    • Rosas Chuñil, Carlos Alberto; Sinning Opazo, Mariana; Ferreira Vigouroux, Luis Arturo; Fuenzalida Bunster, Luz; Lemus Acuña, Luis (BioMed Central, 2014)
      Background: During the last few years it has been shown in several laboratories that Celecoxib (Cx), a non-steroidal anti-inflammatory agent (NSAID) normally used for pain and arthritis, mediates antitumor and antiangiogenic ...
    • Abello Cáceres, Paula; Pizarro Bauerle, Javier; Rosas Chuñil, Carlos Alberto; Maldonado, Ismael; Aguilar Guzmán, Lorena Andrea; González Guevara, Carlos Mauricio; Ramírez Toloza, Galia Andrea; Ferreira Parker, Jorge; Ferreira Vigouroux, Luis Arturo (2016)
      Background: For several decades now an antagonism between Trypanosoma cruzi infection and tumor development has been detected. The molecular basis of this phenomenon remained basically unknown until our proposal that T. ...
    • Smith Schuster, Pedro; Zurita Arevalo, Livio; Canale Montenegro, Francisco; Ferreira Vigouroux, Luis Arturo; Toro Guzmán, Haroldo (1994)
      An ELISA to detect circulating antibodies against K99 pili, a major attachment factor to intestinal epithelial cells of Escherichia coli in calves, was performed. Two methods of K99 pili purification were attempted. Best ...
    • Aguilera, Raquel; Saffie, Carlos; Tittarelli, Andrés; González Bergas, Fermín; Ramírez Fernández, Marcos; Reyes, Diego; Pereda, Cristián; Hevia, Daniel; García, Tamara; Salazar, Lorena; Ferreira Vigouroux, Luis Arturo; Hermoso Ramello, Marcela; Mendoza Naranjo, Ariadna; Ferrada, Carlos; Garrido, Paola; López Nitsche, Mercedes; Salazar Onfray, Flavio (AMER ASSOC CANCER RESEARCH, 2011-04-15)
      Purpose: This study characterizes, biologically and clinically, a novel type of dendritic cells (DC) produced in the short term and called tumor antigen–presenting cells (TAPCells). In particular, we identified factors ...
    • Aguilar Guzmán, Lorena Andrea; Lobos González, Lorena; Rosas, Carlos; Vallejos, Gerardo; Falcón, Cristián; Sosoniuk Roche, Eduardo Rodrigo; Coddou, Francisca; Leyton Campos, Lisette; Lemus Acuña, Luis; Quest, Andrew F. G.; Ferreira Vigouroux, Luis Arturo (2014)
      Immune-based anti-tumor or anti-angiogenic therapies hold considerable promise for the treatment of cancer. The first approach seeks to activate tumor antigen-specific T lymphocytes while, the second, delays tumor growth ...
    • Castillo, Christian; Ramírez Toloza, Galia; Valck Calderón, Carolina Eliana; Aguilar, Lorena; Maldonado, Ismael; Rosas, Carlos; Galanti Garrone, Norbel; Kemmerling Weis, Ulrike; Ferreira Vigouroux, Luis Arturo (PLOS Neglected Tropical Diseases, 2013)
      Background: 9 million people are infected with Trypanosoma cruzi in Latin America, plus more than 300,000 in the United States, Canada, Europe, Australia, and Japan. Approximately 30% of infected individuals develop ...
    • Ramírez Tolosa, Galia; Avello Cáceres, Paula; Ferreira Vigouroux, Luis Arturo (Frontiers Media, 2016)
      Eight to 10 million people in 21 endemic countries are infected with Trypanosoma cruzi. However, only 30% of those infected develop symptoms of Chagas' disease, a chronic, neglected tropical disease worldwide. Similar to ...
    • Maya Arango, Juan; Cassels Niven, Bruce; Iturriaga-Vásquez, Patricio; Ferreira, Jorge; Faúndez, Mario; Galanti Garrone, Norbel; Ferreira Vigouroux, Luis Arturo; Morello Casté, Antonio (2007)
      Current knowledge of the biochemistry of Trypanosonta cruzi has led to the development of new drugs and the understanding of their mode of action. Some trypanocidal drugs such as nifurtimox and benznidazole act through ...
    • Moreau, Christophe P.; Bally, Isabelle; Iannello, Marina; Laffly, Emmanuelle; Chouquet, Anne; Ferreira Vigouroux, Luis Arturo; Thielens, Nicole M.; Gaboriaud, Christine (2016)
      Calreticulin (CRT) is a multifaceted protein of 45k Da, early discovered as a receptor of the collagen-like regions of the complement C1q protein and better known as an ER chaperone protein, essential in calcium metabolism. ...
    • Peña Álvarez, Jaime; Teneb, Jaime; Maldonado Fuentes, Ismael; Weinberger Stange, Katherine; Rosas Chuñil, Carlos; Lemus Acuña, David; Valck Calderón, Carolina; Olivera Nappa, Álvaro; Asenjo de Leuze, Juan; Ferreira Vigouroux, Luis Arturo (Elsevier, 2020)
      Microbes have developed mechanisms to resist the host immune defenses and some elicit antitumor immune responses. About 6 million people are infected with Trypanosoma cruzi, the protozoan agent of Chagas' disease, the sixth ...
    • Ramírez Toloza, Galia; Sosoniuk Roche, Eduardo; Valck Calderón, Carolina; Aguilar Guzmán, Lorena; Ferreira, Viviana; Ferreira Vigouroux, Luis (Elsevier, 2020)
      To successfully infect, Trypanosome cruzi evades and modulates the host immune response. T. cruzi calreticulin (TcCalr) is a multifunctional, endoplasmic reticulum (ER)-resident chaperone that, translocated to the external ...
    • Ramírez Toloza, Galia; Ferreira Vigouroux, Luis Arturo (Frontiers media SA, 2017)
      American Trypanosomiasis is an important neglected reemerging tropical parasitism, infecting about 8 million people worldwide. Its agent, Trypanosoma cruzi, exhibits multiple mechanisms to evade the host immune response ...
    • Pujol, Myriam; Castillo, Francisca; Álvarez, Carla; Rojas, Camila; Borie Polanco, Consuelo; Ferreira Vigouroux, Luis Arturo; Vernal Astudillo, Rolando (Biomed Central Ltd., 2017)
      Brucella canis is a small intracellular Gram-negative bacterium whose primary host is the dog, but it also can cause mild human brucellosis. One of the main causes of an inefficient immune response against other species ...
