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 ...

objective(s): systemic candidiasis is an infection of candida albicans (c. albicans) causing disseminated disease and sepsis, invariably when host defenses are compromised. we investigated the histopathological changes as well as the lymphoproliferative responses and cytokine production of splenic cells after stimulation with concanavalin a (con a) and pokeweed mitogen (pwm) in mice with dissem...

NKT cell subsets can be divided based on CD4 and NK1.1 expression and tissue of origin, but the developmental and functional relationships between the different subsets still are poorly understood. A comprehensive study of 19 cytokines across different NKT cell subsets revealed that no two NKT subpopulations exhibited the same cytokine profile, and, remarkably, the amounts of each cytokine prod...

stage-specifci developmental forms of lesihmania major promastigotes were grown in vitro. procyclic and metacyclic promastigotes were cultured and separated by peanut agglutinin. the axenic amastigote form were prepared by culturing the promastigotes in acidic medium at 35c.these three forms of parasites were used as antigens to study cytokine production in whole blood culture of healthy indivi...

the introduction of ex vivo lung perfusion (evlp) in the practice of lung transplantation has allowed the reconditioning of the marginal grafts and their conversion into transplantable grafts. in addition, evlp can provide a platform for the application of various preventive measures to decrease the incidence of post-transplant complications. while the toronto team targets the attenuation of th...

Interleukin (IL)-17 is exclusively produced by CD4 helper T-cells upon activation. It most often acts as a pro-inflammatory cytokine, which stimulates the release of pro-inflammatory cytokines IL-6, IL-8, TNF-α, and granulocyte-macrophage colony-stimulating factor (GM-CSF). In this study, we studied the in-vitro IL-17 response to specific antigens and a variety of mitogens and compared the IL-1...

conclusions in this study, the l-lps immune response of bovine cells was significant, indicating that tlr2 is the predominant receptor for l-lps. due to l-lps endotoxin-like activity, we found a strategy through using bmap-28 to prevent l-lps-induced tlr2-dependent immune activation in bovine cells. materials and methods in this study, l-lps-induced proinflammatory cytokine production in bovine...
