Previous studies indicated that elevated serum levels of Interleukin -18 (IL-18) and human cytomegalovirus (HCMV) antibodies have a fundamental role in the pathogenesis Type I diabetic mellitus T1DM. Therefore, aim current study was to investigate possible overlap between Interleukin-18 with The (45) T1DM patients healthy controls were used detect IL-18 an ELISA Kit HCMV cobas c411 apparatus fo...

therosclerotic cardiovascular disease is one of the major causes of death in developed countries. Lipid accumulation, foam cell formation and inflammation are recognized as major features of atherosclerosis.1 Inflammatory cells, mainly macrophages and T cells, produce a wide range of inflammatory cytokines in atherosclerotic lesions, which contributes significantly to the progress of the diseas...

UNLABELLED Very little is known about the role of interleukin-1β (IL-1β) and interleukin-18 (IL-18) in urticaria. MATERIAL AND METHODS Serum levels of IL-1β, IL-1 receptor antagonist (IL-1RA), and IL-18 were measured in 56 children with urticaria and in 41 healthy subjects. RESULTS Serum IL-1β did not differ between children with acute urticaria and controls. Children with single episode of...

An excess of the proinflammatory substance IL-18 is present in joints of patients with rheumatoid arthritis (RA), and expression of IL-18 receptor (IL-18R) regulates IL-18 bioactivity in various cell types. We examined the expression of IL-18R alpha-chain and beta-chain and the biologic effects of IL-18 in fibroblast-like synoviocytes (FLS) after long-term culture. The presence of both IL-18R c...

Interleukin (IL)-18 induces interferon (IFN)-gamma synthesis and synergizes with IL-12 in T helper type 1 (Th1) but not Th2 cell development. We report here that IL-18 receptor (IL-18R) is selectively expressed on murine Th1 but not Th2 cells. IL-18R mRNA was expressed constitutively and consistently in long-term cultured clones, as well as on newly polarized Th1 but not Th2 cells. IL-18 sustai...

IL-18 is a product of macrophages and with IL-12 strikingly induces IFN-gamma production from T, B, and NK cells. Furthermore, IL-18 and 1L-12 synergize for IFN-gamma production from Th1 cells, although this combination fails to affect Th2 cells. In this study, we show that IL-12 and IL-18 promptly and synergistically induce T and B cells to develop into IFN-gamma-producing cells without engagi...

We show that interleukin-18 is constitutively produced by dendritic cells; synthesis and secretion are poorly affected by maturative stimuli. Challenge of dendritic cells with autologous anti-tetanus toxoid T lymphocytes results in a secretory switch, with induction of secretion of biologically active interleukin-18 and decrease of its intracellular content. Similarly, when dendritic cells are ...
