    • Capsular-defective Porphyromonas gingivalis mutant strains induce less alveolar bone resorption than W50 ... 
      Monasterio, Gustavo; Fernández, Baltasar; Castillo, Francisca; Rojas, Carolina; Cafferata, Emilio A.; Rojas, Leticia; Alvarez, Carla; Fernández, Alejandra; Hernández, Marcela; Bravo, Denisse; Vernal Astudillo, Rolando (Wiley-Blackwell, 2019)
      Background: Encapsulation of Porphyromonas gingivalis has been demonstrated as responsible of several host immunological changes, which have been associated with the pathogenesis of periodontitis. Using a murine model of ...
    • CD4+Foxp3+T regulatory cells promote transplantation tolerance by modulating effector CD4+ T cells in a ... 
      Campos-Mora, Mauricio; Contreras-Kallens, Pamina; Gálvez-Jirón, Felipe; Rojas, Masyelly; Rojas, Carolina; Refisch, Aarón; Cerda, Oscar; Pino-Lagos, Karina (Frontiers Media S.A., 2019)
      Copyright © 2019 Campos-Mora, Contreras-Kallens, Gálvez-Jirón, Rojas, Rojas, Refisch, Cerda and Pino-Lagos.Several mechanisms of immune suppression have been attributed to Foxp3+ T regulatory cells (Treg) including modulation ...
    • Humanized mouse models for the study of periodontitis: An opportunity to elucidate unresolved aspects of ... 
      Rojas, Carolina; García, Michelle P.; Polanco, Alan F.; González Osuna, Luis; Sierra Cristancho, Alfredo José; Melgar Rodríguez, Samanta Azucena; Cafferata Chea, Emilio Alfredo; Vernal Astudillo, Rolando Marcelo (Frontiers Media, 2021)
      Periodontitis is an oral inflammatory disease in which the polymicrobial synergy and dysbiosis of the subgingival microbiota trigger a deregulated host immune response, that leads to the breakdown of tooth-supporting ...
    • IL-22–expressing CD4 + AhR + T lymphocytes are associated with RANKL-mediated alveolar bone resorption ... 
      Monasterio, Gustavo; Budini, Victoria; Fernández, Baltasar; Castillo, Francisca; Rojas, Carolina; Alvarez, Carla; Cafferata, Emilio A.; Vicencio, Emiliano; Cortés, Bastián I.; Cortez, Cristian; Vernal Astudillo, Rolando (Blackwell Munksgaard, 2019)
      Background and Objective: Over the past few years, the importance of interleukin-22 (IL-22) and T-helper (Th)22 lymphocytes in the pathogenesis of periodontitis has become apparent; however, there are still aspects that ...
    • Increased nuclear β-catenin expression in oral potentially malignant lesions: A marker of epithelial dysplasia 
      Reyes, Montserrat; Rojas Alcayaga, Gonzalo; Maturana, Andrea; Aitken Saavedra, Juan; Rojas, Carolina; Ortega, Ana (Medicina Oral, Patologia Oral y Cirugia Bucal, 2015)
      Background: Deregulation of β-catenin is associated with malignant transformation; however, its relationship with potentially malignant and malignant oral processes is not fully understood. The aim of this study was to ...

      Armijo Farías, Alexis Nicolás (Universidad de Chile, 2022)
      Los humedales costeros son ecosistemas dinámicos de alto valor natural, cultural y económico. Se caracterizan por albergar gran biodiversidad de flora y fauna, además de proveer servicios ecosistémicos. Sin embargo, se han ...
    • Natural Killer T (NKT) cells and periodontitis: potential regulatory role of NKT10 cells 
      Melgar Rodríguez, Samanta Azucena; Cafferata Chea, Emilio Alfredo; Díaz, Nicolás I.; Peña, Miguel A.; González Osuna, Luis; Rojas, Carolina; Sierra Cristancho, Alfredo José; Cárdenas, Angélica M.; Díaz Zúñiga, Jaime; Vernal Astudillo, Rolando Marcelo (Hindawi, 2021)
      Natural killer T (NKT) cells constitute a unique subset of T lymphocytes characterized by specifically interacting with antigenic glycolipids conjugated to the CD1d receptor on antigen-presenting cells. Functionally, NKT ...
