Journal ArticleDOI
Identification of a tight junction–associated guanine nucleotide exchange factor that activates Rho and regulates paracellular permeability
Gaelle Benais-Pont,Anu Punn,Catalina Flores-Maldonado,Judith J. Eckert,Graça Raposo,Tom P. Fleming,Marcelino Cereijido,Maria S. Balda,Karl Matter +8 more
TL;DR: Data indicate that GEF-H1/Lfc is a component of TJs and functions in the regulation of epithelial permeability, as indicated by measuring transepithelial resistance and by immunofluorescence and freeze-fracture analysis.
Journal ArticleDOI
Multiple domains of occludin are involved in the regulation of paracellular permeability.
TL;DR: expression of chimeras containing at least one transmembrane domain of occludin resulted in an enhanced intracellular accumulation of claudin‐4, suggesting that the two proteins may cooperate in the regulation of paracellular permeability.
Journal ArticleDOI
Relationship between Na(+),K(+)-ATPase and cell attachment
TL;DR: It is suggested that there is a mechanism (P-->A) that transduces a blockade of the pump in a detachment of the cell from neighbors and substrate, in which Ma104 cells are faulty.
Journal ArticleDOI
Ouabain modulates epithelial cell tight junction
Isabel Larre,A. Lázaro,Rubén G. Contreras,Maria S. Balda,Karl Matter,Catalina Flores-Maldonado,Arturo Ponce,David Flores-Benitez,Ruth Rincon-Heredia,Teresita Padilla-Benavides,Aida Castillo,Liora Shoshani,Marcelino Cereijido +12 more
TL;DR: The theory that at low concentrations, ouabain acts as a modulator of cell–cell contacts at low, nontoxic levels is supported.
Journal ArticleDOI
New Diseases Derived or Associated with the Tight Junction
Marcelino Cereijido,Rubén G. Contreras,David Flores-Benitez,Catalina Flores-Maldonado,Isabel Larre,Agustín Ruíz,Liora Shoshani +6 more
TL;DR: The present article depicts the efforts being made to find pharmaceutical agents that would seal faulty TJs or release their grip to allow for the passage of large molecules through the upper respiratory and digestive tracts, such as insulin, thyroid, appetite-regulatory peptide, etc.
