This study evaluated the effects of dietary anticoccidial drugs plus antibiotic growth promoters (AGPs) on parameters of immunity in commercial broiler chickens. Day-old chicks were raised on used litter from a farm with endemic gangrenous dermatitis to simulate natural pathogen exposure and provided with diets containing decoquinate (DECX) or monensin (COBN) as anticoccidials plus bacitracin m...
CpG island hyper-methylation (CIHM) is one of the major events in the gastric carcinogenesis and also occurs in non-neoplastic gastric mucosa. IL-17A, -17F and MIF have a crucial role in the gastric inflammation and carcinogenesis. The CIHM status in the non-cancerous gastric mucosa, in relation to IL-17A (-197G>A, rs2275913), -17F (7488T>C, rs763780) and MIF (-173G>C and -794 tetranucleotide r...
T lymphocytes that are involved in cellular mediated immunity include two types known as TCD8+ (Cytotoxic T lymphocytes) and TCD4+ (helper T lymphocytes). TCD4+ has four main subtypes, including TH1, TH2, TH17, and Treg Lymphocytes.TH17 lymphocytes play a role in defense against microbes that TH1 and TH2 lymphocytes have not the ability to respond to them. The most important cytokines, which ar...
The active vitamin D metabolite, 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3)), has been shown to be an important regulator of innate and adaptive immune function. In addition, synthesis of 1,25(OH)(2)D(3) from 25-hydroxyvitamin D(3) (25(OH)D(3)) by the enzyme 1α-hydroxylase in monocytes upon activation by TLR signaling has been found to regulate innate immune responses of monocytes in an intrac...
In a murine model of allergic asthma, we found that Tyk-2((-/-)) asthmatic mice have induced peribronchial collagen deposition, mucosal type mast cells in the lung, IRF4 and hyperproliferative lung Th2 CD4(+) effector T cells over-expressing IL-3, IL-4, IL-5, IL-10 and IL-13. We also observed increased Th9 cells expressing IL-9 and IL-10 as well as T helper cells expressing IL-6, IL-10 and IL-2...
سابقه و هدف: سرطان معده یکی از شایع ترین سرطان های دستگاه گوارشی در دنیا می باشد که در ایران نیز از شیوع بسیار بالایی برخوردار است. اینترلوکین -17 (il-17) یک سایتوکاین پیش التهابی می باشد است که توسط سلول های th-17 ترشح می شود و از طریق القای فاکتورهای مختلف باعث ایجاد و تقویت التهاب می شود. هدف از این مطالعه بررسی ارتباط پلی مورفیسم il-17 در بیماران مبتلا به سرطان معده و مقایسه آن با گروه شاهد...
Interleukin (IL)-23 is a heterodimeric cytokine composed of a unique p19 subunit, and a common p40 subunit shared with IL-12. IL-12 is important for the development of T helper (Th)1 cells that are essential for host defense and tumor suppression. In contrast, IL-23 does not promote the development of interferon-gamma-producing Th1 cells, but is one of the essential factors required for the exp...
IL-23 induces the differentiation of naive CD4(+) T cells into highly pathogenic helper T cells (Th17/Th(IL-17)) that produce IL-17, IL-17F, IL-6, and TNF-alpha, but not IFN-gamma and IL-4. Two studies in this issue of the JCI demonstrate that blocking IL-23 or its downstream factors IL-17 and IL-6, but not the IL-12/IFN-gamma pathways, can significantly suppress disease development in animal m...
Biologics that neutralize specific cytokines have improved outcomes for several immune-mediated disorders but may also increase risks for particular side effects. This article postulates potential immunologic consequences of inhibiting components of the IL-23/T-helper cell 17 pathway-the target of next-generation biologics for treating psoriasis-based on clinical phenotypes of inherent or acqui...
