Research Abstract |
We isolated a novel gene ZFAT, which contains Zn finger and AT-hook domains by genome wide linkage analysis of AITD. We found that ZFAT negatively regulates a group of genes related to cytokine production and components of antigen receptor complexes. ZFAT was shown to be important in early development, because ZFAT knockout mice were embryonic lethal. ZFAT +/- heterozygous mice showed increased lymphocytes, augmented BCR responses and delayed GvHD reactions, suggesting that ZFAT is related to B cell growth and regulation of Th1/2 balance.
