Induction of permeability across endothelial cell monolayers by tumor necrosis factor (TNF) occurs via a tissue factor–dependent mechanism: relationship between the procoagulant and permeability effects of TNF Tumor necrosis factor (TNF) has marked effects on permeability and procoagulant activity on tumor-associated neovascula-ture when used in isolation(More)
BACKGROUND Interleukin 1 (IL-1) is a pluripotent cytokine that promotes angiogenesis, tumor growth, and metastasis in experimental models; its presence in some human cancers is associated with aggressive tumor biology. The purpose of these studies was to characterize the role of IL-1 in human cancers and determine if inhibition of IL-1 via its receptor(More)
BACKGROUND Interleukin-2 (IL-2) has direct pluripotent effects on cells with immune and inflammatory function. Which of these effects has a critical role in mediating tumor regression remains enigmatic. In this study, we compared early changes in transcriptional profiles of circulating mononuclear cells with those occurring within the microenvironment of(More)
Interleukin (IL)-1 is a pleiotropic inflammatory cytokine that promotes angiogenesis and enhances tumor growth and metastases. We evaluated the effects of IL-1 receptor antagonist (IL-1ra) on tumor growth and metastases in human melanoma xenografts. We selected two human melanoma lines (SMEL and PMEL) with differential (high versus low, respectively)(More)
IL-1beta is a pleotropic cytokine that may mediate increased procoagulant activity and permeability in endothelial tissue during inflammatory conditions. The procoagulant effects of IL-1beta are mediated through induction of tissue factor (TF) but its alterations on vascular permeability are not well characterized. We found that IL-1beta induced a rapid and(More)
Background Immunotherapies have improved patient responses and survival , though not all patients benefit. Effective biomarkers may help to improve outcomes. Durvalumab is a human IgG1 mono-clonal antibody that inhibits PD-L1 binding to PD-1 and CD80, restoring antitumor immunity [1, 2]. PD-L1 expression on tumor or tumor-infiltrating immune cells measured(More)
