Summary
E-cadherin is crucial for T cell development, aiding in the formation of immunological synapses and proper cell division during the critical β-selection stage. This molecule facilitates essential interactions within the thymic niche for T cell maturation.
Area of Science:
- Immunology
- Developmental Biology
- Cell Biology
Background:
- T cell development is a complex process involving precise stages like β-selection.
- The T cell receptor β (TCRβ) chain generation and acquisition of antigenic specificity occur during β-selection.
- Interactions with the thymic niche and stromal cells are vital for T cell development.
Purpose of the Study:
- To identify critical cues within the developing T cell niche that regulate T cell development.
- To investigate the role of E-cadherin in T cell development and β-selection.
Main Methods:
- Analysis of developing T cells within the thymic niche.
- Investigating the function of E-cadherin in mediating cell-cell interactions.
- Assessing the impact of E-cadherin on immunological synapse formation and mitotic spindle alignment.
Main Results:
- E-cadherin was identified as a critical cue in the T cell niche.
- E-cadherin mediates cell-cell interactions essential for T cell development.

01:19Cadherins in Tissue Organization
3.1K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

02:19The Spindle Assembly Checkpoint
3.2K
The spindle assembly checkpoint is a molecular surveillance mechanism ensuring the fidelity of chromosome segregation during anaphase. The checkpoint monitors the completion of all the prerequisite steps before chromosome segregation to determine whether the segregation process should proceed or be delayed.
Many proteins function together to control the spindle assembly checkpoint. Mutations affecting these proteins may allow cells to proceed into anaphase prematurely, resulting in the...

01:25Structure of Cadherins
3.4K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

01:32Cytoskeletal Coordination in Cell Migration
4.8K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...

2.4K
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.

3.7K
Spindle assembly occurs through three, often coexisting, pathways – the centrosome-mediated pathway, the chromatin-mediated pathway, and the microtubule-mediated pathway – collectively contributing to form a robust spindle apparatus.
In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a...
