    • alpha (V) beta (3) Integrin regulates astrocyte reactivity 
      Lagos Cabre, Raúl; Álvarez, Álvaro; Kong, Milene; Burgos Bravo, Francesca; Cárdenas, Areli; Rojas Mancilla, Edgardo; Pérez Núñez, Ramón Daniel; Herrera Molina, Rodrigo; Rojas, Fabiola; Schneider, Pascal; Herrera-Marschitz Muller, Mario; Quest, Andrew F. G.; van Zundert, Brigitte; Leyton Campos, Lisette (BIOMED Central Ltd., 2017)
      Background: Neuroinflammation involves cytokine release, astrocyte reactivity and migration. Neuronal Thy-1 promotes DITNC1 astrocyte migration by engaging alpha(V)beta(3) Integrin and Syndecan-4. Primary astrocytes express ...
    • 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 ...
    • Integrin-mediated transactivation of P2X7R via hemichannel-dependent ATP release stimulates astrocyte migration 
      Álvarez, Álvaro; Lagos Cabré, Raúl; Kong, Milene; Cárdenas, Areli; Burgos Bravo, Francesca; Schneider, Pascal; Quest, Andrew F. G.; Leyton Campos, Lisette (Elsevier, 2016)
      Our previous reports indicate that ligand-induced alpha(v)beta(3) integrin and Syndecan-4 engagement increases focal adhesion formation and migration of astrocytes. Additionally, ligated integrins trigger ATP release through ...
    • 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 ...
    • Syndecan-4/PAR-3 signaling regulates focal adhesion dynamics in mesenchymal cells 
      Valdivia Hepp, Juan; Cárdenas, Areli; Brenet, Marianne; Maldonado, Horacio; Kong, Milene; Díaz Jara, Jorge; Burridge, Keith; Schneider, Pascal; San Martín, Alejandra; García Mata, Rafael; Quest, Andrew F. G.; Leyton, Lisette (BMC, 2020)
      Background: Syndecans regulate cell migration thus having key roles in scarring and wound healing processes. Our previous results have shown that Thy-1/CD90 can engage both alpha v beta 3 integrin and Syndecan-4 expressed ...
    • 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 ...
