    • Activation of RANKL-induced osteoclasts and memory T lymphocytes by Porphyromonas gingivalis is serotype dependant 
      Vernal Astudillo, Rolando; Díaz Zúñiga, Jaime; Melgar Rodríguez, Samanta; Pujol, Myriam; Díaz Guerra, Eva; Silva, Augusto; Sanz, Mariano; García Sanz, José (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 ...
    • Differential expression of CC chemokines (CCLs) and receptors (CCRs) by human T lymphocytes in response to ...

      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 
      Díaz Zúñiga, Jaime; Melgar Rodríguez, Samanta; Monasterio, Gustavo; Pujol, Myriam; Rojas, Leticia; Alvarez, Carla; Carvajal, Paola; Vernal Astudillo, Rolando (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 ...
    • Expresión de las quimioquinas CCL19 y CCL21 y su asociación con la salud o enfermedad periodontal 
      Muñoz Bustamante, Marcela Victoria. (Universidad de Chile, 2014)
      Durante las periodontitis, la respuesta inmune del hospedero involucra la producción de citoquinas, metaloproteinasas de la matriz, quimioquinas y receptores de quimioquinas que determinan la constitución de un ambiente ...
    • Gingival crevicular fluid as biomarker’s source for Alzheimer’s disease 
      Sansores España, Luis; Morales Lara, Francisca; Arriola Pacheco, Fabio; Astorga, Jessica; Paula Lima, Andrea; Carrillo Ávila, Arelly; Melgar Rodríguez, Samanta; Martínez Aguilar, Víctor; Díaz Zúñiga, Jaime (Universidad Costa Rica, Facultad Odontología, 2022)
      Periodontitis is a low-grade inflammatory disease caused by a subgingival dysbiotic microbiota. Multiple studies have determined the higher prevalence of tooth loss and poor oral hygiene in patients with Alzheimer's disease ...
    • Identificación de linfocitos Th9 y Th22 en periodontitis 
      Saavedra Pérez de Arce, José Francisco (Universidad de Chile, 2014)
      Las periodontitis son un conjunto de enfermedades de naturaleza inflamatoria y etiología infecciosa. El biofilm subgingival, constituido principalmente por bacterias anaerobias Gram-negativas, es el factor etiológico ...
    • Immunostimulatory activity of low-molecular-weight hyaluronan on dendritic cells stimulated with Aggregatibacter ... 
      Monasterio, Gustavo; Guevara, José; Ibarra, Juan; Castillo, Francisca; Díaz Zúñiga, Jaime; Alvarez, Carla; Cafferata, Emilio; Vernal Astudillo, Rolando (Springer Verlag, 2018)
      Objectives Periodontitis is a chronic inflammatory disease characterized by tooth-supporting tissue destruction, which is elicited by the host’s immune response triggered against periodonto-pathogen bacteria. During ...
    • 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 ...
    • Periodontitis and alzheimer's disease 
      Sansores España, Daniel; Carrillo Ávila, Arelly; Melgar Rodríguez, Samanta Azucena; Díaz Zúñiga, Jaime; Martínez Aguilar, Víctor (Medicina Oral, España, 2021)
      Background: Alzheimer's disease (AD), the main cause of dementia in the adult population, is characterized by a progressive loss of cognitive function. It is considered that neuroinflammation plays a fundamental role in ...
    • Serotype a of Aggregatibacter actinomycetemcomitans down-regulates the increased serotype b-induced cytokine ... 
      Rojas, Leticia; Melgar Rodríguez, Samanta; Díaz Zúñiga, Jaime; Alvarez, Carla; Monasterio, Gustavo; Rojas, Carolina; Carvajal, Paola; Vernal Astudillo, Rolando (Elsevier Ltd, 2018)
      Objective: In Aggregatibacter actinomycetemcomitans, different serotypes have been described based on LPS antigenicity. Mixed infection with the different A. actinomycetemcomitans serotypes is frequent in periodontitis ...
    • Serotype-dependent response of human dendritic cells stimulated with Aggregatibacter actinomycetemcomitans 
      Díaz Zúñiga, Jaime; Yáñez Figueroa, Juan Pablo; Álvarez, Carla; Melgar Rodríguez, Samanta; Hernández Ríos, Emma; Sanz, Mariano; Vernal Astudillo, Rolando (2014)
      Aim: Different serotypes of Aggregatibacter actinomycetemcomitans have been described based on the lipopolysaccharide (LPS)-O-polysaccharide antigenicity. In turn, a distinct effect of A. actinomycetemcomitans serotypes ...
    • T-lymphocyte phenotype and function triggered by Aggregatibacter actinomycetemcomitans is serotype-dependent
