Abstract. Interleukin 1β has been proposed to play an essential role in the pathogenesis of IDDM by direct interaction with the pancreatic beta-cell. Glucocorticoids are widely used as immunosuppressive agents and have been suggested to interfere both with the production and action of interleukin 1. The aim of the present study was to evaluate the interaction between cortisol and interleukin-1 on the pancreatic beta-cell function in vitro. Newborn rat islets were precultured for seven days before they were exposed to interleukin 1 with or without addition of cortisol. The release of insulin to

Platelet-activating factor (PAF) is a potent lipid mediator, involved in thrombosis, inflammation, and atherosclerosis. The protective effect of wine and olive oil against atherosclerotic diseases is largely attributed to their phenolic compounds and mostly to resveratrol and tyrosol. Both compounds have been reported to inhibit PAF biosynthesis in interleukin-1β (IL-1β)-stimulated monocytes and also to attenuate PAF biosynthesis in cell lysates.

Abstract The murine Ly-6 locus controls multiple cell surface antigenic specificities with distinct cellular and tissue distributions. Although the functions of Ly-6 antigens are unknown, several of these antigens represent interesting markers of T cell differentiation and activation. In this work we used a panel of monoclonal antibodies (MAb) in conjunction with flow cytofluorometry (FCF) analysis to investigate the effect of interferon (IFN) on the surface representation of T cell-associated Ly-6 antigens. It was found that in vitro treatment of purified T cells from both C57Bl/6 (Ly-6.2) an

Abstract Background: Neuropsychological factors (NPF) (i.e., fatigue, pain, cognitive dysfunction, depression, stress, and sleep disturbance) are common in head and neck cancer (HNC) and often cluster together. They can impair a patient’s functional status and quality of life and are an obstacle to effective treatment and a full recovery. Metabolism and inflammation may be underlying mechanisms but may work differently across HPV-related and unrelated HNC. We explored the joint interaction of metabolism, inflammation, and NPF via a stratified multiomics network analysis of the pretreatment pla

Liver disorder often occurs in patients with inflammatory bowel disease (IBD); however, the changes in IBD-induced liver disorder at the intrinsic molecular level (chiefly metabolites) and therapeutic targets are still poorly characterized. First, a refined and translationally relevant model of DSS chronic colitis in C57BL/6 mice was established, and cecropin A and antibiotics were used as interventions. We found that the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 in the liver tissues of mice were highly increased in the context of DSS treatment but were lowered by

Human mast cells (hMCs) derived in vitro from cord blood mononuclear cells exhibit stem cell factor (SCF)-dependent comitogenic responses to T helper cell type 2 (Th2) cytokines. As cysteinyl leukotriene (cys-LT) biosynthesis is a characteristic of immunoglobulin (Ig)E-activated mucosal hMCs, we speculated that Th2 cytokines might regulate eicosanoid generation by hMCs. After passive sensitization for 5 d with IgE in the presence of SCF, anti-IgE–stimulated hMCs elaborated minimal cys-LT (0.1 ± 0.1 ng/106 hMCs) and abundant prostaglandin (PG)D2 (16.2 ± 10.3 ng/106 hMCs).

It has remarkable frontline clinical effects in this disease, however, the leukemic cells become resistant to IM in both chronic and blast phases. BCR/abl kinase can induce reactive oxygen species (ROS) and promote self-mutation which subsequently render IM to resistance and failure to eliminate all leukemia cells. This mechanism of resistance in IM (mutation) is caused by oxidant damage to DNA with kinase domain mutations, reduced IM binding and kinase inhibition. A
