Summary
Cadherin proteins like α-catenin and N-cadherin regulate neural progenitor behavior. Their roles in cell proliferation and differentiation are key to neocortical development and size in mammals.
Area of Science:
- Neuroscience
- Developmental Biology
- Evolutionary Biology
Background:
- The neocortex's expansion is crucial for vertebrate, especially mammalian, success.
- Neocortical development involves a neuroepithelium generating progenitors and neurons.
- Balancing progenitor production and differentiation impacts neocortical size.
Purpose of the Study:
- To review the function of cadherin adhesion proteins in neocortical development.
- To examine the roles of α-catenin and N-cadherin in neural progenitor regulation.
Main Methods:
- This is a review article, synthesizing existing research.
- Focuses on molecular mechanisms of cadherin proteins in neural development.
Main Results:
- Cadherins, specifically α-catenin and N-cadherin, are vital for the neural progenitor microenvironment.
- These proteins influence progenitor cell proliferation and neuronal differentiation.
- Their precise function impacts the regulation of neocortical size.
Conclusions:
- Cadherin-mediated cell adhesion is critical for controlling neural progenitor behavior.
- Understanding these mechanisms provides insight into neocortical evolution and size determination.

01:24Adherens Junctions
7.8K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

5.7K
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...

01:19Cadherins in Tissue Organization
4.6K
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.

32.4K
The complex three-dimensional arrangement of cells in any multicellular organism is defined and maintained by interactions of cells with each other and the extracellular matrix. Cell-cell junctions are specialized structures where the multi-protein complexes on one cell interact with the multi-protein complexes on another cell. These cell junctions are classified into three main types based on their function — occluding, anchoring, and gap junctions.

01:26Tension Response at Adherens Junctions
4.3K
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.
