BACKGROUND/AIM Decreased Natural killer cell activity (NKA) for interferon-gamma production (NKA-IFNγ) has been reported in cancer patients. The aim of this study was to determine the diagnostic performance of NKA-IFNγ for gastric cancer (GC). RESULTS NKA-IFNγ levels were decreased in 261 GC patients with all stages of tumor compared to those in 48 healthy donors (P < 0.001), and lower levels...
Melanoma treatment has been revolutionized by antibody-based immunotherapies. IFNγ secretion by CD8+ T cells is critical for therapy efficacy having anti-proliferative and pro-apoptotic effects on tumour cells. Our study demonstrates a genetic evolution of IFNγ resistance in different melanoma patient models. Chromosomal alterations and subsequent inactivating mutations in genes of the IFNγ sig...
background: although many experimental studies provide convincing evidence that type ii immunity is protective against helminths, recent data in mice demonstrate that th1 is also impor-tant in some cestodes like hymenolepis nana. objective: to identify the role of th1 and th2 lymphocytes in immunity against h. nana, the levels of il-12, ifnγ, il-5, and il-13 were de-termined in serum of humans ...
مقدمه: سرطان پستان به عنوان شایع ترین بیماری بدخیم در اغلب زنان دنیا، سالانه حدود 5/1 میلیون زن را مبتلا میکند و در ایران به عنوان اولین گروه سرطانهای بدخیم در زنان میباشد. با توجه به این که فعالیت ورزشی نقش موثری در تغییر فاکتورهای موثر در سرطان دارد اما تاثیر فعالیت بدنی بر سطوح عوامل موثر سرطان در انسانها یا حیوانات مبتلا به آن تا به حال مورد توجه جدی قرار نگرفته است. از این رو پژوهش حاض...
IFNγ (interferon γ ), a cytokine typically secreted by infiltrating immune cells in insulitis in Type 1 diabetes, is by itself not detrimental to β-cells, but, together with other cytokines, such as IL-1β (interleukin 1β) and TNFα (tumour necrosis factor α), or dsRNA (double-stranded RNA), it induces β-cell apoptosis. The complex gene and protein networks that are altered by the combination of ...
Natural killer (NK) cells have therapeutic potential for cancer due to their capacity for targeting tumor cells without prior sensitization. Our laboratory has developed an NK cell expansion protocol that generates large quantities of NK cells for therapeutic infusion that secret 20 times the amount of interferon gamma (IFNγ) than resting NK cells. IFNγ can upregulate major histocompatibility c...
HIV/CMV co-infected persons despite prolonged viral suppression often experience persistent immune activation, have an increased frequency of myeloid derived suppressor cells (MDSC) and are at increased risk for cardiovascular disease. We examined how HIV MDSC control CD4+ T cell IFNγ response to a CMVpp65 peptide pool (CMVpp65). We show that HIV/CMV co-infected persons with virologic suppressi...
Cytokines often display substantial toxicities at low concentrations, preventing their escalation for therapeutic treatment of cancer. Fusion proteins comprising cytokines and recombinant antibodies may improve the anticancer activity of proinflammatory cytokines. Murine IFNγ was appended in the diabody format at the C-terminus of the F8 antibody, generating the F8-IFNγ fusion protein. The F8 a...
Tumor-associated macrophages play an important role in tumor growth and progression. These macrophages are heterogeneous with diverse functions, eg, M1 macrophages inhibit tumor growth, whereas M2 macrophages promote tumor growth. In this study, we found that IFNγ and/or celecoxib (cyclooxygenase-2 inhibitor) treatment consistently inhibited tumor growth in a mouse lung cancer model. IFNγ alone...
The data presented here are related to the research article entitled "Age predicts cytokine kinetics and innate immune cell activation following intranasal delivery of IFNγ and GM-CSF in a mouse model of RSV infection" (Eichinger et al., 2017) [1]. The cited manuscript demonstrated that the macrophage-stimulating cytokine, interferon gamma (IFNγ), but not granulocyte macrophage-colony stimulati...
