Lineage Diversion of T Cell Receptor Transgenic Thymocytes Revealed by Lineage Fate Mapping

BACKGROUND The binding of the T cell receptor (TCR) to major histocompatibility complex (MHC) molecules in the thymus determines fates of TCRalphabeta lymphocytes that subsequently home to secondary lymphoid tissue. TCR transgenic models have been used to study thymic selection and lineage commitment. Most TCR transgenic mice express the rearranged TCRalphabeta prematurely at the double negativ...

T-cell lineage fate: Instructed by receptor signals?

Mechanisms of lineage choice represent a challenging problem in developmental biology. Recent studies have shown that different T-cell receptor signals can affect CD4 or CD8 lineage choice. Thus, all the ingredients for instructive mechanisms of lineage fate are in place but other mechanisms cannot be completely ruled out.

Mast cell diversion of T-lineage precursor cells by the essential T-lineage transcription factor GATA-3

GATA-3 is essential for T cell development from the earliest stages. However, highly abundant GATA-3 can drive T-lineage precursors to a non-T fate, depending on Notch signaling and developmental stage. GATA-3 overexpression blocked pro-T cell survival when Notch-Delta signals were present, but enhanced viability in their absence. In double-negative (DN1) and DN2 but not DN3 fetal thymocytes, G...

T cell receptor–instructed αβ versus γδ lineage commitment revealed by single-cell analysis

alphabeta and gammadelta T cell lineages develop in the thymus from a common precursor. It is unclear at which stage of development commitment to these lineages takes place and in which way T cell receptor signaling contributes to the process. Recently, it was demonstrated that strong TCR signals favor gammadelta lineage development, whereas weaker TCR signals promote alphabeta lineage fate. Tw...

Multilayered specification of the T-cell lineage fate.

T-cell development from stem cells has provided a highly accessible and detailed view of the regulatory processes that can go into the choice of a cell fate in a postembryonic, stem cell-based system. But it has been a view from the outside. The problems in understanding the regulatory basis for this lineage choice begin with the fact that too many transcription factors are needed to provide cr...
