An Introduction to Adherens Junctions: From Molecular Mechanisms to Tissue Development and Disease

adherens junctions from molecular mechanisms to tissue development and disease harris tony

Cell-cell adhesion is fundamental for the development and homeostasis of animal tissues and organs. The core complex is formed from transmembrane cell-cell adhesion molecules, cadherins, and adaptor molecules, the catenins, that link to cytoskeletal and regulatory networks within the cell. This complex can be considered over a wide range of biological organization, from atoms to molecules, protein complexes, molecular networks, cells, tissues, and overall animal development. Cite this chapter as: Harris T. Mutating residues implicated in phosphatidic acid binding revealed a possible role in Bazooka localization and function.

As cells form during cellularization, basally localized Bazooka undergoes basal-to-apical transport. The cytoskeleton and classical cadherin adhesions; Siew Ping Han and Alpha Yap 7. The core complex is formed from transmembrane cell-cell adhesion molecules, cadherins, and adaptor molecules, the catenins, that link to cytoskeletal and regulatory networks within the cell. Adherens junctions and pathogens entry; Georgios Nikitas and Pascale Cossart Index. Adherens junctions and stem cells; Terry Lechler 16. We report two mechanisms acting in concert to displace Bazooka from the basolateral membrane.

Adherens junctions and cancer; Valeri Vasioukhin 17. . These include physical anchoring to the niche, control of proliferation and division orientation, regulation of signaling cascades and of differentiation. In epithelia, it functions as a plasma membrane landmark to organize the apical domain. However, it is unclear how Bazooka becomes polarized. In this review, a number of model stem cell systems that highlight various functions of adherens junctions are discussed.

Adherens junctions during cell migration; Sandrine Etienne-Manneville 11. These data implicate a closer connection between Bazooka and membrane lipids than previously recognized. Studying the molecular bases of cell and tissue development Our lab studies how animal tissues are built. Proper epithelial structure is critical for guiding embryo development and directing adult functions e. We are investigating the signals upstream of these circuits, the interplay among the core members of the circuits, and the downstream effects of the circuits on cytoskeletal networks and adherens junctions for initial cell formation and polarization, and for subsequent embryo morphogenesis. Our work complements recent findings in Caenorhabditis elegans and thus suggests the coupling of transport and dispersion is a common protein polarization strategy. This complex can be considered over a wide range of biological organization, from atoms to molecules, protein complexes, molecular networks, cells, tissues, and overall animal development.

These stem cells often live in specialized anatomical areas, called niches. Cite this chapter as: Lechler T. The three-dimensional structure of the cadherin-catenin complex; Noboru Ishiyama and Mitsuhiko Ikura 4. While niches can be complex, most involve cell-cell interactions that are mediated by adherens junctions. Increasing or decreasing levels of diacylglycerol kinase or phospholipase D-enzymes that produce phosphatidic acid-reveal a role for phosphatidic acid in Bazooka embryonic epithelial activity but not its localization. We use confocal microscopy, Drosophila genetics, molecular biology, targeted proteomics, and mathematical simulations to determine the molecular bases of how epithelial cells are first formed and then re-shaped during development. This analysis demonstrates that the roles of adherens junctions are surprisingly varied and integrated with both the anatomy and the physiology of the tissue.

Epithelia are sheets of adherent cells that form our skin and coat our organs. This complex can be considered over a wide range of biological organization, from atoms to molecules, protein complexes, molecular networks, cells, tissues, and overall animal development. Immunoglobulin superfamily receptors and adherens junctions; Yohei Shimono, Yoshiyuki Rikitake, Kenji Mandai, Masahiro Mori and Yoshimi Takai 8. In addition, Bazooka has been shown to interact with phosphoinositides. Adherens junctions and cadherins in Drosophila development; Annalisa Letizia and Marta Llimargas 12. Overall, our work aims to define core molecular mechanisms of cellular and epithelial morphogenesis in animals.

A diverse array of functions have been attributed to adherens junctions in stem cell biology. Cadherin function during Xenopus gastrulation; Rudolf Winklbauer 14. The core complex is formed from transmembrane cell—cell adhesion molecules, cadherins, and adaptor molecules, the catenins, that link to cytoskeletal and regulatory networks within the cell. Valuable for both newcomers and experts in the field, this book offers a comprehensive resource for the research laboratory and a teaching tool for advanced undergraduate and graduate courses in cell and developmental biology. We are particularly interested in the cross-talk between different molecular circuits and machinery responsible for epithelial development polarity, adhesion, cytoskeletal and membrane trafficking complexes.
