Background: Interferon gamma (IFN-γ), a cytokine produced by a variety of cells is involved in the immune response against M. tuberculosis. It activates the production of other cytokines and molecules that kill mycobacterium. IFN-γ also has diagnostic role in identification of active and latent tuberculosis. Objective: To determine the level of IFN-γ in the blood of TB patients. Methods: Ninety...

Background: Obesity is one of the most serious health problems associated with inflammation. It has been found that functional and resistance physical activities improve obesity and inflammation. The aim of this study was to investigate the effect High-intensity Functional training (HIFT) and Circuit resistance training (CRT) on serum levels of the pro-inflammatory factor interferon gamma (IFN-...

Interleukin-18 (IL-18) has recently been identified as an interferon- gamma-inducing factor and it plays an important role in the Th1 response. We measured serum levels of IL-18 and interferon-gamma (IFN-gamma) in 43 patients with pulmonary tuberculosis and 25 healthy control subjects. Significantly increased levels of circulating IL-18 and IFN-gamma were found in pulmonary tuberculosis as comp...

BACKGROUND Previously, we found minimal bacterial dissemination and no evidence of systemic inflammation in a rabbit sinusitis model in which the left maxillary sinus was inflamed by Bacteroides inoculation with the ostium closed. However, we observed an increase in anti-Bacteroides IgG antibodies in the contralateral sinus, lower airway, and middle ear, with an apparent increase in interferon ...

There are two theories that seek to explain the pathogenesis of cerebral malaria, the mechanical obstruction hypothesis and the immunopathology hypothesis. Evidence consistent with both ideas has accumulated from studies of the human disease and experimental models. Thus, some combination of these concepts seems necessary to explain the very complex pattern of changes seen in cerebral malaria. ...
