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 ... -
Aggregatibacter actinomycetemcomitans Induces Autophagy in Human Junctional Epithelium Keratinocytes
(MDPI, 2020)The adverse environmental conditions found in the periodontium during periodontitis pathogenesis stimulate local autophagy responses, mainly due to a continuous inflammatory response against the dysbiotic subgingival ... -
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 β Secretion in Neisseria gonorrhoeae-Infected Human Macrophages by a Mechanism Not Related to the NLRP3/ASC/Caspase-1 Axis
(Hindawi Limited, 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-1𝛽 secretion of infected human ... -
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 ... -
Brucella canis induces canine CD4 + T cells multi-cytokine Th1/Th17 production via dendritic cell activation
(Elsevier, 2019)Brucella canis is a small intracellular Gram-negative bacterium that frequently leads to chronic infections highly resistant to antibiotic therapy in dogs. Also, it causes mild human brucellosis compared to other zoonotic ... -
Capsular-defective Porphyromonas gingivalis mutant strains induce less alveolar bone resorption than W50 wild-type strain due to a decreased Th1/Th17 immune response and less osteoclast activity
(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 ... -
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 ... -
Development of a self-report questionnaire designed for populationbased surveillance of gingivitis in adolescents: Assessment of content validity and reliability

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 Grampositive 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, 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 ... -

(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)Objective: In Aggregatibacter actinomycetemcomitans, different serotypes have been described based on lipopolysaccharide (LPS) antigenicity. When T lymphocytes were stimulated with these serotypes, different patterns of ... -
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 ...
