Asociación de mayores niveles de RANKL y linfocitos T CD4+ en periodontitis
(Escuela de Odontología. Facultad de Salud. Universidad del Valle, 2004)Propósito: La periodontitis es una enfermedad infecciosa que involucra una sobre-respuesta inmune del hospedero y se caracteriza por la destrucción de los tejidos de soporte del diente.Durante su desarrollo se establece ... -
Caracterización de aislados clínicos de Porphyromonas gingivalis y su efecto en la viabilidad de células epiteliales gingivales
(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 ... -
Changes in lipopolysaccharide profile of Porphyromonas gingivalis clinical isolates correlate with changes in colony morphology and polymyxin B resistance
(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, cytokines, matrix metalloproteinase-13, periodontal pathogens and inflammatory cells
(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 ... -
Chemokine Monocyte Chemoattractant Protein-3 in Progressive Periodontal Lesions in Patients With Chronic Periodontitis
(American Academy of Periodontology, 2010-02)Background: Chemokines are central in the activation and direction of leukocyte subsets to target tissues. However, the monocyte chemoattractant protein-3 (MCP-3) has not been associated with chronic periodontitis. Chronic ... -
Cuantificación de células infiltrantes CD4+, CD8+ y CD19+ en el tejido gingival de individuos con periodontitis crónica
(Universidad de Chile, 2007)La periodontitis es una enfermedad inflamatoria del tejido periodontal, iniciada por el biofilm subgingival, que genera la destrucción progresiva de las estructuras de inserción dentaria. La naturaleza de la respuesta ... -
Establishment and Stability of the Murine Oral Microbiome
(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 ... -
Expresión de metaloproteinasa de matriz ectracelular-13 (MMP-13) en dientes con periodontitis apical asintomática
(Universidad de Chile, 2010)Introducción La periodontitis apical asintomática (PAa) es una respuesta inmunoinflamatoria local a la invasión microbiana de la pulpa, que resulta en la destrucción de los tejidos periapicales. La metaloproteinasa de ... -
Expresión de metaloproteinasas de matriz extracelular (MMPs) -2, -13 y -14 en dientes con periodontitis apical crónica y tejido periapical sano
(Universidad de Chile, 2009)Introducción La periodontitis apical crónica (PAC) es una patología inmunoinflamatoria caracterizada por destrucción ósea asociada a inflamación crónica y expresión de mediadores moleculares, dentro de los cuales ... -
High expression levels of receptor activator of nuclear factor-kappa B ligand associated with human chronic periodontitis are mainly secreted by CD4+ T lymphocytes
(American Academy of Periodontology, 2006-10)Background: Chronic periodontitis is an infectious disease characterized by alveolar bone destruction and teeth loss. Receptor activator of nuclear factor-kappa B ligand (RANKL) is an osteoclastogenic cytokine, a central ... -
Host response mechanisms in periodontal diseases
(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, ... -
Host-pathogen interactions in progressive chronic periodontitis
(Sage, 2011-10)Periodontitis is an infection characterized by the occurrence of supporting tissue destruction with an episodic nature. Disease progression is often determined by the loss of attachment level or alveolar bone, and sequential ... -
Incremento en los niveles de interleuquina-21 y su papel en la patogenia de los granulomas periapicales :|bFinanciado por: FONDECYT: 1090461, FONDECYT 1090046
(Universidad de Chile, 2010)Objetivo: Los granulomas periapicales (GPs) son lesiones de naturaleza infecciosa de origen pulpar caracterizados por la destrucción de los tejidos perirradiculares, en particular del hueso alveolar periapical. El fenotipo ... -
Interferon-g, Interleukins-6 and -4, and Factor XIII-A as Indirect Markers of the Classical and Alternative Macrophage Activation Pathways in Chronic Periodontitis
(Elsevier, 2014)Background: Macrophages account for 5% to 30% of the inflammatory infiltrate in periodontitis and are activated by the classic and alternative pathways. These pathways are identified by indirect markers, among which ... -
Interleukin-21 expression and its association with proinflammatory cytokines in untreated chronic periodontitis patients
(2012)Background: Interleukin-21 (IL-21) controls the differentiation of T-helper Th17 cells and induces the production of IL-17 in this T-cell subtype. The aim of this study is to determine the relative expression of IL-21 ... -
Levels of Interferon-Gamma and Transcription Factor T-Bet in Progressive Periodontal Lesions in Patients With Chronic Periodontitis
(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 tissue from patients with chronic periodontitis
(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 ... -
Levels of interleukin-21 in patients with untreated chronic periodontitis
(American Academy of Periodontology, 2011-10)BACKGROUND: A growing body of evidence suggested that interleukin (IL)-21 enhances the effector phase during T-cell responses. The aim of our study is to determine the levels of IL-21 in periodontal sites from patients ... -
