PURPOSE To address the roles of the endogenously produced IL-1ra in the course of corneal neovascularization (CNV). METHODS CNV was induced by alkali injury and compared in wild-type (WT), IL-1 receptor antagonist (ra) knockout (KO) mice and anti-IL-1ra antibody-treated WT mice 2 weeks after injury. Angiogenic factor expression and leukocyte accumulation in the early phase after injury were q...
Interleukin (IL) 4 is a multifunctional T cell-derived cytokine that inhibits cytokine production and certain effector functions in human monocytes, while enhancing others. We show that IL-4 may contribute to the downregulation and resolution of an inflammatory response by selectively promoting expression of the IL-1 receptor antagonist (IL-1ra) that blocks the action of IL-1. IL-1ra specifical...
The objective of these studies was to characterize the IL-1 inhibitory activity present in normal and psoriatic epidermis from clinically stable lesions. Fractionation of normal epidermal cytosol on a molecular sizing column failed to reveal the presence of IL-1 inhibitory bioactivity. However, specific ELISAs indicated that both the IL-1 receptor antagonist (IL-1ra) and IL-1 alpha were present...
BACKGROUND There is growing evidence that intestinal epithelial cells (IECs) are involved in the mucosal immune system. AIM To assess the pattern of cytokines secreted by IECs and lamina propria mononuclear cells (LPMNCs). To achieve this, the expression and secretion of interleukin (IL)-1, IL-1 receptor antagonist (IL-1ra), IL-6, and IL-8 in human primary colonic and ileal IECs and LPMNCs fr...
Interleukin 1 Receptor antagonist (IL-1Ra) is highly elevated in obesity and is widely recognized as an anti-inflammatory cytokine. While the anti-inflammatory role of IL-1Ra in the pancreas is well established, the role of IL-1Ra in other insulin target tissues and the contribution of systemic IL-1Ra levels to the development of insulin resistance remains to be defined. Using antisense knock d...
Both IL-1α and IL-1β are highly inflammatory cytokines mediating a wide spectrum of diseases. A recombinant form of the naturally occurring IL-1R antagonist (IL-1Ra), which blocks IL-1R1, is broadly used to treat autoimmune and autoinflammatory diseases; however, blocking IL-1 increases the risk of infection. In this study, we describe the development of a novel form of recombinant IL-1Ra, term...
BACKGROUND Interleukin-1 receptor antagonist (IL-1Ra) is the primary therapy against autoinflammatory syndromes with robust efficacy in reducing systemic inflammation and associated organ injury. However, patients receiving IL-1Ra might be at increased risk of acquiring serious infections. AIMS To study whether IL-1Ra treatment deteriorates Staphylococcus aureus (S. aureus) septic arthritis a...
Background & Aims: Immune system abnormalities such as inflammation, increased autoimmunity and the skewed expression of soluble mediators, including cytokines have been observed in autistic patients. The present study aimed to compare the effects of vitamin D supplementation and/or aquatic exercise training on the serum level of inflammatory cytokines, including IL-1β and IL-1RA, and stereotyp...
Interleukin (IL) -1, a proinflammatory cytokine, increases in aneurysm, and the IL-1 receptor antagonist (IL-1Ra) modulates IL-1 activity endogenously. We show here that IL-1Ra-deficiency provokes spontaneous femoral artery aneurysm in mice lacking intervention such as surgery or drugs, providing easily attained observation at different ages as well as diminished mortality from operative proced...
OBJECTIVE To assess changes of interleukin 6 (IL-6) and interleukin 1 receptor antagonist (IL-1ra) in serum, sputum, and drained pleural fluid of patients operated on due to lung cancer. METHODS Twenty-seven patients treated with lobectomy or pneumonectomy, including 14 with complications and 13 without complications, were analyzed. Serum IL-6 and IL-1ra concentration was measured before, at ...
