Introduction Cytokines are a group of regulatory proteins critically involved in many physiological processes such as immune recognition, cell differentiation and cell proliferation. They have been identified in many vertebrate species and are produced by a variety of different cell types. Cytokines are usually produced transiently and locally, acting in a paracrine or autocrine manner. They interact with high affinity cell surface receptors specific for each cytokine or cytokine group and are active at very low concentrations mostly in the picogram range. It is well known now that the type of an antigen-specific immune response largely depends on the selection or preferential activation of defined CD4+ T-cell subsets (i.e. Th1 and Th2). Activation of these subsets is characterized by the secretion of distinct patterns of cytokines. Th1, but not Th2 cells, primarily secrete IL2 and IFN-gamma while Th2, but not Th1 cells, produce IL4, IL5, IL6, IL10 and IL13. Other cytokines, such as TNF-alpha and GM-CSF are produced by both Th subsets. In addition, the production of IL12 and IL10, produced by antigen presenting cells, (APC) such as macrophages and dendritic cells, critically contributes to the preferential expansion of Th1- or Th2 -type cells. For instance, early production of IL12 is considered essential for the development of Th1 cells. On the other hand, the absence or low concentrations of IL12 and IFN-gamma in the early phase of an immune response and concomitant production of IL4 by cells of the mast cell/basophil lineage or T-cells themselves is known to favor the development of Th2 cells. In addition to their regulatory effects on Th subset differentiation, the cytokines released by the two types of Th cells also produce distinct effector functions. For instance, IL4 and IFN-gamma have differential or antagonistic activities on immunoglobulin isotype selection or Major Histocompatibility Complex (MHC) class II expression. Therefore, the properties of an immune response can be best studied by determining the amounts of cytokines produced by the responding T-cells and APC.
