      Bugueño Valdebenito, Isaac Maximiliano (Universidad de Chile, 2014)
      La periodontitis es una enfermedad infecciosa multifactorial, caracterizada por una respuesta inflamatoria exacerbada que produce la destrucción de las estructuras que dan soporte al diente, incluyendo la encía, el ...

      Díaz, Leonor; Hoare, Anilei; Soto, Cristopher; Bugueño, Isaac; Silva Steffens, Nora; Dutzan Muñoz, Nicolás; Venegas, Darna; Salinas, Daniela; Pérez Donoso, José; Gamonal Aravena, Jorge Antonio; Bravo Rodríguez, Denisse (Elsevier, 2015)
      Virulence factors on the surface of Porphyromonas gingivalis constitute the first line of interaction with host cells and contribute to immune modulation and periodontitis progression. In order to characterize surface ...
    • Characterization of progressive periodontal lesions in chronic periodontitis patients: levels of chemokines, ... 
      Silva Steffens, Nora; Dutzan Muñoz, Nicolás; Hernández Ríos, Emma; Dezerega Piwonka, Andrea; Rivera Escobar, Oriana; Aguillón Gutiérrez, Juan Carlos; Aravena, Octavio; Lastres, Pedro; Pozo, Patricia; Vernal Astudillo, Rolando; Gamonal Aravena, Jorge Antonio (Blackwell, 2008)
      Background and aims: Periodontitis is an infection with an episodic nature of tissue support destruction. The aim of this work was to determine the levels of chemokines, cytokines, matrix metalloproteinase-13, periodontal ...
    • Establishment and Stability of the Murine Oral Microbiome 
      Abusleme Ramos, Loreto Andrea; O'Gorman, H.; Dutzan Muñoz, Nicolás; Greenwell-Wild, T.; Moutsopoulos, N. M. (SAGE, 2020)
      Commensal microbiomes exert critical functions at barrier sites. In particular, establishment of the commensal microbiome after birth dictates immune functionality and tissue homeostasis at mucosal surfaces. To investigate ...
    • Host response mechanisms in periodontal diseases 
      Silva, Nora; Abusleme Ramos, Loreto Andrea; Bravo, Denisse; Dutzan Muñoz, Nicolás; García Sesnich, Jocelyn; Vernal Astudillo, Rolando; Hernández, Marcela; Gamonal Aravena, Jorge Antonio (Univ Sao Paulo Fac Odontologia Bauru, 2015)
      Periodontal diseases usually refer to common inflammatory disorders known as gingivitis and periodontitis, which are caused by a pathogenic microbiota in the subgingival biofilm, including Porphyromonas gingivalis, ...
    • Levels of Interferon-Gamma and Transcription Factor T-Bet in Progressive Periodontal Lesions in Patients ... 
      Dutzan Muñoz, Nicolás; Vernal Astudillo, Rolando; Hernández Ríos, Emma; Dezerega Piwonka, Andrea; Rivera Escobar, Oriana; Silva Steffens, Nora; Aguillón Gutiérrez, Juan Carlos; Puente Piccardo, Javier; Pozo, Patricia; Gamonal Aravena, Jorge Antonio (2009-02)
      Background: Periodontitis is an infection with an episodic pattern of tissue-support destruction. During the generation of a primary CD4+ T helper 1 (Th1) response, interferon-gamma (IFN-g) acts as a positive regulator ...
    • Levels of interleukin-17 in gingival crevicular fluid and in supernatants of cellular cultures of gingival ... 
      Vernal Astudillo, Rolando; Dutzan Muñoz, Nicolás; Chaparro, Alejandra; Puente Piccardo, Javier; Valenzuela, María Antonieta; Gamonal Aravena, Jorge Antonio (BLACKWELL MUNKSGAARD, 2005-04)
      Background and Aims: Interleukin-17 (IL-17) is a T-cell-derived cytokine that may play an important role in the initiation or maintenance of the pro-inflammatory response and has recently been found to stimulate osteoclastic ...
    • Melanoma cell lysate induces CCR7 expression and in vivo migration to draining lymph nodes of therapeutic ... 
      González Bergas, Fermín; Ortiz, Carolina; Reyes Rojas, Montserrat; Dutzan Muñoz, Nicolás; Patel, Vyomesh; Pereda, Cristián; Gleisner Muñoz, María Alejandra; López Nitsche, Mercedes; Gutkind, J. Silvio; Salazar Onfray, Flavio (John Wiley & Sons Ltd,, 2014)
      We have previously reported a novel method for the production of tumour-antigen-presenting cells (referred to as TAPCells) that are currently being used in cancer therapy, using an allogeneic melanomaderived cell lysate ...
    • Monocyte chemotactic protein-3: possible involvement in apical periodontitis chemotaxis 
      Dezerega Piwonka, Andrea; Osorio Alfaro, Constanza; Mardones Peñailillo, Jeannette Isabel; Mundi, V.; Dutzan Muñoz, Nicolás; Franco Martínez, María Eugenia; Gamonal Aravena, Jorge Antonio; Oyarzún Droguett, Alejandro; Overall, M. C.; Hernández Ríos, Emma (John Wiley & Sons, 2010-10)
      Aim  To study the expression of monocyte chemotactic protein-3 (MCP-3, also known as chemokine CCL-7) in tissue from apical lesions (AL) and to associate MCP-3 expression with symptomatic or asymptomatic apical ...
    • Niveles de Interleuquina-17 en el Fluido Gingival Crevicular y en Cultivos Celulares de Leucocitos Infiltrantes ... 
      Dutzan Muñoz, Nicolás (Universidad de Chile, 2003)
      La periodontitis es una enfermedad infecciosa de naturaleza inflamatoria, que involucra una respuesta inmune del hospedero y que se caracteriza por la destrucción de los tejidos de inserción del diente. Numerosos estudios ...
    • Presencia de Linfocitos T Reguladores en Periodontitis Crónica 
      Carré, L.; Franco Martínez, María Eugenia; Henríquez, L.; García Sesnich, Jocelyn; Dutzan Muñoz, Nicolás; Aguillón Gutiérrez, Juan Carlos; Gamonal Aravena, Jorge Antonio (Sociedad de Periodoncia de Chile., 2010-12)
