Buruli ulcer (BU), caused by infection with Mycobacterium ulcerans, is a chronic necrotizing human skin disease associated with the production of the cytotoxic macrolide exotoxin mycolactone. Despite extensive research, the type of immune responses elicited against this pathogen and the effector functions conferring protection against BU are not yet fully understood. While histopathological ana...

Interleukin-13 and interferon-γ are important effectors of T-helper cells. Interleukin-13 increases expression of the arachidonic acid-metabolizing enzyme, 15-lipoxygenase-1, in a variety of cell types. 15-lipoxygenase-1 is dramatically elevated in the airways of subjects with asthma. Studies in animals indicate that 15-lipoxygenase-1 contributes to the development of allergic airway inflammati...

We report a case of disseminated Mycobacterium genavense infection resulting from neutralizing anti-interferon-γ autoantibodies in the patient. We identified M. genavense targeting the hsp65 gene in an aspiration specimen of the lymph node. Adult-onset immunodeficiency caused by neutralizing anti-interferon-γ autoantibodies, in addition to HIV infection, can lead to disseminated nontuberculous ...

interferon gamma (ifn-γ) is one of the key cytokines in defining t helper 1 lymphocyte immuneresponses. in this study, the bovine ifn-γ gene was cloned from spleen tissue rna using the reversetranscription-polymerase chain reaction (rt-pcr). ifn-γ cdna was sub-cloned and expressed inmammalian expression plasmid (pcdna3.1(+)) under the control of the human cytomegalovirus (cmv)promoter. the pred...

It is now well documented that interferon gamma (IFN-γ) is the indispensable cytokine for inducing protective immunity against experimental and human cutaneous leishmaniaisis. The importance of IFN-γ receptor (IFN-γR) has also been studied. In the present study, we made attempts to find out whether L. major infection is able to alter the expression of IFN-γR in vivo. In addition, we studied the...

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...

BACKGROUND In vitro and animal studies have demonstrated that Chlorella is a potent biological response modifier on immunity. However, there were no direct evidences for the effect of Chlorella supplementation on immune/inflammation response in healthy humans. METHODS This study was designed for an 8-week randomized, double-blinded, placebo-controlled trial: 5g of Chlorella (n=23) or Placebo ...

background: cesarean section delivery can lead to much maternal morbidity. different cytokines have been reported to be influenced by the mode of delivery. objective: to investigate the influence of mode of delivery on maternal, placental and cord sera of interferon gamma (ifn-γ), interleukin-4 (il-4) and interleukin-10 (il-10) levels. methods: these three cytokines were measured using elisa in...

Invasive fungal infections remain among the most frequent severe and fatal complications of oncology, despite effective antifungal agents. Genetic aberrations may additionally increase individual patient’s susceptibility to invasive mycosis, with need for an intensified treatment, such as adjunctive immunotherapy combined standard medication. Interferon-gamma (IFN-γ) immunostimulatory agent rep...

background: the aim of this study was to determine the th1 and th2 serum cytokines, in patients with psoriasis and to com pare their cytokine levels with those of normal control subjects. methods: serum levels of interferon-gamma (ifn-γ), interleukin-2 (il-2), interleukin-4 (il-4), and interleukin-10 (il-10) were measured by enzyme linked immunosorbent assay in 40 patients with psoriasis and in...
