Interleukins are proinflammatory cytokines produced on cell injury or trauma. There are two closely related types of interleukins produced by the cell, IL-1α and IL-1β that are produced by the activation of NF-κ B transcription factor in response to bacterial infection or LPS. Both IL-1α and IL-1β exert their cellular effects by signalling through IL-1 receptor type 1. A variety of cells such as macrophages, epithelial cells, fibroblasts, keratinocytes, monocytes and dendritic cells secrete IL-1α. Both IL-1α and IL-1β are important in acquired immunity, inflammation, response to infection and production of matrix metalloproteinases (MMPs). The effects of IL-1α are mediated by activation of NF-κB, JNK and MAPK pathways that activated the genes in response to infection and inflammation. Overproduction of IL-1α has been implicated in inflammatory disorders like rheumatoid arthritis and periodontitis Anti-interleukin-1α specifically reacts with human IL-1α. It does not react with human IL-1β and mouse IL-1β or mouse IL-1α.
Immunogen
purified, E. coli-derived recombinant human interleukin-1α.
Application
Anti-interleukin 1α antibody may be used for immunoblotting at a working concentration of 0.1-0.2 μg/ml. For immunohistochemistry the recommended concentration is 0.5-5 μg/ml. The antibody is suitable for neutralization reactions.
Physical form
Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline with 5% trehalose.

IL-1 strikingly enhances antigen-driven responses of CD4 and CD8 T cells. It is substantially more effective than LPS and when added to a priming regime of antigen plus LPS, it strikingly enhances cell expansion. The effect is mediated by direct

All biological agents currently used for reducing TNFalpha activity in disease are neutralization strategies; however, there are several strategies for reducing interleukin (IL)-1 activities: the IL-1 receptor antagonist (IL-1Ra), anti-IL-1beta monoclonal antibodies, the IL-1 Trap, IL-1 receptor type I antibodies

Understanding cytokine immunobiology is central to the development of rational therapies for destructive inflammatory diseases such as rheumatoid arthritis (RA) and periodontitis. The classical interleukin-1 (IL-1) family cytokines, IL-1alpha and IL-1beta, as well as IL-18, play key roles in inflammation.
