Activation of RANKL-induced osteoclasts and memory T lymphocytes by Porphyromonas gingivalis is serotype dependant
(Blackwell Munksgaard, 2014)Aim Destructive periodontitis is associated with a Th1-Th17 immune response and activation of RANKL-induced osteoclasts. In addition, Porphyromonas gingivalis K1 and K2 serotypes induce a strong Th1-Th17 response. This ... -
Alveolar bone resorption and TH1/TH17-associated immune response triggered during Aggregatibacter actinomycetemcomitans-induced experimental periodontitis are serotype-dependent
(Wiley-Blackwell, 2018)© 2018 American Academy of Periodontology. Background: Aggregatibacter actinomycetemcomitans expresses several virulence factors that may contribute to the pathogenesis of periodontitis. Based on the anti-genicity of the ... -
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 ... -
ATP Induces IL-1 beta Secretion in Neisseria gonorrhoeae-Infected Human Macrophages by a Mechanism Not Related to the NLRP3/ASC/Caspase-1 Axis
(Hindawi, 2016)Neisseria gonorrhoeae (Ngo) has developed multiple immune evasion mechanisms involving the innate and adaptive immune responses. Recent findings have reported that Ngo reduces the IL-1 beta secretion of infected human ... -
ATP Induces IL-1 β Secretion in Neisseria gonorrhoeae-Infected Human Macrophages by a Mechanism Not Related to the NLRP3/ASC/Caspase-1 Axis
(Hindawi Limited, 2016)© 2016 Killen Garciá et al.Neisseria gonorrhoeae (Ngo) has developed multiple immune evasion mechanisms involving the innate and adaptive immune responses. Recent findings have reported that Ngo reduces the IL-1β secretion ... -
Biochemical markers of bone metabolism in gingival crevicular fluid during early orthodontic tooth movement
(The EH Angle Education and Research Foundation, 2013)Objective: To evaluate the expression of an activator of nuclear factor-kappa (RANK), osteoprotegerin (OPG), osteopontin (OPN), and transforming growth factor ß1 (TGF-ß1) in gingival crevicular fluid (GCF) of teeth ... -
Bone resorptive activity in symptomatic and asymptomatic apical lesions of endodontic origin
(Springer, 2017)The aim of this study is to assess the levels and diagnostic accuracy of a set of bone resorption biomarkers, including TRAP-5, RANKL, and OPG in symptomatic and asymptomatic apical lesions and controls. Apical tissues ... -
CCL2 Inhibits the Apoptosis Program Induced by Growth Factor Deprivation, Rescuing Functional T Cells
(American Association of Immunologists, 2007)The precise mechanisms involved in the switch between the clonal expansion and contraction phases of a CD8 T cell response remain to be fully elucidated. One of the mechanisms implicated in the contraction phase is ... -
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 ... -
Development of a self report questionnaire designed for population based surveillance of gingivitis in adolescents: assessment of content validity and reliability
(Universidade de São Paulo, 2017)The major infectious diseases in Chile encompass the periodontal diseases, with a combined prevalence that rises up to 90% of the population. Thus, the population-based surveillance of periodontal diseases plays a central ... -

Differential cytokine expression by human dendritic cells in response to different Porphyromonas gingivalis capsular serotypes
(2009)Aim: Capsular polysaccharides play an important role in the virulence of Gram-positive and Gram-negative bacteria. In Porphyromonas gingivalis, six serotypes have been described based on capsular antigenicity and its ... -
Differential expression of CC chemokines (CCLs) and receptors (CCRs) by human T lymphocytes in response to different Aggregatibacter actinomycetemcomitans serotypes
(Univ Sao Paulo Fac Odontologia Bauru, 2015)In Aggregatibacter actinomycetemcomitans, different serotypes have been described based on LPS antigenicity. Recently, our research group has reported a differential immunogenicity when T lymphocytes were stimulated with ... -

Differential human Th22-lymphocyte response triggered by Aggregatibacter actinomycetemcomitans serotypes
(Elsevier Ltd, 2017)© 2017 Elsevier Ltd Objective In Aggregatibacter actinomycetemcomitans, different serotypes have been described based on lipopolysaccharide (LPS) antigenicity. When T lymphocytes were stimulated with these serotypes, ... -
Distinct human T-lymphocyte responses triggered by Porphyromonas gingivalis capsular serotypes
(John Wiley & Sons, 2014)Aim: Porphyromonas gingivalis can synthesize an extracellular capsule and different serotypes have been described based on capsular antigenicity. On dendritic cells (DCs), the type of capsule present plays a role on the ... -
Does the Use of a ''walking bleaching'' technique increase bone resorption markers?
(Indiana University School of Dentistry, 2018)© 2018 Operative Dentistry. Objective: This randomized clinical trial evaluated the effect of 35% hydrogen peroxide in comparison with 37% carbamide peroxide in a nonvital bleaching technique of ''walking bleaching'' (four ...
