    • Astrocytic α vβ 3 integrin inhibits neurite outgrowth and promotes retraction of neuronal processes by ... 
      Herrera Molina, Rodrigo; Frischknecht, Renato; Maldonado, Horacio; Seidenbecher, Constanze I.; Gundelfinger, Eckart D.; Hetz Flores, Claudio; Aylwin Ostale, María de la Luz; Schneider, Pascal; Quest, Andrew F. G.; Leyton Campos, Lisette (2012)
      Thy-1 is a membrane glycoprotein suggested to stabilize or inhibit growth of neuronal processes. However, its precise function has remained obscure, because its endogenous ligand is unknown. We previously showed that Thy-1 ...
    • ATP release due to Thy-1-integrin binding induces P2X7-mediated calcium entry required for focal adhesion formation 
      Henríquez, Mauricio; Herrera Molina, Rodrigo; Valdivia, Alejandra; Alvarez, Alvaro; Kong, Milene; Muñoz, Nicolás; Eisner, Verónica; Jaimovich Pérez, Enrique; Schneider, Pascal; Quest, Andrew F. G.; Leyton Campos, Lisette (2011)
      Thy-1, an abundant mammalian glycoprotein, interacts with avβ3 integrin and syndecan-4 in astrocytes and thus triggers signaling events that involve RhoA and its effector p160ROCK, thereby increasing astrocyte adhesion to ...
    • Direct Thy-1/alpha(V)beta(3) integrin interaction mediates neuron to astrocyte communication 
      Hermosilla, Tamara; Muñoz, Daniel; Herrera Molina, Rodrigo; Valdivia, Alejandra; Muñoz, Nicolás; Nham, Sang-Uk; Schneider, Pascal; Burridge, Keith; Quest, Andrew F. G.; Leyton Campos, Lisette (ELSEVIER, 2008-06)
      Thy-1 is an abundant neuronal glycoprotein of poorly defined function. We recently provided evidence indicating that Thy-1 clusters a beta(3)-containing integrin in astrocytes to induce tyrosine phosphorylation, RhoA ...
    • Intracellular ca2+ increases and connexin 43 hemichannel opening are necessary but not sufficient for ... 
      Lagos Cabré, Raúl; Brenet, Marianne; Díaz, Jorge; Pérez, Ramón D.; Pérez, Leonardo A.; Herrera Molina, Rodrigo; Quest, Andrew F. G.; Leyton Campos, Lisette (MDPI AG, 2018)
      © 2018 by the authors. Licensee MDPI, Basel, Switzerland. Under pro-inflammatory conditions, astrocytes become reactive and acquire a migratory phenotype. Our results show that hemichannels formed by connexin 43 (Cx43) ...
    • Neuronal Thy-1 induces astrocyte adhesion by engaging syndecan-4 in a cooperative interaction with alpha v ... 
      Ávalos, Ana María; Valdivia, A. D.; Muñoz, Nicolás; Herrera Molina, Rodrigo; Tapia Pineda, Julio; Lavandero González, Sergio; Chiong Lay, Mario; Burridge, Keith; Schneider, P.; Quest, Andrew F. G.; Leyton Campos, Lisette (COMPANY OF BIOLOGISTS LTD, 2009-10)
      Clustering of alpha v beta 3 integrin after interaction with the RGD-like integrin-binding sequence present in neuronal Thy-1 triggers formation of focal adhesions and stress fibers in astrocytes via RhoA activation. A ...
    • Neuronal Thy-1 induces astrocyte adhesion by engaging syndecan-4 in a cooperative interaction with αvβ3 ... 
      Avalos, Ana María; Valdivia, Alejandra D.; Muñoz, Nicolás; Herrera Molina, Rodrigo; Tapia, Julio C.; Lavandero González, Sergio; Chiong Lay, Mario; Burridge, Keith; Schneider, Pascal; Quest, Andrew F. G.; Leyton Campos, Lisette (2009)
      Clustering of αvβ3 integrin after interaction with the RGD-like integrin-binding sequence present in neuronal Thy-1 triggers formation of focal adhesions and stress fibers in astrocytes via RhoA activation. A putative ...
    • The Neuroplastin adhesion molecules: Key regulators of neuronal plasticity and synaptic function 
      Beesley, Philip W.; Herrera Molina, Rodrigo; Smalla, Karl-Heinz; Seidenbecher, Constanze (Blackwell, 2014)
      The Neuroplastins Np65 and Np55 are neuronal and synapseenriched immunoglobulin superfamily molecules that play important roles in a number of key neuronal and synaptic functions including, for Np65, cell adhesion. In ...
    • The signaling pathways underlying BDNF-induced Nrf2 hippocampal nuclear translocation involve ROS, RyR-Mediated ... 
      Bruna, Bárbara; Lobos, Pedro; Herrera Molina, Rodrigo; Hidalgo Tapia, María Cecilia; Paula Lima, Andrea; Adasme, Tatiana (Elsevier B.V., 2018)
      © 2018 Elsevier Inc. The neurotrophin Brain-Derived Neurotrophic Factor (BDNF) induces complex neuronal signaling cascades that are critical for the cellular changes underlying synaptic plasticity. These pathways include ...
    • Thy-1-mediated cell-cell contact induces astrocyte migration through the engagement of αVβ3 integrin and syndecan-4 
      Kong, Milene; Muñoz, Nicolás; Valdivia, Alejandra; Alvarez, Alvaro; Herrera Molina, Rodrigo; Cárdenas, Areli; Schneider, Pascal; Burridge, Keith; Quest, Andrew F. G.; Leyton Campos, Lisette (2013)
      Cell adhesion to the extracellular matrix proteins occurs through interactions with integrins that bind to Arg-Gly-Asp (RGD) tripeptides, and syndecan-4, which recognizes the heparin-binding domain of other proteins. Both ...
