Cell term

The location/biological environment in which the event takes place.The biological context describes the location/biological environment in which the event takes place. For molecular/cellular events this would include the cellular context (if known), organ context, and species/life stage/sex for which the event is relevant. For tissue/organ events cellular context is not applicable. For individual/population events, the organ context is not applicable.

Key Event Components

The KE, as defined by a set structured ontology terms consisting of a biological process, object, and action with each term originating from one of 14 biological ontologies (Ives, et al., 2017; https://aopwiki.org/info_pages/2/info_linked_pages/7#List). Biological process describes dynamics of the underlying biological system (e.g., receptor signalling).Biological process describes dynamics of the underlying biological system (e.g., receptor signaling). The biological object is the subject of the perturbation (e.g., a specific biological receptor that is activated or inhibited). Action represents the direction of perturbation of this system (generally increased or decreased; e.g., ‘decreased’ in the case of a receptor that is inhibited to indicate a decrease in the signaling by that receptor). Note that when editing Event Components, clicking an existing Event Component from the Suggestions menu will autopopulate these fields, along with their source ID and description. To clear any fields before submitting the event component, use the 'Clear process,' 'Clear object,' or 'Clear action' buttons. If a desired term does not exist, a new term request may be made via Term Requests. Event components may not be edited; to edit an event component, remove the existing event component and create a new one using the terms that you wish to add.

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

A description of the type(s) of measurements that can be employed to evaluate the KE and the relative level of scientific confidence in those measurements.These can range from citation of specific validated test guidelines, citation of specific methods published in the peer reviewed literature, or outlines of a general protocol or approach (e.g., a protein may be measured by ELISA). Do not provide detailed protocols. More help

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

A description of the scientific basis for the indicated domains of applicability and the WoE calls (if provided). More help

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).
