Key Event Description
Naïve CD4 T cells can differentiate into several different types of T helpers, and Th2 cells, capable of producing IL-4, IL-5 and IL-13, are involved in humoral immunity against extracellular pathogens and in the induction of asthma and other allergic diseases. It was reported that GATA-3 promotes Th2 responses through three different mechanisms (Zhu J. 2006). Cell fate determination in each lineage requires at least two types of transcription factors: the master regulators (GATA3) as well as the signal transducers and activator of transcription (STAT) proteins (Zhu J. 2010). A direct role in bridging distant regulatory elements has been demonstrated for GATA3 at Th2 cytokine loci (Spilianakis and Flavell, 2004). GATA3 is the Th2 master regulator (Zhu J．2010, Sung-Yun. 2004, Zhu J. 2004, Zheng W. 1997, Zhang DH. 1997), but it also plays important roles in multiple steps of CD4 T cell development (Ho IC. 2009). GATA3 can act as pioneer factors by initiating local chromatin opening and allowing the recruitment of other transcription factors to regulatory elements (Spilianakis and Flavell, 2004). Th2 differentiation is completely abolished both in vitro and in vivo when GATA3 is conditionally deleted in peripheral CD4 T cells (Zhu J. 2004, Pai SY. 2004). GATA-3 mRNA expression also increased in patients with SLE, compared with the healthy control groups (Zheng H. 2015, Sonia GR. 2012).
How It Is Measured or Detected
GATA3 mRNA in CD4 T cells can be detected by Real-time PCR (RT-PCR) (Lambert KC. 2005, Kurata H. 1999, Zhu J. 2001).
Domain of Applicability
Involvement of GATA3 in Th2 cell development through ER is common in humans, rodents, and other mammalian species (Ho IC. 2009). protein sequence conservation between all six vertebrate members (mouse, human, dog, cow, armadillo, capuchin and opossum) identifies GATA3 as having the highest sequence similarity with both its GATA paralogs and orthologs, suggesting that it may be closest to the ancestral mammalian GATA factor (Tremblay M. 2018).
