BACKGROUND The immune system plays a pivotal role in myocardial homeostasis and response to injury. Interleukins-4 and -13 are anti-inflammatory type-2 cytokines, signaling via the common interleukin-13 receptor α1 chain and the type-2 interleukin-4 receptor. The role of interleukin-13 receptor α1 in the heart is unknown. METHODS AND RESULTS We analyzed myocardial samples from human donors (n...
background t-helper (th) lymphocyte cytokine production may be important in the immune pathogenesis of hepatitis c virus (hcv) infections. th1 cytokines such as; interleukin- 2 (il-2), and interferon gamma (ifn-gamma) are necessary for host antiviral immune responses, while th2 cytokines (il-4, il-10) can inhibit the development of these effector mechanisms. objectives the aim of the present st...
objective(s):development of new generation of vaccines against leishmaniasis is possible because long-term protection is usually seen after recovery from cutaneous leishmaniasis. iscomatrix is particulate antigen delivery system composed of antigen, cholesterol, phospholipid and saponin. in this study, the role of iscomatrix bilayer composition made by different phase transition temperature (tc...
objective(s): iscomatrix vaccines have now been shown to induce strong antigen-specific cellular or humoral immune responses to a broad range of antigens of viral, bacterial, parasite or tumor. in the present study, we investigated the role of iscomatrix charge in induction of a th1 type of immune response and protection against leishmania major infection in balb/c mice. materials and methods:...
Immune escape of tumor cells is one of the main obstacles hindering the effectiveness of cancer immunotherapy. We developed a novel strategy to block immune escape by transfecting tumor cells in vivo with genes of pathogenic antigens from Mycobacterium tuberculosis (TB). This induces presentation of the TB antigen on tumor cell surfaces, which can be recognized by antigen presenting cells (APCs...
A number of cytokines are active during the evolution of an inflammatory response, including tumor necrosis factor-alpha, interleukin-1, and novel chemotactic cytokines. This latter group of mediators belong to supergene families of inflammatory signals that play a key role in the selective recruitment of immune cells. In this presentation, we present data demonstrating, for the first time, end...

background: nutritional strategies targeting improvement of poultry performance and disease prevention are currently being developed and in this respect the dietary intake of spiced essential oils and pre-biotics in raising broilers is receiving attention. objectives: this study was conducted to compare the effects of diet containing ginger essential oils (geo) and mannan-oligosaccharide (mos) ...
