چکیده

The objective of our work was to evaluate the effect of interferon-γ (IFN-γ) on cytokine expression in rat acute pancreatitis (AP). AP was introduced to rats which were divided into Control, AP and IFN-γ group. Rats in the AP and IFN-γ group were sacrificed as 6, 12 and 24 h after IFN-γ treatment. The serum amylase (AMA), endotoxin and cytokines were detected. The pathological examination and immunofluorescence staining of pancreas for TNF-α, NF-κB and IL-18 were performed. The serum AMA increased significantly at 6 h and reduced at 48 h after AP. The increase in IFN-γ was higher than that in AMA. IL-18 increased in the AP and IFN group, and IFN increased markedly at 48 h after AP. IL-27 reduced at 24 h after AP compared with AP group. In the AP group, the immunostaining of cytokines increased. In the IFN group, the edema in the pancreas was more severe, and NF-κB and IL-18 expression was higher than that in the other two groups. IFN-γ can increase serum IL-18 and reduce IL-27 in AP. IFN-γ can increase serum IL-18 and reduce serum IL-27 in AP. The increase in NF-κB and IL-18 may exert influence on pro-inflammatory cytokines to deteriorate inflammation in the pancreas. Thus, to control the IFN-γ might has promise to attenuate pancreatitis.

Immunopotentiotor Effect of α-Tocopherol on Cytokine Expression in the Lymphocytes in the Elderly People

Background: Aging is associated with attenuation of immune responses. Studies show that old people are vulnerable to infectious diseases such as influenza. α-Tocopherol as an immunomodulator affects immune responses. In the present study, the effect of α-tocopherol, on lymphocyte responses i.e. interferon-gamma (IFN-γ), Tumor Necrosis Factor-alpha (TNF-α), and nuclear factor-κB (NF-κB)  in elde...

The Effect of Beta Interferon on Dendritic Cells and Cytokine Synthesis by CD4+ T Cells

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...
