T cells are key players in immune-mediated rheumatoid arthritis (RA). We previously reported that interleukin (IL)-22+CD4+T helper (IL-22+ Th) cells and IL-22 critically control the pathogenesis of RA. Here we monitored circulating levels of different IL-22+ Th cell subsets and measured plasma levels of IL-22, IL-17, and interferon (IFN)-γ in 60 patients with active RA following 12-week combina...

In tegumentary leishmaniasis caused by Leishmania braziliensis, there is evidence that increased production of IFN-γ, TNF-α and absence of IL-10 is associated with strong inflammatory reaction and with tissue destruction and development of the lesions observed in cutaneous leishmaniasis (CL) and mucosal leishmaniasis (ML). We evaluate the role of regulatory cytokines and cytokine antagonists in...

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 i...

Several immune-related markers have been implicated in basal cell carcinoma (BCC) pathogenesis. The BCC inflammatory infiltrate is dominated by Th2 cytokines, suggesting a specific state of immunosuppression. In contrast, regressing BCC are characterized by a Th1 immune response with IFN-γ promoting a tumor suppressive activity. IL-23/Th17-related cytokines, as interleukin (IL)-17, IL-23 and IL...

interleukin (il)-35 is a newly discovered suppressive cytokine and has been shown to alleviate  inflammatory  and  autoimmune  diseases.  the  purpose  of  this  study  was  to investigate immunomodulatory capacity of il-35 in patients with allergic asthma.il-35 mrna expression levels in peripheral blood mononuclear cells (pbmcs) were detected  by  quantitative  real-time  pcr  (qpcr).  the  fr...

this study investigated the in vitro production of interferon-γ, interleukin (il)-10, il-12, and il-13, after antigenic stimulation of the cells (with leishmania antigen and lipopolysaccharide) using whole blood from patients with cutaneous leishmaniasis lesions caused by leishmania tropica and in volunteers with history of cutaneous leishmaniasis. elisa results showed that the mean production ...

conclusions moderate exercise for 8 weeks increased the ifn-γ and decreased the il-17 serum levels in the morphine-dependent rats. for this reason, this type of exercise can improve the function of the immune system during morphine withdrawal syndrome. results after 8 weeks of exercise, a significant increase was observed in the serum ifn-γ level in the ht group (251.17 ± 13.045) in comparison ...
