Summary
Adherens junctions (AJs) and cadherins are crucial for animal development, maintaining tissue integrity and regulating cell behaviors. Studies in Drosophila reveal their essential roles in morphogenesis and cellular processes throughout development.
Area of Science:
- Developmental Biology
- Cell Biology
- Genetics
Background:
- Drosophila is a key model organism for studying developmental mechanisms.
- Adherens junctions (AJs) and cadherins are vital cell-cell adhesion components.
- Understanding AJ function is crucial for comprehending tissue development and homeostasis.
Purpose of the Study:
- To summarize the essential roles of Adherens Junctions (AJs) and cadherins in Drosophila morphogenesis.
- To highlight the contribution of Drosophila as a model system for AJ research.
- To illustrate the complex regulation and interactions of AJs during development.
Main Methods:
- Functional analysis of mutants for core AJ components, including Drosophila DE-cadherin.
- In vivo studies within the context of a whole organism.
- Integration of diverse techniques and approaches to study AJ requirements.
Main Results:
- AJs and cadherins are indispensable for nearly all stages of Drosophila development.
- AJs maintain tissue integrity while enabling tissue remodeling and homeostasis.
- AJs regulate critical cellular processes like cell shape, polarity, cell sorting, division orientation, and cell rearrangements.
Conclusions:
- Drosophila Adherens Junctions (AJs) and cadherins are fundamental for morphogenesis.
- Precise control over AJ organization and turnover is critical for developmental processes.
- AJs interact intricately with the cytoskeleton, signaling pathways, and intracellular trafficking to execute their functions.

01:24Adherens Junctions
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.

01:19Cadherins in Tissue Organization
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.

01:25Structure of Cadherins
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 diversity of cadherins...
01:03Anchoring Junctions
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:...
01:05Desmosomes
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...
01:26Tension Response at Adherens Junctions
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.
