IL-1 alpha (Interleukin-1 alpha)

Product Description:

IL-1 alpha possesses a wide spectrum of metabolic, physiological, haematopoietic activities, and plays one of the central roles in the regulation of the immune responses. It binds to the interleukin-1 receptor. IL-1 alpha is constitutively produced by epithelial cells. It is found in substantial amounts in normal human epidermis and is distributed in a 1:1 ratio between living epidermal cells and stratum corneum. The constitutive production of large amounts of IL-1 alpha precursor by healthy epidermal keratinocytes interfere with the important role of IL-1 alpha in immune responses, assuming skin as a barrier, which prevents the entry of pathogenic microorganisms into the body. In vitro, IL-1 alpha possesses biological effect on cells in the picomolar to femtomolar range. In vivo, shortly after an onset of an infection into organism, IL-1 alpha activates a set of immune system response processes.
