Interleukin 1

Interleukin-1. Interleukin-1 (IL-1) is the prototypic pro-inflammatory cytokine. There are two forms of IL-1, IL-1alpha and IL-1beta and in most studies, their biological activities are indistinguishable. IL-1 affects nearly every cell type, often in concert with another pro-inflammatory cytokine, tumor necrosis factor (TNF) Definition of interleukin-1. : an interleukin produced especially by monocytes and macrophages that regulates immune responses by activating lymphocytes and mediates other biological processes (such as the onset of fever) usually associated with infection and inflammation NCI Dictionary of Cancer Terms. Interleukin-1 is made mainly by one type of white blood cell, the macrophage, and helps another type of white blood cell, the lymphocyte, fight infections. It also helps leukocytes pass through blood vessel walls to sites of infection and causes fever by affecting areas of the brain that control body temperature

Interleukin-1 is a hormone produced by cells in the blood stream that may be important in the process of rheumatic disease, due to its potential destructive effect on bone and joint structures Interleukin-1: A protein produced by various cells, including macrophages, interleukin-1 raises body temperature, spurs the production of interferon, and stimulates growth of disease-fighting cells, among other functions. Abbreviated IL-1. CONTINUE SCROLLING OR CLICK HERE FOR RELATED ARTICLE Interleukin 1. Interleukin-1 (IL-1) is a highly proinflammatory cytokine produced by multiple cell types, including epithelial cells, macrophages, dendritic cells, endothelial cells and B cells Interleukin 1. The receptors both exist in transmembrane (TM) and soluble forms: the soluble IL-1 receptor is thought to be post-translationally derived from cleavage of the extracellular portion of the membrane receptors Interleukin. The immunological functions of most of the interleukins are known to some degree. IL-1 and IL-2 are primarily responsible for activating T and B lymphocytes (white blood cells integral to bringing about the acquired immune response), with IL-2 being a stimulant of T- and B-cell growth and maturation

Abstract. IRAK-4 is an essential component of the signal transduction complex downstream of the IL-1- and Toll-like receptors. Although regarded as the first kinase in the signaling cascade, the role of IRAK-4 kinase activity versus its scaffold function is still controversial IL-1 is a proinflammatory mediator with 2 main ligands—IL-1α and IL-1β [39]—as well as a third naturally occurring competitive antagonist, IL-1Ra [40]. Stroke causes upregulation of the IL-1 receptor and its ligands in animal models [41], with expression of IL-1α seen in microglia within 4 h postreperfusion [42] The interleukin-1 receptor I (IL-1RI) is critical for host resistance to Mycobacterium tuberculosis (Mtb), yet the mechanisms of IL-1RI-mediated pathogen control remain unclear Other names: Interleukin-2. Proleukin® is the trade name for the generic drug name Aldesleukin. IL-2 and Interleukin-2 are other names for Aldesleukin. In some cases, health care professionals may use the trade name Proleukin® or other names IL-2 and Interleukin-2 when referring to the generic drug name Aldesleukin
