title: Interleukin-10: biology, role in inflammation and autoimmunity.
abstract: OBJECTIVE
  Reading this article will increase the readers' knowledge of the biology of interleukin-10 (IL-10) an important cytokine. The survival of an organism and its host defense mechanisms require, among other processes, a complex but target-oriented interaction and an interdependence between the immune and inflammatory pathways. The biologic role of interleukin-10 in these processes is presented as well as the possible involvement of IL-10 in the pathogenesis of various diseases. The influence of pharmacologic agents on IL-10 production and the possible pharmacologic role of IL-10 itself are discussed.
  
  
  METHODS
  A detailed literature search was conducted. Studies considered relevant and important involving both humans and animals, in all languages were used.
  
  
  METHODS
  Material was taken only from peer reviewed journals.
  
  
  RESULTS
  IL-10 is produced by CD4+, Tho, Th1, B lymphocytes, mast cells, eosinophils, monocytes, macrophages and keratinocytes. IL-10 has a diverse array of actions, which differ depending on cell type, nature of stimulus and the cellular microenvironment. Interleukin-10 has an important role in the inflammatory and immune systems. In addition, present studies suggest that IL-10 may well play a pivotal role in the pathogenesis of several diseases. It has the potential for therapeutic use. Most of the data on IL-10 have been obtained from in vitro studies or animal experiments. Studies on humans are few, but rapidly increasing.
  
  
  CONCLUSIONS
  Interleukin-10 is an important molecule with a central role in maintaining health and in the pathogenesis of disease. Known pharmacologic agents and some under investigation can modify IL-10 production in vivo. Development of agents that can selectively affect a very specific biologic action of IL-10 may provide significant benefit in treating autoimmune and inflammatory diseases.
