Vegetative Hyphal Fusion in Filamentous Fungi
Nick D. Read and M. Gabriela Roca
The formation of channels between fungal hyphae by self fusion is a defining feature of filamentous fungi, and results in the fungal colony being a complex interconnected network of hyphae. Du...
Sieve-Pore Plugging Mechanisms
Aart J.E. van Bel
Sieve tubes seem to dispose of diverse mechanisms which are able to seal or plug sieve pores - very specialized and evolutionarily transformed cell-cell channels - in response to injury. Two maj...
Cytonemes As Cell-Cell Channels in Human Blood Cells
Svetlana Ivanovna Galkina, Anatoly Georgievich Bogdanov, Georgy Natanovich Davidovich and Galina Fedorovna Sud’ina
Human blood cell similar to embryonic and nerve cells can extend thin and very long exten- sions having the same diameter along the entire length called cytonemes. Cytonemes were shown to connect...
Plasmodesmata: Cell-Cell Channels in Plants
Yoselin Benitez Alfonso, Laurence Cantrill and David Jackson
Plasmodesmata (PD) permit diffusion of small metabolites and proteins, as well as active trafficking of specific RNAs and proteins. Their structure and distribution vary according to species, ce...
Channels across Endothelial Cells
Radu V. Stan
The evolution of multicellular organisms entailed the formation of biological compartments separated by epithelial cellular barriers. As a consequence, strategies have evolved to move/ exchange m...
Tunneling Nanotubes: Membranous Channels between Animal Cells
Hans-Hermann Gerdes and Amin Rustom
Intercellular communication is a major requirement for the development and maintainance of multicellular organisms. Diverse mechanisms for the exchange of signals between cells during evolution ...
Viral Movement Proteins Induce Tubule Formation in Plant and Insect Cells
Jan W.M. van Lent and Corinne Schmitt-Keichinger
Plant viruses move from cell to cell through plasmodesmata, which are complex gatable pores in the cell wall. As plasmodesmata normally allow the diffusion of only small molecules, virus movemen...
Molecular Transfers through Transient Lymphoid Cell-Cell Channels
Mary Poupot, Julie Gertner and Jean-Jacques Fournié
Intercellular communication is inherent to life, and has evolved with extremely diversified forms from prokaryotes to the most sophisticated multicellular eukaryotes. Haematopoietic cells from m...
Fusome as a Cell-Cell Communication Channel of Drosophila Ovarian Cyst
Jean-René Huynh
In most animal species, female and male gametes are produced within clusters of germ cells which share a common cytoplasm through cell-cell channels. In Drosophila ovaries, these cells synchronise the...
Actin and Myosin VIII in Plant Cell-Cell Channels
Jozef Samaj, Nigel Chaffey, Uday Tirlapur, Jan Jasik, Andrej Hlavacka, Zhan Feng Cui, Dieter Volkmann, Diedrik Menzel and Frantisek Baluska
Plasmodesmata (PD) are cell-cell channels interconnecting all the cells of the plant body into a huge syncytium, which makes plants ‘supracellular’ organisms. Recent studies have clearly revealed ...
Cytoplasmic Bridges as Cell-Cell Channels of Germ Cells
Sami Ventelä
Transient intercellular bridges are seen between a wide variety of cells before the completion of cytokinesis.1 However, these are distinct from stable intercellular bridges that remain persistent aft...
Virological Synapse for Cell-Cell Spread of Viruses
Eduardo Garcia and Vincent Piguet
Cell-to-cell spread of retroviruses via virological synapse (VS) contributes to overall progression of disease. VS are specialized pathogen-induced cellular structures that facilitate cell-to-cell tra...
Cell-Cell Fusion: Transient Channels Leading to Plasma Membrane Merger
William A. Mohler
Despite the diversity of intercellular connections that are the subject of this book, most eukaryotic cells retain their distinct character as mononucleated compartments. Their membranes describe ...
Cell-Cell Transport of Homeoproteins: With or Without Channels?
Alain Joliot and Alain Prochiantz
Homeoproteins are a class of transcription factors that have the unusual property of intercellular transfer, both in metaphytes and in metazoans. Here we discuss the cellular mechanisms and the fu...
Mating Cell-Cell Channels in Conjugating Bacteria
Elisabeth Grohmann
Conjugative plasmid transfer is the most important mechanism for bacteria to deliver and acquire genetic information to cope with rapidly changing environmental conditions. To transfer genetic inf...
The Tetrahymena Conjugation Junction
Eric S. Cole
Life History: Sexual and Asexual Reproduction Those who study ciliates have struggled over the years to establish a place in the pantheon of model organisms.1 Eukaryotic cell biologists have turned p...
Paracellular Pores in Endothelial Barriers
Luca Manzi and Gianfranco Bazzoni
The endothelium is an efficient barrier located at the boundary between vascular and perivascular compartments. However, it is also regarded to as a permeable filter that contains aqueous pores an...
Cell-Cell Movements of Transcription Factors in Plants
Alexis Maizel
In the last few years, the intercellular trafficking of regulatory proteins has emerged as a novel mechanism of cell-to-cell communication in plant development. Here I present a review of the document...
Cell-Cell Communication in Wood
J.R. Barnett
The sapwood of trees contains living cells in the form of ray and axial parenchyma. Communication between these cells is important in controlling the differentiation of xylem cells, movement of nutrie...
Gap Junctions: Cell-Cell Channels in Animals
Fabio Mammano
Gap junctions provide one of the most common forms of intercellular communication. The structures underlying these communicating cell junctions1 were soon resolved in membrane associated particles for...
TMV Movement Protein Targets Cell-Cell Channels in Plants and Prokaryotes: Possible Roles of Tubulin- and FtsZ-Based Cytoskeletons
Manfred Heinlein
Cell-to-cell communication in plants occurs via plasmodesmata (Pd), dynamic membrane-lined pores in the plant cell wall that provide symplasmic continuity between adjacent cells. Communication through...
Cytoplasmic Bridges in Volvox and Its Relatives
Harold J. Hoops, Ichiro Nishii and David L. Kirk
The volvocaceans are a closely related group of green flagellates that range in size and complexity from colonial forms that contain a small number of identical cells, to Volvox in which there is a di...
Cell-Cell Channels and Their Implications for Cell Theory
Frantisek Baluska*, Dieter Volkmann and Peter W. Barlow
Cells show diverse appearances and sizes, ranging from some 30 nanometers up to several meters in length. Besides the classical prokaryotic and eukaryotic cells, there are also very bizarre cells such...
