This review details critical signals guiding T cell development in the thymus. It covers how these signals commit progenitors to T cells and generate diverse immune-supporting T cell subsets in mice and humans.
Area of Science:
- Immunology
- Developmental Biology
Background:
- T cell development is crucial for host immunity, occurring in the thymus.
- Bone marrow progenitors commit to T cell fate via signals like Notch signaling.
- Further differentiation generates diverse T cell subsets with specialized immune functions.
Purpose of the Study:
- To review critical signaling factors governing T cell development stages.
- To focus on transcriptional changes mediating T cell identity and diversity.
- To compare T cell development in mice and humans.
Main Methods:
- Literature review of studies on T cell differentiation.
- Analysis of signaling pathways involved in T cell commitment.
- Examination of transcriptional regulation in T cell subsets.
Main Results:
- Notch signaling is essential for initial T cell commitment.
- Specific thymic signals drive the generation of distinct T cell sublineages.
- Transcriptional programs define T cell identity and functional diversity.
Conclusions:
- Understanding thymic signaling is key to T cell development.
- Transcriptional changes are fundamental to T cell diversity and function.
- This review consolidates knowledge on T cell development in mice and humans.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
