Role of the cyclosporin-sensitive transcription factor NFAT1 in the allergic response.
Proteins belonging to the NFAT (nuclear factor of activated T cells) family of transcription factors are expressed in most immune cell types, and play a central role in the transcription of cytokine genes, such as IL-2, IL-4, IL-5, IL-13, IFN-gamma, TNF-alpha, and GM-CSF. The activity NFAT proteins is regulated by the calcium/calmodulin-dependent phosphatase calcineurin, a target for inhibition by CsA and FK506. Recently, two different groups have described that mice lacking the NFAT1 transcription factor show an enhanced immune response, with tendency towards the development of a late Th2-like response. This review evaluates the possible role of NFAT proteins in the Th2 immune response and in the eosinophil-mediated allergic response.
