule for DC. Objective: The purpose of this study was to evaluate the ability of IFN-β treated DC to induce cytokine secretion by CD4+ T cells. Methods: Dendritic cells were generated from blood monocytes with granulocyte-monocyte colony-stimulating fac...

Objective: The interleukin-12/interferon-γ (IL-12/IFN-γ) pathway is the most validated cytokine regulating Mycobacterium tuberculosis infection. role of IL-12/IFN-γ axis in protecting against (TB) exhibited people having mutations genes encoding these cytokines. We aimed to study serum levels IL-12 and IFN-γ pediatric their correlation with clinical microbiological features. Material Methods: A...
